Pulser Coil
« on: January 17, 2014, 08:35:32 PM »
  I was diddling around inside the left side case of my '08 Classic today mounting a small spare fuse holder & wishing there was a way to do away with ALL the wires & black boxes & connectors. It would be So neat.

   Anyway - what does the small black epoxied-shut box called a Pulser Coil do?  It's about 1"x1"x1/2".

I'm guessing it is the turn signal flasher.

           Nope. The flasher's under the seat. This little box is called a Pulser Coil on the schematic. It's a separate component from the Ignition Coil.

A pulse coil triggers the ignition to fire. An exciter coil provides voltage in an AC system. Battery supplies voltage in a DC system.

           It's not a Hall Effect trigger.  It's not on a rotating part of the engine; how could it trigger the spark? It's in the left side case (as I already said) & it's completely epoxied solid. I'll go take pictures.  Be back in a while.

            The component is right in the center above the brake light switch.
         

             Seems to me I remember doing something with the wires to this thing back in 2010 when I switched the TCI Unit to the green one. That must have been when I plugged the green connector into the white one. Also two wires have been cut.

             Tomorrow I'm going to track where that one sleeve of wires goes. This thing may be serving no purpose at all.

You could always unplug it and toss it in the trash.

Then, when something on your motorcycle doesn't work you can say, "So!  THAT'S what that thing did!  Now, where I toss it?"

          That's what I'm gonna do in the Spring when the bike's running again.
           
          I'm gonna trace where the one sleeve of wires goes that must have a connector on the end. Then with the bike running, I'll disconnect it.

          What's really surprising is no one can tell me what it is. Yet. It's just a stock electrical component on an '08 AVL.

Dear Tooseevee,

it look very familiar however its fitted on my car  :o!! I maybe total off topic and wrong however,  ???...

I don't have that part on my bike ( maybe it came on the export models) , however, I have Vauxhall Victor ( aka Contessa Classic as it was called in India) and the fuel injection system uses a 'Multilink' box exactly like in the pic. The car 's parts manual refers to it as the 'Iginition Amplifier'. It is connected between the CPS and the Distributor. few years back it went bad and the car would miss, had poor starting or would fire on 2 cylinders. I replaced it and it started working fine. I understood that EFI system used low voltage signal for the Crank sensor and sends it to this amplifier which then sends a high voltage current to the distributor coil.

ok, I have confused myself now !

That looks something like a slightly bigger version of the regulator on my late '70's Honda CB500T, which has just two terminals on it, so could it be one of those?
 That said, as it is called a 'pulser coil', it may more likely be an external part of the ignition trigger system and in either case, it is very much needed on your machine.

Many modern ignition systems have a condenser (not like those on a points set up) to provide seamless voltage flow and spike protection, possible?

I'm pretty sure that the Pulser Coil is hooked up directly to the Flux Capacitor and helps converts the fuel into the required 1.21 Gigawatts.  Without it, you won't be able to break the time/space continuum when you hit 88mph.  Be careful not to ground yourself out on it, 1.21 gigawatts will send you to the skies!   ;D

I believe the pulser coil is in with the generator. It's the green and white wires coming out of the motor. Could that box be the starter auto cutoff?

Well here's  a good explanation but why it's  in the sidebox..Maybe the wires go to a pickup point and they figure to put the actual coil in a protected area...I don't have one as mine (06) is the older points/condenser..The article goes into good detail re. when they started to use this technique to generate 12 v...If it's providing voltage to ECU, I wouldn't remove it while its running...GM...

             My bike ('08 AVL Classic as stated before) doesn't have a generator. It has a three-wire alternator, electronic ignition, carburetor, 5-speed, kick & electric start.  I don't know what you're thinking of, but that ain't it. This component is in the left side case, NOT in the engine or in the primary case. It has eight (8) wires coming out of it.

             No, I understand what a pulser coil is as described in your linked article. That's a "trigger" triggered by a magnet attached to the flywheel of whatever & it "tells" the coil when to fire the plug each time the magnet goes by.

              That can't be what this little black box is. It's mounted in the left side case & has 8 wires going to it &/or coming out of it (whatever) & it is sealed shut with epoxy. It's not an add-on either. It's a factory part of the bike. It has its own bracket inside the side case.

          I was incorrect in my first post. It Can't be the Pulser Coil I see labelled on my schematic. THAT labelled coil is the one that's mounted on whatever rotating part of the engine it's mounted on. My schematic shows that the pulser coil is a two-wire component (which it would be). The little black box in the side case I'm trying to ID has 8 wires.

