Did you flip any disconnect switches?
Assuming your batteries were good beforehand, and no switches flipped, I’d guess you just have a bad connection. Re-clean and tighten all connections.

Yes, make sure the disconnect switches are ON.


After verifying that they are connected properly, check for 12+VDC between the two large-gauge wires going from the battery bank to the coach.


Then turn the "salesman switch" off and back on.

no 12 volt

I cleaned all of the connections and I have power threw the main house fuse. I do not have any power to the disconnect switch by the entry door. No power to any lights, hot water heater, and thermostat. Is there a breaker or a fuse anywhere


that I have missed?

Was it working before you cleaned everything?

My coach is a 2001. I don't know if yours is the same, but I'd guess it is close. I'm guessing you have not reconnected your cables correctly. In other similar cases, the positive cable between the two series wired banks of house batteries was left off (the cable labeled 24 in the battery compartment drawing below).

All 12v power in the coach comes from the batteries. The circuit for the 12v fuse panel feeds through the salesman switch, but other circuits (steps, refrigerator, seats) do NOT go through the salesman switch.

Here are a couple of illustrations that my help.

Did you bump your high amp breaker relay switch, or blow a high amp fuse in the battery bay?

I checked the high amp fuse and it is ok, I have 12 volts to my inverter/charger. I can not find a high voltage switch.

Andy, thank you. I do not have power to any 12 volt. No lights, seats, steps, awning, salesman switch, not even the generator will start. I will check the cables again.

Is there 12 v at the battery terminals? I trust you used distilled water for the batteries.

Good idea to label all cables/wires attached to your batteries. A few pics can also help.

I have 6 6volt batteries, wired so that I have 3 sets of 2 equaling 3 12 volt banks. Do you know where the two cables from the cutoff switch by the front door are connected to the batteries? Apparently there should be a relay somewhere that I cannot find.

Unless you accidentally shorted something while doing the cleaning it is almost certainly in the battery bay you were working in.

The wires to the door cut-off switch lead to a relay. The cut-off switch wires are usually small gauge.

The relay will have two heavy gauge wires to it as well as the smaller cut-off switch wires. One of the heavy gauge wires leads to the battery bank, possibly through a second heavy switch and then to the positive battery terminals.

The other heavy gauge relay wire goes to the house fuse panel. When not on shore power or generator, there will be 12 volts across the two heavy gauge relay wires. This indicates the cut-off relay is "off". Zero volts means the relay is "on".

If relay is "off", it can be jumped to get your 12 volt system working.
