So, I just noticed no AC power when plugged in this morning. We have a 2019 E450 2350. All breakers confirmed on. I have tried the following troubleshooting so far and decided to share on the forum before I start taking the bed apart to get to the connections.
1. Unplug external AC power. Turn on Generator. Confirmed the transfer switch worked and the generator provided power to all equipment. Confirmed cabin batteries charged some during the generator use. Turn off generator.
2. Start vehicle, review cabin battery status and no power from vehicle running
3. Reviewed cable connection at battery compartment and all looks tight; but per 1 and 2 that is not where the problem would be.
What am I missing, is there another breaker somewhere that may be tripped preventing AC Power?
