The headlight on my new (to me) Yamaha doesn't work (side light is fine) .There is no power at the bulb connector and then I traced to wiring to the fuse box and there is no power there. I suspect it might be the relay at fault as I have power going in and as far as I can tell none coming out.
This is the (possible) culprit and Yamaha would like £83.42 for a new one .
So could I just use something like this ....................
