170VAC coming from my Onan generator

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 how?
Regulator?

Thanks

    Governor! Does the genset sound like it is running overly fast?
    If you can see and get to the throttle linkage see if it is moving.

    Does your genset seem like it is running at a higher rpm than normal? You can buy cheap HZ meter plug it into your 120 v socket and adjust the speed to read the correct HZ at the proper rpm.