ISTRC when the problem of backfiring & resultant sprag clutch damage reared its ugly head another solution was tried before the green TCI box appeared as a replacement for the original black one, a little box intended to delay the ignition from firing for a couple of revolutions to allow the e-start to get the engine up to cranking speed first. Could be one of those?  :-\

The Pulser Coil, (often called Pickup Coil, Timing Coil or Crankshaft Position Indicater ) is responsible for providing the timing signal to the ignition control box on modern motorcycles with solid-state ignition system. The Pulser Coil, as a unit, is not usually serviceable. It is a sealed component, and should be replaced if determined to be a problem. Pulser Coil problems sometimes manifest themselves in hot running situations, but usually failures result in no spark at all. When the pulser coil fails it will usually produce no output pulse, or a very weak one.
I've had several go bad in Triumphs. They quit working when they get overheated at continuous high speeds on a hot day. After the bike quits, which will definitely be at some spot where you didn't need that, like an HOV lane during rush hour, after it cools down a few minutes it will work again until it gets hot again. Slowing down helps it last a bit longer.

            You haven't been reading my posts, Bare. This is NOT the pickup trigger coil. It's in the left side case where the starter relay is. As I said before; I know what a pickup coil is. This is not the pickup coil.

             I'm thinking now that Adrian below is correct. It just might be the spark delay sprag saver that was on the bikes with the black TCI Units.

             I can't remember the details (it was 4 years ago), but I installed the green TCI 4 years ago. This would explain why the two connectors that previously went to the TCI are now plugged into each other. The connections to the TCI are not needed now because the delay is internal to the green TCI unit. I got instructions with the green TCI that must have told me to do this, but, as I say, I don't remember the details. I was doing a lot to the bike at that time.

            I believe you're absolutely right (see my post to barenekkid) & thanks for jogging my memory back 4 years.

             I remember all this vaguely now from when I replaced the black TCI Unit with the updated green one 4 years ago.

             Only two small green wires out of the 8 in this little black box are being used now & I can't trace where they go yet. They go out of the side case into a two-wire plug connector under the seat & then into the main harness (still green) & forward. When I trace where they go I'll let ya'all know.

    As I said before two green wires come out of the mystery black box then to a two-wire connector & then into the main harness & forward.

     I've spent an hour down there trying to find two green wires coming out of the harness at the headlight end of the bike. Pulled the headlight & can't find anything in there either ("Abandon hope all ye who enter there"). I hope I didn't loosen any of the hundred little black ground connectors that are in there. I can't check until the bat tree goes back in.

        The green wires do not go to the coil; those are a red/white & a brown. The two green wires are the only two out of the 8 that appear hooked to something. They do not go to the TCI Unit.

         I am just curious enough now to dewrap the whole harness to see where those two (@#%$*&) green wires go; maybe they change colors inside the harness although I don't see any lumps that might be connectors. I'll order a roll of '50s style harness wrap in the meantime.

          I neatened up my rear directional light wires also while I was down there. I had left them a mess since the new tail light & relocating the directionals.

         More later.

So is there a problem or are you just trying to figure out what the box does?  I know you don't want to believe it but I too think it has something to do with your ignition.  It sounds like the only way you're going to find out is by opening up the wire harness.  I have a feeling once you do you're going to find 2 wires running to some sort of a trigger somewhere.  JMHO

            No problem. I've just got my curiosity back up & now I can't let it go.

             I've just come up from an hour & 15 minutes of harness unwrapping. This is an '08 & I hope the new ones are better. My hands hurt so bad I had to quit. Whoever wrapped these wires should be fired or get some kind of award; Super Tape Wrapper Boy of the Month.

              It's three layers of the toughest, stickiest most stubborn &*@#*& tape I've ever come across. I got about 16" & had to quit.

               All I know so far is that the two greens that come out of the side case are spliced into a few more greens of the same gauge & go somewhere (I don't know where yet. I DO know that two of them branch off & go back inSIDE the left side case where the ends just plug together with a RE type factory bullet plug.

                Maybe? it's meant to disable this whole "green wire" circuit by unplugging this one plug which is totally accessible in the side box? Not buried in the rat's nest under the seat (which I aim to fix).

                 Only ONE green wire goes forward inside the harness where everything exits out of the harness just aft of the nacelle. It does not go into the primary. Next time I go down I'll verify the colors coming out of the primary cover; I believe they're three yellows & they go to the regulator. The wires in this harness go nowhere near the engine or the starter. They go to the nacelle with two branching off to the coil.

                  I don't mind rewrapping this harness (I've done whole cars). At least I'll know what's in there, get rid of this tape nightmare & the next owner won't have to deal with it. I would NEVER wrap this much immoveable stickytape around wires; it must have taken 2 hours & it's a nightmare to get off.

