Re: Generator polarity??

Thanks for the diagram! I also found that because of my new cooper plug wires, my digital meter goes crazy when its too close to them. I made up some extra long leads so the meter can be well away from the engine compartment and it gives far more accurate readings now.

Today I tested the gen to be sure its putting out voltage. With the wires to the regulator removed, I grounded the field terminal to the case, and tested for voltage at the arm terminal. This gen is capable of producing well over 20volts (my meter went blank in the 20v range). Is this normal for a 6 volt gen? I also observed the regulator with the cover off will running the engine (wires all hooked back up) and there is no movement at any engine speed. I think It's safe to say its the VR that is the culprit. Is there anything that can be done to repair them beyond polishing the contacts? I ask because my neighbor restores vintage RC boats and repairs the old servos and what not, but I don't want to bug him if its a lost cause.. I know that's a pretty far stretch, but you never now if you don't ask..

I also am pretty sure the whine from the gen. is just the bearings. It makes the same noise even when the wires are all disconnected. I'll see if a good squirt of oil I'm the service port helps with that.
