Went down today to bring the MH up for a trip tomorrow. Batteries were a little weak and the temps were about 30degrees. I started the generator and the block heater and let it run about 2 hours. When I went back she fired right up. My windshield shades, step, wipers, and heater fan wont work. Everything else seems ok. I've pulled and looked at every fuse I can find. Under the dash, and back by the breaker box and all are ok. 2005 Bounder 34h diesel. thanks in advance.

Also no slide power.

Step and slide power will have an inline fuse rear the house battery. Your on you one on the rest. Battery disconnect on?

Check your battery connections. Could possibly be a disconnect solenoid .

There should be a " run " solenoid that controls power to the accesseries.

Listen for it to clunk on and off with turning the key on and off ( not to the start position ).

Once located, see if it has power on one side with key off and power on both sides with key on. If its not passing power thru, replace it with a same type.

I found a blown 3 amp fuse in the battery compartment for the AUX START. When I replaced it, what I assume is the disconnect solenoid started humming. I still have the same problem with the dead circuits. Replace the solenoid you think. thanks

The solenoid has trombetta 114-1211-010 on it. Would that b the accessory solenoid?

That is probably the boost and isolation/charging solenoid.

If it has large, battery size cables on both sides, it interconnects the house and chassis battery for charging or boosting a low battery. Not the run solenoid.

A run solenoid would be near the fuses for the things not working. Look up front where all of the stuff that doesn't run is. The ignition switch can't handle all of the things that run when the key is turned on. The run solenoid is in place to handle the load. When off it will have no voltage on one side.

Ok, thanks. Ill see if I can find it in the morning.

I just wanted to update you all who helped on what I found. The circuit breaker in the BCC was tripped, and the 3amp fuse for the aux start was blown. After I tripped the breaker and replaced the fuse it seemed everything worked except the aux start. I replaced the aux start charge solenoid and all seems to work ok. thanks
