Trailer running lites not working

Recommended Posts

carguy79ta

Hi guys, my trailer running lites are not working. My truck is a 13 Ram CTD, the trailor is a 2017  Extreme trip axle. Dont normally tow at night, but did over the weekend and noticed it. Newish truck, new trailer, WTH. Talked to my buddy who said it might be a bad ground to one of the many running lites. Guess I will start there. He said one loose ground will shut them all off. I will first start by putting 12v to the running lite prong hole...hmm that sounded bad..then check every ground...any thoughts? I did check the condition of the connection and it looked fine. Shot it with WD40, but to no avail.🤔

It’s every single running light? Your brake lights and turn lights work though? Isn’t there a dedicated wire in the 7 pin plug for running lights?

@ahopkinsVTX. Actually, when the trailer is plugged in to the truck, the rear running lites on the truck dont work either. Had to drive with the flashers on. And yep the brakes and blinkers all work. I will look into it this weekend. Dont know anything about these 7pin connectors, ..but will learn.

Hmmm, sounds like it could be on the truck end then. You’re going to loose me there if that’s the case. Wiring on new trucks is insane. Would be pretty easy to track down if it’s a bad plug or ground on the trailer.

Sounds like one of your lights is shorting out and causing the truck to not work.

you can jumper 12 volts to pin 3 and ground to pin 1 on the trailer for tail lights. Same to pin 5 and pin 1 will give you left brake light if you need to make sure of your set up. 

 

Good luck

I believe Dodge has dedicated fuses for the trailers. Should be on the drivers side fender well next to the battery. I think my 08 did. And I know my 14 did. My 18 does, and my 13 that is a shop truck, with a Hemi does as well.

@carguy79ta I actually just went out and looked. Should be F28,F29,F30. I also noticed the RT Turn/Brake at F81. Last time I needed fuses I had to go on Amazon. It is a weird fuse that none of the O’Reillys or Autozone’s around here carried.  Here is a link for an assortment

Wow. Thanks guys! I will  check the fuses first, then order some if need be, then put 12v to the pins and go from there. Ahop, Sparky and Balley thanks!

@ahopkinsVTX, @Sparky450, @Ballay, Success!! It was a fuse. I did check the voltage at the truck and trailer plugs and confirmed the fuse, then pulled it out with needle nose pliers. I would have pulled the fuse first but was afraid I would break it, it seemed in there pretty good, however YouTube showed  a guy doing it with the pliers so I pulled it and they had them at Advance. I bought 2 extras and I marked the fuse box. The extras in the truck.  Under the best of conditions, it is hard for me to read the black/grey printing.Thanks!

Just be careful, fuses don't typically die on their own behalf. Something killt it.
