Tracking down brake failure

Two months ago, a trip to Colorado and the brakes were fine. This weekend, ready to sell the Overlander, the buyers TV couldn't activate the brakes and no road side turn or brake light. Curb side was OK. Buyer says his unit was working, but I need to check. I sold my TV, so no 7pin to connect to. Any suggestions beyond checking continuity? Are there any fuses in-line anywhere I need to look for? Any other suggestions on tracking, tracing and checking? I'd like to save that 125.00/hour service charge.

it might be a case of old wiring pattern vs. new wiring pattern on the umbilical cord. this should help:

If you have power back to the drums that's good, the only other electrical parts are the brake magnets themselves it is possible but unlikely they are both bad. However they can be damaged by pulling the brake away pin and letting voltage run through them for a period of time.
It would be good if you could find someone with a TV and hook up to it to test. That's simple and fast. I'm thinking perhaps the buyer might have a problem he doesn't know about. Could be as simple as bent pins on his 7 way or yours. If not you may have to replace the magnets. Hopefully it will be the easier of the two.

You really need to try another TV. It took me quite a while to wire the cable from my TV to the TT. I had to use the wiring diagram from my TT manual and the wiring Diagram from the TV manual. They have made changes in the wiring from 1971 TT and 2006 TV wiring so I could not go just by the TT manual. Blew a few fuses along the way. Works great now. When I picked up the trailer I could only get the Turn/Brake lights to work. The PO had wired up a 4way flat to the trailer (wrong I might add). I did the rest at home with no one looking over my shoulder going "Oh, so that's how you do it and Oh, so that's where that goes". This is on a trailer that "Everything works great". Good luck

You have 3 distinct electrical problems. That indicates the problem is in the connection of the TV and trailer.

Remove the plug on your trailer cord and rearrange the wires to meet the current configuration. This will give you the correct arrangement.

All valid suggestions, and I thank you all. Plug is fine. It worked two months ago on my TV. Silly me, sold the TV. Buyer had the problem and backed out of the purchase. Turns out, Camping World and 65.00 later, the guys tv must have had the problem because they confirm all systems operational. It's all good. New buyer tonight and he gets a confirmation receipt from CW saying its all working. A pretty good guarantee for a 42 year old unit. AND, we got full price - no discount for questions in the back of your mind.
