Thanks All, for your thoughts and suggestions. I really don't mind testing, checking and double checking everything, cuz I want to be darn sure before spending significant time and money replacing the stator. I have a HD service manual for my specific bike and year. The charging system schematic shows the regulator's +12 output wire connected to the AUX post of the 30 Amp Main Circuit Breaker. The other side of the circuit breaker's BATT post connects to the starter and from the starter to the battery. This Main Circuit Breaker and the wiring have to be good and functioning properly, or the bike wouldn't start and continue to run until the battery discharges.
I have double checked the ground wire from the regulator. It is cleanly bolted to the frame. I've used an ohmmeter to measure countinuity from here to another part of the chassis. I've also measured +12V from battery POS directly to this regulator ground wire where it's bolted.
I work with and understand electronics, which is why I'm still puzzled that if the stator is putting out AC, and the regulator is new, and all the wiring seems to be good, why don't I get 14V across the battery, even if the stator isn't putting out adequate current? The only explanation I can come up with is that the stator appears to measure good when it's unloaded, but under load (connected to the regulator) it must not be good?
