Electrical Block Diagram?

It sounds a little like you lost the coach battery ground.
Items listed should be powered through the converter 12-volt DC distribution panel. Fuses are behind a metal plate next to the 120-volt circuit breakers held in place by thumb screw.
Under the hood is a relay for the battery disconnect. It is possible that it is not operating properly.
Many Fleetwood products pump is using ground for switching.

Love Harbor Freight! Thanks. I used a phone charger to make sure all the recepticles worked. I'll do that again to find which breakers control what.

Everything was fine when I made this post, but now I have problems.

I was testing gen with the AC running, turned off the AC, shut down the gen, switched back to 115 from the house. A little while later at the coach control panel everything read full bars: all wet tanks, batteries, LP Gas... the other day they were all working correctly: tanks empty, LP Gas at 3/4. I don't know if the gen testing caused an issue with the control panel.

Yesterday I was replacing the LP Gas alarm, a wire slipped, touched ground and must have popped a fuse. I started chasing those wires down hand-over-hand through the floor, across the under belly and towards the engine compartment where I lost them. Tomorrow I'll pull all the fuses I can get to in the cab and a few other inline fuses. Those fuses in the engine compartment are unaccessable. (Why did they put that fuse box right under the master cylinder?)

This morning I noticed the water pump running. I checked that all the switches were off, so I disconnected the pump.

Tomorrow will be a full day running down those problems.

Sometimes I am my own worst enemy.

Looks all nice and neat. Is there things not working or just curious?

These Plug-in tester work good for identifying 120-volt circuits. Plug into receptacle then switch off breakers until the one that supplies power turns it off.

Yes, that's what I thought too. I'm looking for every thing right now just to get familiar with all the systems.

I found the owner manuals online for the coach and chassis.

Took the fire extinguisher holder out yesterday and found the below. Like everything else so far, I guess I can do it the fun way and use my multimeter to trace them down.

The only(?) thing left to test is the water heater on propane and electric.

It's been slow going up till now, but just retired last Friday, so I have more time to play. I may apply as a Walmart greeter (or similar) just to keep busy. I'm tired of worrying about the City's network going down or getting hit with ransomeware. I'm getting out of the computer world. (WOW! this is the first time I actually said that, almost teared up)



Thanks.

For the 12V fuse panel and 120v breaker(s)?
If not labeled (assuming or you wouldn’t be asking), it’s a bit of a chore but pulling or turning off each fuse/breaker 1 at a time and seeing what doesn’t work is probably the most straightforward way of figuring it out.

Good luck on getting any help from a dealer!
What system are you looking for diagram on?

I am looking for the coach wiring. I called Fleetwood, they said to contact a dealer.

Thanks

Are you looking for diagram for the chassis or for the coach?
Fleetwood has many drawings on website. Need to input rig information.
Chilton's offers manuals for Ford full size vans and Class C MHs.
