Sounds like the loom has had it or at least the section around the headstock, get the outer tape off and have a proper look at the wiring. The target is maybe a trapped or worn wire(s). You are going to need patience and a wiring diagram for this, good luck.

hi &

you have either a broken black or yellow wire/Yellow & black wire ... cut back the loom casing around the headstock & you should find the wire. But you may also find that there is a loose connection behind the h/l cowl.
