Good evening all. As luck would have it, the wife and I are to leave in the morning for a trip to Gulf Shores, AL and then probably on over to the Destin, FL area. Upon opening the cabinet door that houses the monitor panel, switches for the slide-outs and the Magnum Inverter/Charger Management Control Center. The display on the Inverter panel is showing "BACK FEED FAULT" and the Red Fault Light is illuminated and the Charging light is flashing. I've checked everything I know to check and even did a reset on the inverter according to an RV dealer in the area. I'm at a loss. Any help on this problem is greatly appreciated. Thank you.
Also, I've lost 110 VAC to the outlets in the Kitchen slide-out as well as the GFI in the bathroom. Thanks again.

There are two resets. Soft reset is via the button on the inverter.
A hard reset is done by disconnecting all DC power from the inverter and is a more extensive reset.

Will I get the same result by completely disconnecting the house batteries? Or is that what you meant? Thanks!

I had to totally disconnect all 12 volts before mine reset.

I have had good luck calling Magnum's technical support when every other option has failed.

You might. However I would disconnect the house and chassis batteries to make sure there is no back feed from the chassis batteries. This is the case on my coach.

Also make sure you are disconnected from shore power

Thanks! Will let you know how it works out.

Thank you! I did the hard reset via cutting shore power, disconnecting the ground from the chassis batteries and the coach batteries. Waited about 2-3 minutes then re-attached the battery grounds then shore power last. Worked like a charm! All systems working as they should. Thanks again!
