99 Windsor 120 Volt Problem

[traveler999]

My coach has been in storage for awhile and I noticed I didn't have any power to the Microwave. In checking I have power on both legs to the main power panel that has all of the heavy loads, but I have no power to an auxiliary panel for the outlets, microwave, etc. I can't see where the power for this panel comes from. Does anybody have any drawings or ideas?

Check the breakers on the inverter.

Dennis is correct and you should check the breakers on the inverter. Also make sure the inverter is actually turned on. If you have a remote control panel for the inverter then you can turn it on and off from the panel. If all else fails then you need to unplug from shorepower and with the generator off then disconnect the main negative cable from your house batteries for a ten count then hook it back up. This should reset the inverter.

There is only one breaker on the inverter and it looks okay

turns It looks like I have a toasted Inveter/Convertor. When I close the breakers to the inverter the breakers at the house that are supplying power to the coach trip. I turned the switch on the inverter that I believe turns the convertor off, and it still pops the breakers at the house

If you are on a 20 amp shore power the inverter/charger and other loads may be tripping the breaker trying to charge a partially discharged house battery bank depending what your settings are. Try with generator if you are on a lower amp shore circuit, you might get lucky.

Thanks, but I disconnected the batteries and had the same problem.

Sorry for taking so long to close this out, but here is what I found

I did isolate the problem to the (Trace 2012) Inverter/Converter. I found a drop in replacement at VISONE and everything is working fine.
When I got the old unit on the bench I rigged it up with a single phase 115V on both of the inputs and every thing was fine, but when I used 220 where the phases were opposite polarity, it popped the circuit breaker. There is a relay inside the inverter that switches from shore power to inverter power that could be stuck. The outputs are normally115/220 volts because the are tied to the inputs which are 115/220volts out of phase, when the inverter is supplying the outputs the relay should open and then tie the inverter single phase output to both of the outputs. This is the only place that I can see where a short likethis could happen.

When I get ambitious I will try and tear the old unit apart.