   After another afternoon of (1) finishing unwrapping the harness, (2) sorting out the rat's nest of small wires under the seat & (3) pulling all the green wires out of the side case & laying it all out where it can be looked at I've solved the little black box mystery.

   First of all only ONE green wire goes forward in the harness & that wire is separate & has nothing to do with all these other green wires. I could not see this until everything was laid out where it could be seen. That green wire goes to the front brake light switch (if I had straightened out the rat's nest under the seat FIRST I would have known this).

           Secondly none of the other green wires that go in & out of the side case & wander around under the seat do ANYthing. They don't go anywhere any more & I remember vaguely now what happened. I created the confusion when I installed the new green TCI Unit 4 years ago. I didn't finish the job then; I only cut the wires I was sure of then. I should have gotten rid of them all.

      I didn't know as much about the bike 4 years ago as I do now. I was still a little scared of it.

So, the little black box was a part of the old RE "Black box" system?   The newer "Green box" doesn't use it.

  Final chapter.

          Attached are two pictures of just part of the tape nightmare,
the old black TCI Unit & some of the "green wire to nowhere".

          The first TCI had two connectors (the green ones). The next one (in the picture) had the added white connector. This is what the connector from the black box plugged into. The black box was the spark delay added to save the sprag.

          The new green TCI Unit has the delay incorporated into the
TCI itself so the third connector is not used at all & the little black box is not plugged into anything & is redundant. I cleaned up some of the wires & left the box in the side case & forgot about it 4 years ago. If I had finished then, I would not be doing this now. Luckily I found the old TCI & connectors in my box &  of "stuff" & it helped to jog my memory.

          I hooked the battery up, checked all the lights, verified that the green wire goes to the front brake light switch, turned the engine over with the starter & feel confident now that I can rewrap all these wires before the engine is running again.

            Right.

            Another funny thing is that the November 2004 AVL Parts Book I have does NOT have the little black 8-wire box, but it DOES have the three connector TCI Unit. I don't know if it was black or green in the 2004 Parts Book.

            My March 2008 Classic had the black TCI. I got the green one free from CMW early in 2011 (I bought the bike brand new in December 2010) & installed it then. Makes me wonder what were the first bikes with the green TCI installed on the line & NO little black box. Or maybe ALL the AVLs got the black TCI Unit except the Electra.

          I need help ;)   ;) Why do I think about shit like this??

            I'm going to go rest now  ;D & try to put the whole thing out of my mind & just concentrate on how deep I want to get into my head.  And maybe piston. I'll be much better tomorrow & Wednesday morning they say I get to blow more snow.

So even tho the black box was inop, we were technically right about it's purpose.  ;)   Glad you got it figured out.  Did you eliminate the extra wires?

           Yes, you were right. I believe, with you, that it was a spark delay device they plugged into the black TCI Unit as a fix. Then the delay capability was included internally in the new green TCI Unit.

            Yes, I got rid of all the unused green wires & I've laid out all the wires in the area under the seat cleanly where I can look at them. Next (when the vintage style '50s harness tape gets here) is to locate them well & wrap them all cleanly & continue on up that great lump of wires that goes forward under the tank & into the nacelle.

             I think I'll count those wires that go forward. There's a huge shitload of them (my shovel runs on about 7 wires).

              The temp dropped like mad overnight. Snow tonight & into tomorrow. Very cold in garage - didn't stay long enough to run the heater. Put the battery back in the warmroom.

               There are 30 wires that go forward from under the seat. Two branch off & go to the coil; 28! go into the nacelle & handlebar switches.

Hey Tooseevee, i am glad you figured out the much ado about nothing problem  ;D ;D ;D. And no more whining about your poor sore fingers. Here in Michigan we call this time of year "rotted splice season". I have spent all week tracing and repairing salt water soaked wiring. It would boggle your mind how one tiny nick in the insulation of a CAN wire can stop an $100,000 SUV dead in it's tracks.
ROVERman, get it!

           It wouldn't boggle my mind at all. I understand perfectly. I've done stuff like that & worse, in the cold, my whole life since I grew up in Wyoming & then spent since 1959 mostly on the East Coast freezing some more. I, like you, just kept on keepin 'on no matter what & most of my joint problems are from a genetic problem I can do nothing to stop; the cold just makes it worse from the summer which is only horrendous  :).

         Just the 10 years I spent in the CG as an Engineman & ET maintaining everything on lifeboat stations (and going out in unbelievable weather, year 'round to rescue IDIOTS), a 125' cutter & a couple of lighthouses was torture most every day, but that & all the other horrendous jobs I've had just made me tougher & stubborner & meaner so that now at close to 76 I'm still doing it.

