The run the generator until it shuts down and see if the switch tripped. You can do the same for coolant temperature, etc. I would put a heavy load on the unit and see if that accelerates the shutdown sequence. The higher the load the higher the exhaust gas temperature. High egt can come from a restriction in the shower head, (diverting the spray away from the sensor), restriction in heat exchanger or oil cooler, etc. It's also not unusual for exhaust temp sensors to go bad.thanks again, we checked all the sensors and all seem to be in good order. We checked the temperatures everywhere we could, and read normal. after an 1 1/2 hr we shut it down and went home, we did have a load on it.
now someone is telling me that Kohler is no longer really trying to help people with 7.3e and basically they too have thrown their hands up on this.
Thoughts on the 7.3e? on what to try next?? TIA
