We lost power to our fridge, after checking the fridge out I realized we had lost the 12 volts for our levelers as well as some of the other dash devices. I can still start the MH, and both chassis and cabin batteries have a good charge. Checked all fuses that I could find in the electrical junction box, and the "salesman switch" by the door.

Finally traced the issue to one wire that leads from the RV junction box back to the generator battery positive. I removed this cable in the junction box, jumpered back to the battery, and everything works as far as i can tell. This is not a good permanent solution, any ideas what the issue could be? I checked the Gen breakers and they are not tripped either.

Thanks

"Finally traced the issue to one wire that leads from the RV junction box back to the generator battery positive. "

Is the junction box your Battery Control Center (BCC)? Is there a manufacturer and part number?

Sorry, by junction I meant the rats nest of wires they put under the driverside window on the Landau.

What wire was it?
And how did you check fuses; visually or meter?

On the diagram, it is the large lug on the upper left. The largest wire that goes down. It actually goes from there straight to the Generator 12v in.

Fuses I visually inspected while tracking the wire.

1. If that wire was the heavy red wire connected to solenoid (A) (bottom center of the drawing) that is the AUX battery disconnect. See if that solenoid actually connects voltage when the "salesmen switch is thrown>

The row of circuit breakers along the right side of the panel can be reset by the small button on the side of the breaker.

The levelers have their own breaker to the left of that battery disconnect.

This is a better layout of the main wiring for the Landau. It's actually for the 2001, but the basic diagram may be easier to understand than the ball of yarn from GeorgieBoy.

More info is available here in the 2001 Owners Manual. The wire colors are different. http://www.coachmenrv.com/OwnersManuals/14128237.pdf

Need to mention- the 2001 drawing states the fuse blocks are located under the dash on the passenger side. True for 2001 model but our 2000 fuses are in that rats nest panel below the drivers seat. Ignition fuses are in the freightliner boxes in the back of that same compartment. (your ignition circuits work)
It sounds like power is not getting from the aux battery and by connecting direct to the battery you have bypassed the disconnect switch or the main 175amp fuse.
If you also do not have 12 volt interior power, lights, roof vent, tv booster, and emergency start switch, etc --the problem may be the Aux Batt disconnect circuit. Switch or solenoid..

Good luck...

Thanks!
That drawing is much easier to understand. 12v interior lights are working. As well as steps. You are probably right I will go back and check these connections again with the meter. I have to find that 175 amp fuse and check it.

I have a different electrical problem.
My slides just stopped. Manual shows a reset button but I cannot find it anywhere.
My coach is 2000 Pace Arrow Vision 35 ft. Can someone help?

What are these three solenoids actually supposed to do? Should there be continuity across the terminals?

rockinh · 02-21-2015, 10:58 AM

Ok I get it two on the right are positive from aux and chass batteries. The one on the left is the power in from chass and out to my levelers, fridge, ect. That's where there is a blockage. Is it a bad solenoid?

Hooligan · 02-23-2015, 10:33 AM

As you can see my layout is different??? (may be the same before you moved the cables??) The bottom relay with the white label is the Aux battery disconnect.
The upper right solenoid is the Emergency start relay and connects the Coach and chassis batteries together.
The upper left solenoid connects the chassis power when the ignition is on.

The black strip on the far right is the circuit breakers. They have a small black pin on the side that is visible when they trip.

I suspect one of your solenoids is not working. You should be able to hear them activate.

Hope this helps..
