fosdyke Posted August 8, 2010 Share Posted August 8, 2010 my 1981 yb100 (1 owner from new) been standing has a slight electrical problemo, headlight doesnt light up and indicators dont flash, only light up help? advice? regards Dom Hi Dom The headlight will only work with the bike running as it is powered from the flywheel magneto. As to the indicators they are always a bit of a problem on this bike - my experience is that a) They run better with the engine on! You need to have a good (fully charged battery) c) As the electrical system works on an earth return system the 'ground' on the indicators needs to be good for them to work well. I have never been able to get mine to work terribly successfully just on the battery - joys of the 6v system that was never really designed to power indicators I suppose.....

dan28 Posted August 8, 2010 Share Posted August 8, 2010 if you fitted led indicators they require less power to work so in theory should work better Hi Dom The headlight will only work with the bike running as it is powered from the flywheel magneto.
