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.....

if you fitted led indicators they require less power to work so in theory should work better
