Not sure where on the NC coast you are, but Howard RV in Wilmington and Piner RV in Morehead City are both excellent at providing service.

Have you got power at the output side of the breakers?

When you say you do not have power to the coach you need to know a few things. Lights and control circuits are generally 12 VDC so no lights does not equal no power. 12 VDC is usually switched with a large relay to shut off the house for storage. Look for a rocker switch by the door. Check the house battery voltage and make sure the batteries are above 12 VDC. Follow the heavy cable to the large relay and make sure it is on and there is power at both big terminals. Once you have power on both sides of the relay come back if you still have issues there.

Outlets are probably daisy chained off a GFI that can be tripped. Probably in the bathroom. Microwave is generally on it's own circuit so lights on the panel there is a good indicator that the AC is getting through the power cord, transfer switch and breaker box. If you have an inverter that is also a possible problem but seldom feeds the microwave.

In short get the house batteries supplying 12 VDC and the microwave panel on then come back with how it works...

Do you have an inverter ?

If you do, the power sometimes goes to it, then out to the circuits.

They often have push button resetable circuit breakers on the inverter case.

Glad to have you here in the forum with us. You'll like it here.

I agree with Twinboat. Check the inverter.

Happy Trails!!!

Can we assume the trans switch you refer to is a transmission switch and not a power transfer switch? If it's a transfer switch (or ATS) it could be mis-wired.

Sounds like it could be the ATS (automatic transfer switch) as Ken mentioned. One way to tell is to turn on the breaker from the power post and listen for the "klunk" when the switch transfers. This after about a two minute delay.

If there is no sound, it is probable that the switch is bad or was not wired correctly.

As everyone else has said, check the 120V reading at the INPUT to the ATS, and then check the other end, which feeds into the coach. ALSO, note that the power into the coach probably has a switch panel in a cabinet somewhere. It will have main breakers that need to be switched on.

Good luck,
Tom
