electrical problem. (pop pop stop)

The generator needs to be tested disconnected. It is an isolated thing - not grounded to the bike at all. You pick any 2 of the 3 wires and measure. Then on to the other 2 combinations of 2 of the 3 wires.

For your DC at the battery, it seems you're doing OK. Still a little low, but enough to charge the battery. Go with it for now as things seem to be working.

You might rethink your battery. 4ah is low. Spec is 11ah.

I was measuring connected. Will measure everything and clean contacts when time allows.
4ah will need to do for now.
Also, I have a 55/65 bulb up front, could that account for lower voltage? It is california model. Lights are always on. I know european models can have lights off.

Headlight should not be an issue. However when idling, due to less reserve capacity of a 4ah battery .vs. an 11ah one, it would tend to discharge a little. From my own work with measuring voltages, 2000rpm is about the cross over point from using electricity to recharging.

Re-check things when all contacts are cleaned then monitor it to be sure battery get recharged. I have an idiot LED battery status monitor on my bikes. Green=12.5v or more. Red=lower. Blinking red= below 11v. Orange=above 15.5v
