I've tried to test the three yellow wires but no ohms, no volts, no ah, nothing...dead
The rectifier is new: I got the one VRRPM3H of oregonmotorcyclespart that is an improvement over the earlier separate voltage regulator and rectifier. The connector is ok, no molten wires
The engine runs regularly: it seems ok but the battery is not being charged
I don't know what else I can test before pull the engine. The stator is not testable, isn't true?
