battery discharging.
« on: March 26, 2015, 04:37:05 AM »
Have last year swapped out the engine in my 2011 G5 after a huge increase in vibration. Picked up a unit from a crashed 2011 military. Whilst driving it solo I had no real problem with battery discharge. Now that I have fitted an Inder sidecar and am running at generally lower engine speeds I find the battery discharges . I have swapped the alternator stator from the old engine to the replacement with a slight improvement. But checking output shows erratic charging over fast idle. I suspect it may be the voltage regulator (RR unit in Enfield speak) that is the actual problem. The unit shows a part number 140211 . Does anyone know if this the Enfield part number or just the manufactures? I have looked on line and only find units with very different part numbers listed for sale. Anyone any ideas. 
Now 2011 Royal Enfield G5 and just added 2014 Continental GT

Not sure ... I just replaced mine but I got it from a dealer .. He said they were used on a few bikes not just enfields

I run a 1984 GL1200 with a sidecar attached. This year of Goldwing are renown for poor/ low power alternators.
I found with the sidecar, just the extra lights (position light, rear light front and rear indicators and brake light) which are legal requirements in the UK, are enough to work the alternator to it's output limits.
As well as getting your charging system checked, it might be worth measuring your bikes electrical draw just to be certain, you can always fit an auxillary battery in the sidecar to help out the electrical system.
