Yamaha GT80 Wiring

[Milan]

have a GT80.
Headlight & Tailight not working.

Maybe engine is supposed to be running for them to work?
Started Engine, still no luck.

I have attached the wiring diagram.

I suppose there is a " Run " signal from the engine, that then passes back up to the ignition switch, and then transfers to the Blue wires for this operation.

Anyone know what color wire that would be, so i can check?
Green / Red?

Otherwise I am just going to wire the ignition ON brown wire.
So the lights come on with the key

looks like the orange and red wire is the charge/lighting coil wire. i would guess that yes, it has to be running for the headlight to work, common on smaller bike sof the era, especially 6v ones. I have no direct experience with these models in particular though.
