Drivers side 12 v lights will not light. How do I find the problem? Where do I start aside from bulbs?

Hi, if you have no idea how to use a voltmeter and you have this many electrical problems I strongly recommend that you take your rig to a qualified RV repair shop. I have spent a lot of time working on both 12v and 120v as wel as other low voltage systems. This is not the best time to start experimenting now.

Thank you, yes I have a volt meter, I also have no idea how to use it.

LOL

You need to find your converter which is usually in the bedroom and it has next to it a fuse panel with the little Spade fuses in it. The power from the battery goes through these fuses before the switches and the lights. If you do not find any blown fuses then I would pop the switch out and jumper across the contacts with a screwdriver and see if the lights will work.
A dead battery is hard to jump using the boost switch as you may have to hold it down for five minutes or more to get enough charge. Do you have a voltmeter?

2000 Pace Arrow Vision, gas V 10. The lights have individual switches.

My 12 v power comes from two coach batteries those are new and charged. Possibly this may influence your assistance? The Aux Battery start will not jump my engine battery. I tried when we went to pick up the bus after winter storage had to get a jump from service truck.

Welcome to the class a section instead of around the campfire. It would help if we could find what class A you have. I'll guess it's a gas class A. Are the lights that do not work on their own switch or are they on a switch that operates both sides of the ceiling lights. If on their own switch you need to find that noisy thing that makes 12 V power and next to it is a fuse panel with the little plug-in Spade fuses. One of those imay be blown . If the light share a common switch then you have a loose wire hopefully at the switch.
My two word answer is: Good luck.

Have you checked your fuse panel? The ones for the interior 12-volt devices?

[Gjac]

Do you have 12v at the socket?

But I do have 12v problems with towed. The brake buddy 12v oulet has stopped working I must now us cig lighter outlet.

[bigred1cav]

Inside, sorry for lack of information. Ceiling 12v lights also do not work on drivers side.

Where would I look for ground or where would I ground 12v to ground all 12v?

[Grandpere]

could be a bulb, but i bet it is a loose or bad ground wire.

[donn0128]

Insid or outside? Likey a bad ground.

I'm going to make an assumption that you're talking about the clearance/running lights on a towable rig.

First, check all bulbs in the circuit that is not operating. Not knowing your model, the bulbs could be wired in series and if one goes out on that circuit, they all go out.

If all the bulbs are good, you might have a loose connection. pull each light fixture out and see if you have voltage coming into it and going out of it. T If not track back towards the tow vehicle and determine where the open circuit is.
