Hi Jerry. I read the manual and now what you are saying is beginning to make sense. Sorry. I am not an electrician.
I had the generator and battery checked by professional shops. They are both fine.
I think I have an extra regulator so I can take it apart and see if I can understand the rest of what you are saying before tearing into the one on the truck. I think my wiring is fine. It appears to match up with the schematic.
Thank you for your help and patience.
