Truck Bed AC Adapter

[Scott64pw]

I've got a 2021 Powerwagon that has an AC inverter with a port in the bed. I'm having trouble getting power to the plug in the bed. There is a button to the left of the steering wheel to activate that port. When I press it, it blinks and then turns off. No power is making it to the port. Any ideas?

Maybe check the fuse for that port...

I did check Fuse #4 that is for the AC inverter. Is there another fuse that might protect that particular adapter?

Do you have power to the cab outlets?

yes, those are active and providing power.

I’d trace the wires and if you don’t find anything you may have to take it to the dealer.

OK, so I looked under the bed and found a dangling harness..... So it looked like it was just disconnected.

I found another empty connection within range of the harness, so I guessed it goes in there . To me it seems the harness will plug in backwards. The first two pictures (pic1 and pic2) are how i was able to get it to go in, but the last one (pic3) seems like it would be the right way. When connecting it up like the first two pictures, the AC plug works.

I checked the AC plug with a tester and it’s showing an open ground. I started thinking that maybe this is normal for an automobile inverter. Does anyone know what theirs looks like?

My cabin plugs do the same thing.
