Generator is producing power but not to the lugs.

Hello everyone. I have an MEP 803a Fermont that will make power. I can even adjust the power with the volts knob, however the contactor is not closing and the A/C circuit interruptor light stays on. Even if the unit is not running and the switch is the prime run position, the light will stay on. I installed an aftermarket voltage regulator from Mr. Klopp but nothing changed. Everything on the front panel works as it should, and the unit cranks just find. But the (k1) contactor won’t close and the volts, and hertz meter won’t work.

Sounds like your K1 relay is not working right. That light can only come on when the K1 is energized, OR, the contacts are stuck. Take a rubber mallet and TAP, not beat it like Man Mountain Dean, tap it a few times. If that wont help, you need to remove the K1 and open it up. Clean it and or unstick it.

I will give that a try. Right now the contactor is in the open position I’m curious which wire closes K1. Maybe it’s not getting the proper voltage?
