Voltage drop is going to be the big issue. Which means that your winch may not run as effeciently, but like I said, if you run the winch off the rear bumper that could solve that issue. The other is voltage drop between your alternator and your batteries. I'm not exactly sure how big of cable you should use. Somewhere in the internet, I've seen a chart that shows how big the cable should be verses how many feet.....Ramdough said:I was thinking that the cable lengths would be around 10-15 ft. I plan on running a rope through my truck so I can buy exactly the right length (plus a foot or two). That cable gets expensive and I don't want to waste any.
Normal winch electrical cables are 2 AWG. THey are short, and used intermittently.
I think that a 1/0 cable would take alot of amps before it heated up enoug to matter. Even for a long and hard pull, the duration is not all that extreme. Plus there would be alot of coper to absorb the heat.
Just some thoughts.
