Interior light won't work

[j_walker]

I recently purchased a 2000 Jayco eagle pop up camper. When we got it home and plugged it into 120v outlet everything electrical works except the interior lights and the outside lights.

I took a multi meter and tested continuity. I get tone through the safety switch, through the fuse block, and into the socket itself. Also It didn't come with a battery so I'm only relying on 120v power. Help me!

Bulbs? My outside light needed a new bulb in order to work.

Since those lights run off 12v your converter may not be working when plugged in and without a battery makes it hard to test. Also most popup campers have a battery shutoff switch which turns off 12v power when the top is down, find the switch and test it.

I checked the filaments on the bulbs and they all seem to be intact. There are 4 bulbs total and nothing works. The safety switch I referred to is the one you had mentioned and I get continuity through the switch so I'd say that's good also.

So your converter is not supplying 12v power. Continuity is great, but not if you aren't supplying voltage. What is the voltage drop across any of those fixtures? If not 12v, your converter is not making 12VDC from the 120VAC

You need to check for power from your converter. There are also a couple fuses in there as well. One may be blown.

There may also be a switch on front of the converter for battery/converter.

Hey guys so I did a little digging into this. I have 120v coming into the converter box. Check voltage across the fuses themselves and I don't get anything. Also checked across the light sockets themselves and still no voltage obviously since there isn't anything coming from the fuse block. Guessing bad converter box?

Since it sounds like you have access to the converter, is there a manufacturer/model number listed (often on the back of the unit)? This should lead you to a manual with a quick internet search. That manual might give you troubleshooting instructions for your specific model.

Another test; can you attach a 12v battery even temporarily? If you have a 7-pin harness, your TV can also energise the 12v circuit. If you get lights or other 12v sources with your TT or battery attached, then it is most probably the converter.

Also, the converter may have 12V output terminals that attach to the fuse block. If there isn't 12v there, then the problem must lie with the converter. However, as Grumpy says, there may be a switch, fuse, or circuit breaker internal to the converter as well. Look for that (ideally in the manual if you can locate it).

Thanks a bunch guys for the input, I came to the conclusion that the converter was bad so I purchased a new one and waiting for it to arrive to install. Will keep you all posted with the outcome.

I am currently in the middle of wiring in the new converter but am confused where the wire labeled converter hot goes. Does it tie in with the AC in from shore power and go to the main circuit or somewhere else? The wiring diagram only show it going into open space. I'll try to attach a photo of the wiring diagram.
