The Bonneville got harder and harder to start on the Elefant to the point where I barely made it home. I then set about finding the problem. Turns out fault number 1 was a duff battery as a result of a short in the charger socket close to it. So far so good. Having put that right I still had no starter motor so set off from the battery, through the solenoid, to the motor with the result I took the motor off, did a jump lead/bench test and hey presto non-moving-parts-type-smoke-machine. I was lucky, Triumphant had one for £150 instead of the £500 the thieving Hinckley bar stewards and Nippon Denso mates wanted. Got it fitted and was rather miffed to find it didn't work. Found another short via corroded wiring (*****y alarm ready garbage by the look of it) near the horn and now got the full 13.8 V at the starter, but still no joy. I always work on the theory that if there is stuff going in but nothing works it's because the things blocked up. Now the meter says the engine is a perfect earth and so's the starter motor case. My jump lead from the starter motor case to the battery negative that now makes the thing run ;D says it isn't.
So, the Bonneville will get a nice thick second engine earth direct to the starter motor.
Anyone else seen this before? I'm guessing there is some rotten salty **** somewhere that'll conduct mA but balks at A?
Thoughts are appreciated as I hate faults that are cured by luck rather than judgement?
Cheers

Blimey, no wonder my four Elefant XBR is falling to bits :o :o :o

Well I found the bit that'll do mA but not A. Now starting on the main earth alone. Still going to fit an auxilliary.
