What would cause a "AC Back Feed " with Red Fault light on and Battery Charge light blinking on monitor?? Have one in my bus and have tried the soft and hard reset to no avail. Looks like time to pull her and send it in and see if they can repair that puppy. Shore power and Generator power both work just won't go though the Inverter to keep 110 volt stuff running inside without the AC side up. Good thing about it is it's under 3 years old if I get it in pronto they might fix it on there dime. It has worked flawlessly up till now..
First check your regular transfere switch to make sure it is working. Mine was not working and did that. Changed the switch and the fault stopped.

Thanks Dave will check that. I know it transfers between shore (pole) power and generator power. Was told all electricity goes though this Magnum and more than likely is inside case. Always something.
The transfer switch that selects between shore power and generator will be outside and before your inverter feed. The inverter also has a transfer switch in it, but it switches between the power coming into the inverter (whether it is shore or generator) and inverter produced power. Hope this makes sense.
Thanks Guys.. I feel like a mushroom on this stuff. The transfer switch (box) is right beside the inverter in the bay. In doing the hard reset noticed the relay that controls the shutters on cruise airs behind bumper work off the house batteries (2) 8D Lifelines). Figured these were controlled from bus batteries but i guess they were an add on from converter.
