I'm not so concerned with how its wired, but rather preventing a live heavy gauge wire from starting a fire when the winch isn't in use. Some examples:
- Poorly routed cable suffers rubbing against a sharp metal when the frame/body twists going up an obstacle (I know this is user error, so I'm going to not do this).
- Front end collision that pinches/punctures the shielding around the wire causing an arc/fire.
More along the lines of asking blaine since he has seen many recoveries in JV(More than I ever will), if there is a preferred setup over the tradition 10ft(or so) positive/negative cable joining both posts of the battery to both posts of the winch.
Also I did not know you had a dual battery setup
. I gotta talk to you about that over a PM sometime.
