G9 electrics diagram

Post by Floydella »

Hi can anyone provide details of a wiring diagram for 59 G9, magneto ignition, alternator and single lighting switch. It has been converted to 12 volt electrics? Thanks in anticipation,

Are you a) rewiring it? or b) it's already rewired and you need to check or alter something?

Your battery may be knackered or very low. Check your battery with a multimeter. You should have about 12.7 volts or so with the engine stopped.
Cheers Dave.

Hi

Sounds like you have lost continuity from the battery to the light switch - is there an in line fuse that has blown?
