No power in sleeper

If you've made sure that your device is working, then like most electrical problems, we start where there's no power and trace it back with a continuity light. Everything electrical is fused somewhere, you just need to find it. If you have a wiring schematic it will show you how the wire is routed, but most fuse panels are labeled now accordingly. If you've located the fuse that powers the sleeper and you have juice on both sides of it, then the problem lies between it and the sleeper somewhere, likely a bad wire connection near the sleeper power-point.

 

Never had a 389 so I don't know if it has more than one fuse panel. A little confused because you say there is a fuse box in the sleeper that's not getting power.

Attaching a Pete fuse panel diagram from online. Left hand side, 3rd from bottom, 20 amp labeled sleeper. Hope that helps.

 

Hope you were able to find the electro issue so you could plug in your peace-maker / clam-hammer.

We all need a little relief now and again.

 

Mine were corroded when I bought the truck. Had the dealer to change them. They had to order them. When the mechanic changed them, he forgot to put the fuse in. The entire sleeper was dead.
I know what you mean by sleeper panel. It's the panel under the bed in the right jockey box.
That's where even my satellite gets it's power.

 

I just had this problem with my prostar so they may differ. Mine was a 100amp fusable link on the driver side firewall.

 

There's a 4"x4"distribution box that power your fuse boxes. It's located on the firewall on drivers side under hood, check these terminals for power and/or look for corrosion.
