Xantrex 458 Inverter not turning on

Hello,

We have a 04 Fleetwood Discovery 39J and I can't get the inverter to turn on. I checked the breaker in main cabinet under bed and 2 on inverter itself and both seem to be fine. Batteries are all new and good, showing 12.5V on main display. Can someone please point me in a direction to continue troubleshooting.

Just had the same problem. Replaced a 5a fuse inside the xantrex. Remove unit, a few sheet metal screws and locat fuse on the vertical board.

I opened it up found the small glass fuse which checked out fine then you got me thinking so I traced out the wires and found an in-line 300A fuse coming from the batteries and that was bad. Thanks for the help!
