I am having some problems with the lights on my recently acquired XT350.All the electrics(indicators,brake light etc) work apart from the headlight and rear light.These work if you run power directly to them,so it's not the bulbs.The earths are O.K.The battery is fully charged.There is only one fuse on the bike ,that is O.K.I have started to work my way around the wiring loom,the power seems to disappear somewhere between the ignion switch and the light switch,but I have not found where yet.Can anyone offer any suggestions or even tell me that the lights only work with the engine running before I go any further,
