TT all light work except running lights

[User177-4]

My first post :-) so I hope I have made it to the right place.

I have a 2018 Bullet Colt 171RKCT.
All of my lights work (brake, turn signals, etc) except the running lights. I am at a loss because I am not electrically inclined and don't know where to start. All advice is greatly appreciated.

Have tried to get wiring diagram from Keystone without success.

Thank you....

Welcome to the forum

As long as you have a good battery installed, Start at the trailer cord you plug into the truck. Hold it so that the openings are facing you and the locking tab is UP. Now take a jumper wire and connect the top two “blades” one on each side of the tab. If you have running lights then the issue is in your tow vehicle, possibly a blown fuse.

If you still have no lights then post back for further instructions.

My 2017 Chevy Silverado had an under dash fuse just for those running lights.

Thanks for the info. It turned out to be a fuse on my Gladiator.
