you should have 4 circuit breakers on that bike. Main, lights, accessory and ignition. They are near the battery but the seat or battery may have to come off to access them. The main breaker should be down from the positive battery terminal. If all power is off then the main is the one to check. If that is okay you may be losing power somewhere else like the ignition switch power to the other circuit breakers. You will need a multimeter to check for battery voltage on the breakers and switch.
The breakers should switch back on unless they are faulty or you have a persistent short in the wires.
Your circuit breakers should get power from the ignition switch.
I would check for power to the key switch and through the key switch to the circuit breakers. If the positive side of the circuits seems
good then check the grounds on the battery and frame.
Regulator could be disconnected while testing for power
in case of problems there. the stator should not interfere with the main power circuits.
