Crappy coupler?

[Noco]

I've got a 1969 overlander, when I tow, a check trailer alert goes off in my truck, I'm pretty sure it's because the original coupler sucks. Should I buy a simple coupler replacement or replace the entire tongue to a different style coupler?

What kind of TV? I don't think your TV can diagnose a coupler. An ITBC, however can diagnose a bad electrical circuit in the trailer brake system.. That's all I can think that you are experiencing.

That is the electrical connection (connector) not the coupler giving that indication. Shoot some electrical connector cleaner or WD 40 in and on it. Try again.

I've got an 06 ford powerstroke. Ya my electrical cable is pulled out of the socket on the trailer end. I've got a replacement for it so I'm hoping that will solve the check trailer warning issue. But there is a lot of play in the coupler, I believe it's called a Melvin coupler??? I'd like to make sure it's good to go too. I've replaced all runing gear and just wanna make sure it's safe to tow

Probably a Marvel coupler, you can purchase a rebuild kit from Vintage Trailer Supply and other vendors.

If you do need a new coupler, remember that it has lasted 45 years to date. It is hard for me to call that a "crappy coupler". Everything wears out. I found cracks in the one on my '74 Argosy, and had it removed and a new one installed. It was a 2 hour job and total cost including the coupler was in the range of $225.

But, like the others mentioned, it sounds like you are getting an alert for your brakes, as no tow vehicle cannot check the coupler as far as I know.

A new coupler can be welded on your existing tongue, or you can rebuild some couplers. I'd replace one that's seen a lot of wear over almost half a century. I do however agree that it's probably your emergency brake cable that's sending the check trailer light.

It's been a great coupler, but after half a century, it's now crappy and requires fixing. Thanks for the help
