Getting ready for trip. Neither the left or right directionals are working on my 2012 Cameo 5er. The lights work, but no stop lights or directionals. I checked the plug for the truck and I have voltage for the lights, but not for blinkers, directional or stop lights. All the same filament on the bulb. For what I can tell all other 12V systems are working. Any ideas? Is there a separate fuse box just for 12V? If not any ideas to get them working. It is not nice to drive without break or blinker lights.... We live in the RV full time and it has been sitting on our pad for about 2 years without moving. All worked last time we were out.

There are no fuses on the trailer for the brake lights, turn signals or taillights, these are all powered by the truck. Some trucks do have separate fuses for the trailer lights.
I would start checking at the 7-pin connecter and work back to the taillight bulb connections.

So you are saying the truck receptacle for 7-pin is not powering these lights?
Does the truck itself have operating brake/turn signals? If so, it would likely be a bad connection in the harness to the 7-pin connector.
If truck stop lights not working, most likely a fuse under hood or dash. Your owners manual should give the exact fuse location.

Check your truck fuse box(es) to see if separate fuses for taillights and stoplights.
You can check the trailer brake lights by using a jumper at your 7 pin connector.

Howdy!
Had the same problems once. Rats got in and ate into the wiring. Was a real mess finding the problem.

Trailer fuses in the truck. Check location in truck's owner's manual. Most are in the fuse block under the hood.

When I used a jumper on the trailer connector I got 12 V for the lit back lights, but none no voltage for either directional. I am going to check the truck today, in case there is a problem there. Took apart the RV connector and cleaned it. All seem good there. If it was a bad ground, I am thinking the rear tail lights would not work, so there has to be a common denominator somewhere for the direction filament.

I beg to differ. Our trailer and one other we had in the past, had fuses on the wiring for the lights. They were located in an area close to the pinbox where the harness came into the trailer. My truck also has the trailer wiring on a separate fused circuit.

Yes ,and both right ,and left signals have a fuse for the trailer . It seems odd both would be blown at the same time , but it's sure possible . I have had one or the other blown ,but never both at the same time .
To the OP get your manual out ,and see where those fuses are in your truck . both Ram ,and Ford have separate fuses for the trailer light directional signals etc .
