Hi, I have been restoring the bike for about 6 months now and its nearly all together, i put the new battery in and tried the electrics... the good news is it has a good spark :spin2: the side light works on the second click of the key and the back light works!

But no headlight no ignition light no neutral light and the horn dosn't work.. :eusa_doh: ..I havn't tried to start the bike yet as i want to get the electrics right first.

I will try to put a photo on here soon. If anyone has any advice as to what the problem could be it would be greatly apreciated.

it doesnt have an ignition light Pete, you mean oil light (bulb check)

I had one of these bikes about 30 years ago and i thought i remembered a red ignition light, maybe i am getting it mixed up with another bike.

Thanks for your advice! Am i right in thinking the headlight only works when the engine is running?

Thanks again Pete.

Thanks again Pete.

The red light is the oil level alarm, but it's on constantly when in neutral...as a bulb check

The headlight only works with the engine running, but the pilot works from battery

Problem solved, i presumed i had made a big mistake when putting the wireing together but no, i should have checked the easy things first.

The oil light bulb was blown and the neutral switch isn't working, Thanks for your advice folks.
