I believe it was the snap connector (it was semi-loose) and/or the small gauge wire. It could have been another internal connector problem, but not likely since that was the second new one. No time or desire to perform more detailed testing. Other than the winch itself, that was the only key changes. I had one warm day to work on it, before the bitter cold comes again tonight no time to waste. Dropping from 50 degreesF down to 3F. Not fun working in unheated garage!

What are you going to do with the old winch might I ask, try to return it ?

I'm going to try to return it. If they won't take it or only give me a portion back then I may keep it and mount to the deck or tree and use for dragging a sled of firewood to the house, or other projects. They can be quite handy. I don't think I would bother trying to hook it back up to another vehicle after that experience.

I had a 17 foot long Walnut tree truck that a guy use one of these winches he bought at Tracker Supply to pull up on his flat bed trailer. Worked great with no damage to my grass.

Good to hear!

Next project for next winter heated garage maybe ..🤣

Lol, that would be nice! I'm thinking I may put a small wood burning stove for the external garage. I probably wouldn't use it much, but sure nice to have when needed!

My neighbored has that in his external garage. He has one of those metal quonset types. Gets toasty warm .
