I was going to go for a couple of days, but when I hooked up, the light on my controller would not light. Had trailer lights, but apparently no brakes. Tried a few things to troubleshoot, but no luck.
My battery is old and to be replaced. My controller had been bulletproof - tekonsha voyager.
What is the most likely cause? Anybody willing to make suggestion?
Thanks,

With no lights it's most likely either a bad ground or no power to the hot line. No power could be caused by a fuse or loose connection or by something in the controller itself.
Good luck / Skip

My controller lights all the time regardless of whether or not my trailer is plugged in. When you put your foot on the brake pedal, does the controller screen do anything? I've plugged in before and not had the controller recognize I was plugged in. I reseated the wires in the cord head and put some dielectric grease on both ends of the plug and things were talking to each other again. But if you have no lights at all to the controller, it is something else.

My Dad's 2003 Ram 2500 Cummins did the same thing.
He had his trailer brake controller plugged into the factory harness under the dash. He was passing through so we had to trouble shoot this at night about 10-2 am, while he had his fiver attached.
Ok, what was the problem.
Best we could tell the wire that sent brake power FROM the brake controller to the 7Pin connector was no longer carrying current.
All the fuses for the tow package were good. We could find no visible break in the factory harness.
We replaced the brake controller initially thinking his controller went out. Problem was diagnosed by me as the brake controller was sending no brake power to the 7 way RV plug (incorrect diagnosis) .
After replacing the brake controller (guess what kind of brake controller is available at 10 PM on sunday night? Yup. Hopkins time based junk from Walmart. But a time based brake controller is MUCH better than NO brakes, which is what my Daddy had)
We found that the problem did not change. There was still NO power to the brakes.
To resolve this quickly I took a heavy gauge wire and ran it from the back of the Brake controller (the correct wire that sends brake power to the trailer) through the firewall main harness grommet and I ran it directly to the appropriate blade on the 7 way controller.
Well, now my dad has trailer brakes.
IMHO, you may be experiencing the same thing.
Thanks! And sorry this is so long.