           I understand exactly what you're going through. Just don't ever minimize what others go through

           Color me not as mean as I sound.

            Lifelong chronic pain rots your brain after a while & can make you touchy if you're not constantly on your guard against that. It comes to dominate your life which is why I can't seem to avoid mentioning my hands sometimes. And I wish it was ONLY my hands; it's every single joint, tendon, ligament & fiber now. Things I used to be able to do for hours are now limited to minutes & is why I'm so detail oriented. And stubborn.

          The way my mind is made I HAD to figure out the TCI & the black box & the wiring problem even though there was no problem. I HAVE to know what's going on. Can't help it. Does that make sense?

          And I still love Jack Black, too  ;)

I believe the pulser coil is in with the generator. It's the green and white wires coming out of the motor. Could that box be the starter auto cutoff?

       You were the first to get it correct.

        The final question that's been bugging me got answered just a few minutes ago when I went down & unwrapped the wires coming out of the primary. (I should have done this before tonight).

        I remember three large yellows coming out. I found that there are also two very small gauge wires coming out that were wrapped along with the three large yellows. They were wrapped together all the way up to the connectors.

        These two come from the Pulser Coil attached near the rotating part of the alternator.

         MY confusion started because on my schematic the Pulser Coil is just sitting out there on the drawing with nothing around it. Just a square with two wires. They should have drawn it in a simple pictorial alternator & I would have known right away what it was.

          Instead I started thinking that the little box in the left case was the Pulser Coil when (I know now) it was the Spark Delay (which originally plugged into the 3rd connector on the black TCI Unit).

          The little Spark Delay box is NOT on the schematic.

          It's all clear to me now, including the evolution of all the TCI Units & I hope the rest of you guys are totally confused :)   ;)

           Let's consider this thread closed unless someone has a question  ;)

           Cheyenne my first 18 years. Small farm/ranch 'til 12 then small rural house with my single mother nurse mom. Had a travelin' mom, too, so we were all over the place while I was growing up (my dad was killed in a car wreck near Ottumwa Iowa in 1940 when I was two). I'd been to all the States by 18.

            CG after high school (graduated in '56). 10 years. Cal for two years (125' Cutter Ewing in Alameda)  after boot camp in Cape May NJ. Two CG schools, Engineman & ET, then lifeboat stations & a couple lighthouses, lots of small boats. Wife threatened to divorce me if I went to Vietnam in '67 so I got out. The rest is long story like everybody else my age.

I was in Casper from '49-'63 when I joined the Navy, I guess I took your place, I went to Nam in '68. While there we went to Japan for a little R&R and went down to the Yamaha factory in Hamamatsu and saw them loading the trucks with brand new DT-1s. I wanted to buy one there, but I got lucky as the Navy wouldn't let us bring back bikes. I spent my money on a Canon Pellix and a bunch of lenses, By lucky means I never bought a Jap dirt bike until many years after that, the European stuff was far better handling in those days! I did ride some of them and mostly they scared the hell outta me!

Wow, 2cv, I'm glad that you figured out that rats nest, or part of it.  I have been looking longingly at unwrapping that huge mess and rerouting or eliminating some of it. I had wondered if some of the loom had left over components like the timing tower up the right side of the engine.  I installed the larger tri-bar light last weekend and thought, I have got to get these wires fixed.  I started mapping it out last summer, but got interrupted by a bad illness.  I am making plans to move and so buttoned up my 2008 even though the sprag is still a mess.  So when my shop is resituated, first the sprag, and then the rats nest.  When I replace the old TCI with the new green one, I get to remove the "pulser" in the left case.  I'm wanting to relocate all my fuses and components to one of the right or left cases and get them out from under the seat.  Thanks for figuring it out.
This bike was stored for 3.5 years.  It had fallen on its side for awhile. I claimed it about a year and a half ago. Thus the low miles and inexperienced owner.

             You can't do anything about the 30 wires that run forward wrapped in three layers of sticky tape; they all Go Somewhere & Do Something. You can wrap them better, but that's about it.

             BUT you can do a lot with the mess under the seat & in the left side case. I feel a lot better now that I know where every wire goes & what it does. The only thing in my left side case now is the starter relay & under the seat is no longer a rat's nest.

              If I live long enough I want to clean up what I can inside the headlight nacelle, but right now I have enough irons in the fire & don't want to add any more. With the head work finished & a new carb to rejet & sort out, I just want a running bike again.

               Oh, yeah. The Pulser you mention (in the left side case) is actually a spark delay component that the factory added to the T.C.I circuit to try to prevent electric start kickbacks. It's not on ANY schematic. You'll see how my schematic confused me at first if you read this thread thru from the beginning again.
