Well, I got a chance to throw a multimeter on it and while it's running the voltage just steadily drops so there isn't a charge getting back to the battery. I have tested the rectifier and it seems to be out although I'm not absolutely sure what the readings should be but there isn't a big difference when switching the leads around in the diode test mode on the multimeter.

Is there a way to test the stator to see if it is working as it should be?
