It's keeps faulting out ( little red button pops out shuts off) I jumped exhaust temp still faults it reads 64 hz on start would that cause it to fault & shut off ? If so can it be jumped or by passed ?Thoughts appreciated

The fire alarm system can also cause this fault. At yearly fire inspection, both my gens shut down via the pop button at activation of alarm system

I would love to have that service manual as well if you still have it handy.

64hx no load is a bit high which means it’s running a little faster than it should. Could there be an over speed protection that would shut it down?

Otherwise, temporarily try bypassing the oil pressure switch as well as the coolant temp sensor. Some Ohnos also have a raw water flow switch which could fail. I always have a full set of sensors on board.

Any idea where this can be found?
