No lights work AC or dc

CaptPeace · 11-16-2023, 07:39 AM

OK, so here is a fun one my interior lights do not work none of them. They do not work on battery power. They do not work on shore power. The fuses are fine. The breakers are on at the panel. Not sure what to do now I can’t figure it out. The water pump works the fans in the bathroom work on AC or DC it’s just all of the lighting is out. I am pulling my hair out and believe me that’s the last thing I can afford to be doing lol.

Can you tell us what the-- make, model, and year is for your unit?

It’s a 2017 crossroads sundowner super light 33BH

Maybe connect thru ground fault receptacle? Try to reset any/all of those and see if you get lights.

I had no power to receptacles and found one tripped.

All receptacles are working properly. All of the everything works except the whites.

The lights are 12v., so the breakers don't apply. Have you checked all of your fuses?

Did they work in the past? Is this a new to you camper? Have you checked any bulbs? Usually the lights are on more than 1 fuse.

Yes they worked in the past but last time I was there 1/2 of them were out and the rest were very dim. All fuses are good. My next step will be to take out the electrical panel and see if there are fuses on the inverter. BTW I have no fuses for the lights. Only fuses I have are for the slide outs and the awning. I’ll be back up there on Monday and check the inverter.

I have never heard of any RV that doesn't have fuses for 12V power. Check the auto resetting breaker close to you battery. That would be the first step. This controls all power coming in and going to battery. Make sure you have power on both sides of breaker. (small square box with studs. wires connected to both sides. These fail all the time. also check for wire corrosion on the wires. Are they loose? Loose wires can cause dim lights.
Dirty frame ground from battery is a common issue as well.
Look at what is missing. Like does the fridge power up on 12v/propane (that portion is 12v)

Also take a picture of your breaker/fuse panel with doors open. Post it here and we can help more.

Just double checking you say you have a inverter. That should not have anything to do with the lights as it takes 12 volt DC and makes 120 volt AC. Look and see if you have a Converter. It will be located in the bottom of the power center where the breakers are or you may have a deck mount. In the case of a deck mount there will be 1-2 40 amp fuses there that are battery polarity fuses. They will blow if the battery is connected backwards.
A picture of your power center would help.

It sounds like your fuse at the converter has failed. Like dagst said, it’s usually located very close to the breaker panel.
