I have a winch I can buy for $200 that is almost brand new. It is a 12v.
Vortec 9500 # winch. I can use it for some skidding I need to do onto my
trailer, but then, would hang it on an I beam dolly for hoisting. Since it
is 12v. what would I use as a power supply that would give me the same as
an automotive setup?
