Probably your battery was dead. You charged it when you drove. Is the battery old? If my battery dies I hook it up to my truck and use the truck for power.

nkdf:

Everyone so far as said battery.. a quick way to test is to plug in your 7way connector to the truck after it dies and see if it runs again.. if it does – it’s the battery. Otherwise it might be a thermal cutoff, could be due to hardening grease or your wiring / connection is failing. It cools off after a while and resets itself.

want-to-say-this:

Battery was dead. Or it’s dying and you got a few more uses.

TundraYetti11:

Maybe a dead battery….?

BackgroundGrade:

As others have said, sounds like battery.

When I use mine, I disconnect the battery on my trailer and keep the trailer plugged in to my tow vehicle with the engine running to avoid draining the trailer battery.

excessive-smoker:

When you’re connected to the truck the connector not only connects lights but there is 12v line that probably charged you back up

Kostelnik:

Doesn’t look like it was suggested yet, so try this: new battery for the trailer.

Source: My hitch died on me! This morning while hitching it was sounding slow. I was able to back my truck into place right before it completely died and I had to finish attaching it manually. I’ve gotten to my new campground and the hitch works again. Can anybody tell me what’s wrong with it?
