99% of the time when a fuse blows immediately, you can almost guarantee you have a wire grounding out on the chassis somewhere. Start looking for a frayed/cut/broken wire.Scottie J
Also check the relays. I had one of the wires of the indicator relay touching and rubbing against the box untill the insulation was exposed.
May also consider replacing the main fuse with the stock 20A.. Then the other two with a LOWER rated fuse, like a five or a ten for now. In hopes that lower rated fuse will pop before the main. If it does.... you likely just isolated the circuit where the short is.
Tonight I took the bike out for a 15 mile round trip in the freezing cold pouring rain (which I wasn't expecting but that's another story).Lights and engine ran normally. No electrical trouble* of the kind I was having. Assume I solved it?*I did have one issue: intermittently, pulling in the clutch is triggering the high beam and the high beam indicator. But I don't think that's related to my electrical problem. If it continues I have a couple of ideas: either the bar mitt is slightly deforming the angle of the clutch lever, or when I gently laid the bike down on its side unexpectedly last month (nothing interesting to tell, I got unbalanced while working) I bent something in the lever housing
