Winch wiring, splicing high amp wires?

I got my 8k winch and i'm going to wire it up, the only problem is the cables arn't long enough. Is there a correct way to splice the wires? I was thinking waterproof terminals if i can find some big enough. Any other ideas?

Get some welding cable and replace the ones that are too short with the length that you'll need.

You may want to take the opportunity and connect the positive via a continuous duty solenoid. Then you can have a kill switch to shut down all power to the winch. As for the negative side, several guys here have run some pretty sweet ground bus bars. This can eliminate other issues at the same time. [img]images/icons/smile.gif[/img]

Re: Winch wiring, splicing high amp wires?

Consider that over 10ft, 2-gauge wire looses 2 volts at 400 amps -- that includes length of both positive and ground together. Think about that before you splice a bunch of it together. That will make the winch go from pulling 400A to 470A -- which makes for an overheated winch and more voltage drop..... you get the picture.

If you really need to, you can get more of that 2-gauge stuff at most autoparts stores for about $1.00/foot. Just buy enough of it to go wherever you need it.

That 2/0 welding cable costs about $2.00/foot, and works much better, but is real heavy -- like 1#/foot. It only looses like .2V at 10ft for the same 400A. That makes your winch and battery much happier.

For covering connections, you can buy heat-shrink tubing at most electrical supply houses. They will sell most any size you want. It costs about $3.00/foot or so for the stuff that works with 2/0 welding cable. That liquid electrical tape stuff or plasti-dip should do the trick too.

Best regards

Hey fellow michigan jeeper! Go to the welding supply and get some 2/0 and then you can get some ends at your local parts supply. You will be very happy later ken
