I have a 1978 Bolens G11XL. The engine is an 11 HP Briggs and the charging system isn't working. When I first started troubleshooting the circuit, I found that the diode was a pile of black powder. Assuming (Dumb, Dumb, Dumb) that this was the problem, I replaced the diode (and, yes, the diode is in the proper polarity. I checked it three times because I don't trust myself) The circuit still isn't working. I did some tracking with my multimeter and found that the stator is pretty much shorted to ground (ringing 2.2 ohms, but it's a Harbor Freight meter). I also found that I'm getting 12 volts checking from the stator side of the diode to the + side of the battery whether the engine is running or not. Shouldn't there be 12 volts to the - side of the battery when the engine is running? Instead I read 0 volts to there. In my mind, this all means that the stator is at ground potential or shorted to ground. IMO there should be more resistance than 2 ohms in the windings of the stator but I don't know what should be there, and in any case, I'm not generating any power. Am I right about any or all of this? Any suggestions?
