Inverter does not work until ignition turned on

[ptylerp]

Looking for advice on where to start trouble-shooting this issue. We have a 2020 Challenger 37fh, Refrigerator does not get power unless ignition switch is on. This just started happening in the past few days. I am sure there is a breaker tripped somewhere that between coach batteries and the inverter and when the ignition switch is turned on a relay must pick up and power the inverter from the chassis batteries.

I'll find it but just thought someone on here could save me a little time and point me in the right direction to start.

Thanks for your assistance.

Check the power button on the inverter itself. Sounds like the inverter has been turned off.

When you say "ignition switch is on" is the switch just on? Or do you mean the engine is running?

Does the fridge work when connected to SP?

The inverter is connected directly to the house batteries through it's own circuit breaker or large fuse located near the house batteries. Have you put a voltmeter on your house batteries to measure voltage?

Now it works. Did nothing but this AM it works fine. Thanks for all the advice though.
