12V accessories do not work......

[02rockwood]

I am trying to figure out what is wrong. I have a 2002 Rockwood 1610. When I am hooked up to shore power the 12v accessories (interior lights and furnace) do not work. If the battery is charged, the lights will work (haven't tried the furnance this way), however the battery doesn't stay charged very long.

I have located the kill switch and it all appears to be in tact.

The fan isn't running on the converter in either situation. We have taken a multimeter and tested the fuse area and there is current to that.

We have tried to look at the wires and there is nothing obviously wrong with them (disconnected or anything).

Converter is Centurion 3000 CS 1200.

Not sure if the kill switch needs to be replaced, or the converter, or if there may be something else that needs to be looked at.

Others will chine in as well, but sounds like your converter is fried. Make sure the breaker for it isn't tripped.

I have flipped the breaker off and on again to check but it didn't make a difference.

I only see the two breakers on the front of the converter and 4 fuses.........not sure if there is anything elsewhere

As you have a multimeter, check the voltage across the battery when the camper is plugged into shorepower. That'll measure the output of the converter and it should be at least 13.5 V.

One item you left out, do you have 120VAC inside the coach? If you do you need to confirm the ac is hot to the converter inlet. If so the converter may have an issue internally.

Yes we do have 120 when hooked up to shore power. I am not sure what you mean by "confirm the ac is hot to the converter inlet".

Check power 120 vac is up to the conv, not just at circuit brk.

a typical reason for 12v not working, when the 120v does, is that the owner reversed the battery wires, setting off a resettable inline circuit breaker.
they are usually located along the trailer's tongue, between the battery and the front of the trailer. there's usually a little black button to reset with.

otherwise, there's usually a plunger switch that the sink top pushes down onto, when it's flipped up, during setup.
if the plunger switch is malfunctioning, the 12v stuff doesn't work.
