3 to 2 wire trailer light converter?

I recently set my wife's car (2017 Jeep Cherokee) up for TOAD duty, afterward hooked it up to the coach to test out everything and it all worked. We were going to take it on a short trip last weekend, got it hooked up and found the TOAD had no brake lights. After a bit of digging I found the problem was the 3 wire to 2 wire converter mounted under the back bumper of the motorhome (it fails to output the stop signal, red wire stop signal input and ground are both good). This is at least the 3rd 3 wire to 2 wire converter which has been installed on the motorhome. When rewiring things a couple of years ago I discovered a disconnected 3 wire to 2 wire converter, plus the connected one was dead, I replaced it with the same model unpowered converter, and now a couple of years later after just a single test hookup, though probably 15,000 miles of on the road it too has died.


So I am getting ready to replace this one with a Curt brand powered converter, but not their top of the line model, model 56146, but before I do I wanted to ask if I am making a mistake, should I invest in a better converter unit, is there such a thing? etc.

Ya know,
I've dealt with both the 3-2 converter and the 2-3 converter, both Curt and, I think in all my goofing around with them on various toads, I may have had ONE go bad. If it did, that was looooooong ago. Normally, they're pretty dependable but, I've read on here that there's been one or two that have gave up the ghost.

If you're having repeated failures of them, you're either REALLY unlucky in purchasing bad parts or, I guess it's possible that something in your system is causing the failure of them. I by far, am no electrical wizard in the 12VDC world, not by any stretch so, I'm not sure which way to point you to here.

12V is 12V, period. I can't think of any reason that your coach might be feeding those 3-2 converters TOO MUCH VOLTAGE in order for them to burn out or fail. Now, if your toad is potentially causing the problem, other than sending some 12V signals to each of your toads tail light filaments to see if they all work without issue, I don't know what else to advise on here. Good luck.
Scott
