1995 Ultrasport, MH 3470 electrical

Where to begin.

Major stuff. The dual 30 amp fuses and solenoids under the hood are both blown. The leveling ramps are underpowered, the drivers power window suddenly stopped working, and the engine battery boost does not engage with the house batteries to help start the engine.

What are they for, where do they come from , where do they go, how can I get replacement parts when Damon does not carry any information on this year?

When did you get this coach?
Did these things suddenly appear or did they happen over time?

Hello Vintage,

Thank you for replying to the post.

I bought the coach with one solenoid bad, the other was mounted up with everything by a "RV mechanic" and blew a year later.

Have you replaced them both to see what happens?
I presume that by solenoids you mean the things that look like starter relays. They are readily available at PepBoys Etc.


The leveling ramps are underpowered,

Try cleaning all the electrical connections to the power unit.

the drivers power window suddenly stopped working,

Could be fuse or water getting into the door and causing a short.

and the engine battery boost does not engage with the house batteries to help start the engine.

That is probably one of your solenoids that is bad.

Sam, How well versed are you with electrical things? You might have to take things apart and see where they go one circuit at a time.

Go to Home Depot etc. and get some wire markers. They are small numbers and or letters for you to stick on the wires and their associated posts before you take them off. They take clear closeup pictures you can look at later. Assume nothing. PO's have their own system of jimmying wires and you don't know what that system is. I have removed and replaced several circuits in my coach that were from the PO.

1/2 inch masking tape and a permanent marker is what I used under the shade tree for years. The advantage is you could be more detailed in how you identify each wire.

Sam,

Do you mean the leveling rams? Or what most of us call the levelers? Have you tried to level with the engine running? I know that mine says to set the parking brake and run the engine, the current draw is too much for battery operation alone.
