As it seems you have a multimeter start with the headlamp connector and work your way back till you hit some voltage. e.g. headlamp > switch > ignition > fuse > battery.

You say lost power so did it have power before?

I'm not famliar with the GZ125 but some small bikes of that era use direct lighting which draws AC direct from the alternator when the engine is running (and only when the engine is running) to power the headlight.
