Battery Cables
I am in the process of wiring up my winch, and I was thinking of upgrading my cables from the alternator to battery battery to fuse panel. And the same for ground. Hoping newer cables with lower OMH couldn't hurt. I have already had to buy a new battery to starter cable be cause the terminal was sized on the old battery. Ideas?

Winch has negative lead and positive lead which should go to the battery itself. Those other components are not relevant.

I know that, but I am wondering that a thicker gauge going from alternator to fuse box then to battery and finally to starter will increase power. When I had to get a aftermarket positive cable when mine sized on my old battery, the cable from battery to fuse was more then half the size.

Recommended cable size is based on power utilized/produced, i.e., by your starter/alternator. So, unless their power requirements grew (which they didn't if all you installed was a new battery), no need to change the cables.

It's called the "big 3" upgrade. I did it to my jeep after having done it on my old F150 and I can't really say it did much. At idle i get about 14.7v. The alternator output is controlled by the computer.

Oh and I used 0/1 gauge wire that I got at the local car audio shop.

Make your own, or has some nice cables if you don't want to make them. Very heavy duty from them (2/0G mains and 4G alt and fuse panel!) They also have the military style battery clamps which I would never do without now. They made them cheaper than I could buy the materials and crimpers myself, fwiw...

Just ordered a new set of cables. Can not wait to get her running again!

Just went for it and got the one from It was a bit more then I wanted to spend but they look like they are heavy duty and will last and be more dependable.

Got my cables today! Only thing is it does not come with alternator to batt. The guy from Jeepers said it was due to the fact a fuse was built in. Is there any merit to that? I kinda want a heavier cable. Also any tips on how to get the negative cables grounds loose?

I will be doing the 'big 3 upgrade' soon as well. The 3 grounds are over 16 years old, there is some serious dry rot inside the wires and it sure couldn't hurt to change em. Take a look at the 2 cables coming off your negative battery terminal and follow them down to your engine block and firewall. Also follow the wire coming off your alternator to your battery.

You do routine maintenance on everything else in your vehicle why would you tolerate any other lower performing part that could leave you stranded when it does finally go? The difference in upgrading/refreshing these components would most easily be explained by comparing a set of quality high end jumper cables to a cheap set. One recharges much faster allows more energy to pass through with less interference and the other barely works but does get the job done. You could very well see an improvement in any/all of your accessories as well your on board computers/sensors.

The guy wants low ohm wires. nothing wrong with that.
Make double sure you clean your battery terminals with a terminal cleaner and spray your terminals with some pink/red terminal protector. Mine were seized / corroded together too. It took some work to get them apart.
do your big 3. trace the wires, use good wire. Solder the connections and use some coating to keep crud out and off of them. Take the better wires over the cheap ones.
It's YOUR Jeep! don't let anyone else try to convince you that your going overboard.
It's YOUR Jeep! ;)
Google the wiring diagrams for a winch if you need to, or if nobody will give you the help you need.
P.m. me if you need anything.

Did you mention the alt wires to James? I got the circuit breaker kit from him for $45 extra, I received 4g wires for the alt and fuse panel, a resetable circuit breaker, and the 2/0 for the main battery power and grounds. Wicked overkill imho... just the way I like it :)

If you're in to making your own battery cables, consider going to a welding shop and buying bulk wire. Usually all the big sizes are available from about #4 to 4/0 and it is very flexible. It is made of more individual strands, so it can handle more amperage with less loss. Most will even crimp on ends for you.

James should add the CB kit to his site, there is no info that says it's available if wanted, and the cable disc doesn't say anything about it not coming with it :( I apologize for not mentioning it before EnglishBulldog.

No big deal. I am just wondering if I could make it myself with some amp power cable I have laying around, or if it needs to be fused. I have stock alternator.

Take the old cables off and measure their resistance with an OHM-meter or digital multimeter ($9 from Harbor Freight, even less with a coupon).

Now measure the resistance of the new cables you just bought (make sure they are the EXACT same length as the old ones).

Are the numbers significantly different? I highly doubt it.
