Electric failure

#1 PostAuthor: tim.25 » Wed Sep 06, 2023 5:07 pm

So took the a4 up to Boxhill on Sunday about 40 miles from me, no problems.
Very near home on the way back indicators not working, dodgy aftermarket relay I thought.
Got home, stopped bike, went to put in garage and no start! Just Oil, Neutral lights and horn, nothing else, no lights etc.
Any ideas anyone before I strip it apart.
Thanks

Kill switch / starter button switch gear earth, or the wiring to battery.

Check the connectors under the tank near the headstock had something similar and one of these was slightly loose ( multi connectors)

Rather weirdly, I wired an earth from starter solenoid directly to the battery and everything was fine again.
Only thing now is I have a very slight flicker on the lights when I put indicators on, sure that's a dodgy earth somewhere.
Bought a PMC solenoid from ZPOWER so maybe that will help.
Will only use it a couple more times this year but I do have something to play with in the winter now.
