Can someone please tell me if an "oil temp sensor" is the same thing as a "low oil sensor" in an Onan gas generator? I have been doing a lot of reading and have noticed that most of the problems with surging and shutting down of generators seem to be heat related, and may possibly involve that sensor. My generator, a 4000 watt KW, recently began having the same issues, which could also be caused by a bad fuel pump or fuel filter, but which I have yet to rule out. The dilemma I have is that my generator runs for some twenty minutes (in So. Ca. heat exceeding well over 100 degrees, in the shade, parked), before shutting down, which in my mind, would rule out those two as the culprits, otherwise, I believe the generator would not run at all, I think. The problem is that I don't know if my particular generator even has one of the sensors I mentioned. Can someone please help me? Thx.
