It's a 1995 4000 BGE. I posted earlier but wanted to focus in on this problem. I tested the lead coming into the breaker switch and it was a consistent 170 VAC. What should I check next and h...

This "M" spec Emerald runs at 1800 rpm and has an electronic voltage regulator. assuming governor speed is somewhat close to correct, then the high ac voltage is almost always caused by faulty voltage regulator. the field circuits are "stuck" in full field mode.
Flight Systems part number for the VR is model 305. Have installed dozens of these, with excellent results. better price and warranty than Onan part.
They are a great company.
The genset circuit breaker trips off. That was the original issue.
Do you think that the 170 VAC feed to the Automatic Transfer Switch damaged the ATS?
It's looking like that's the issue considering when I unhooked the ATS the breaker didn't trip.
I wanted to solve the high voltage issue first obviously before replacing the ATS if that's the issue.
Shore power works fine as does 12 VDC.
It is looking like a new regulator and new ATS might be what I need.
