I bought a 2,000# superwinch for my ATV.
The one on it from a previous owner seemed weak.
I mounted a new marine battery on the front rack and used this style of quick connect to connect the winch to the battery or, the battery to the ATV.
Sorry I should have cropped the picture.
Once I got the new winch and started to install it, I realized that the spec's were misleading. It came with a circuit breaker. I don't recall the exact value of the breaker but it was 50 amps lower than the current the winch had to draw to pull 2,000# on the first wrap of the cable on the drum.
I had intended to use the winch to pull heavy items in awkward places but actually it is so useless, it acts like a storage drum for the cable and I pull with the ATV rather than the winch.
The lesson I learned is not to trust the advertised spec's. Further a real PTO driven winch like large tow trucks and military trucks use is a far superior product than the electric ones.
Regarding the use of Dynema lines instead of cable, I emailed Superwinch and asked if I could replace the cable with the synthetic line. Their answer was NO with the only comment that the drum would damage the synthetic.
