I was having a hard starting issue where the starter didn’t want to turn over. I did some checking and cleaned everything up. The connections were very dirty and corroded. After cleaning the connections the starter works great.

I then wanted to verify the system is charging ok. With the Key off I have 13.2 volts at the battery. I started the battery and it jumped to over 100 volts. I thought maybe my volt meter was bad so I did some other checking and then rechecked and sure enough the voltage was very high. Turned it off and the voltage went back down to 13.2.

I did an ohms test from the F terminal on the generator to ground and it buzzed so there is connectivity there. I thought maybe there was a problem with either the voltage regulator, or maybe the wiring so I disconnected the F terminal from the voltage regulator and did the same test. Still buzzed, so I then disconnected the wire from the F terminal on the generator and did the same test. It buzzed again.

I wanted to confirm, there should not be continuity from the F terminal on the generator to ground. From what I understand that is how you test the charging system is to ground the F terminal, so it sounds like I may have an internal short in my starter generator? Just want some thoughts before I tore it all down when it may not be needed.

Any ideas are greatly appreciated.

Thanks
