Hello all, have trouble with my generac generator, 0046661, sn 3968855, v 125/240, amp 125/62.5, 15kw NG. I am looking for a field boost uplift kit for this unit not sure if kit #0H07850SRV will work for this unit. Changed brushes and cleaned slip rings I think this is the last thing I can try, when I find out why I have no output power when running.

If you momentarily jump 12V to the 4 wire when it first starts, does the unit continue to produce normal voltage on its own? DO NOT leave 12V connected to the 4 wire for more than a second or two.

Did try that and had no voltage output, I have changed the brushes and cleaned the slip rings twice, I had two spare sets, still no output.

What is your rotor resistance at the voltage regulator (between 0 and 4 wires) with them removed from the AVR?

A field boost kit isn't going to help if you can't make power with a jumper wire.
