Negative Battery Cable Advice

Ok gang, the jeep wouldn't start yesterday morning. I got it jump started and off I went to work. I went out at lunch and messed with the battery cables and noticed my negative cable was a tad bit loose. I wiggled it, and then put the keys in the ignition and it started right up!
When I got home, I tried to tighten the bolt, and ended up destroying the terminal. I now have a small set of vise grips clamping the terminal together! (redneck-ish, I know)
There are 2 separate cables on the negative side that split from the battery terminal. One goes to the firewall, and the other to the engine block. I assume I need to replace the whole thing? I don't think I can replace just the terminal at the end. There isn't enough extra cable, unless I remove the cable from that factory flex hose???
My question is, does anyone know how much a negative battery cable cost?

At some point during jeep ownership, you will BUST A NUT!!!

You can build it yourself by getting:
- decent wire (#2 AWG is great -- get a set of thick jumper cables and cut off the ends...cheaper this way)
- copper lugs
- terminal posts

Cut to length and go from there

One tip: To compress the lugs onto the wire you'll need either a vice or a big azz hammer to smash the end down. Might also suggest some heat shrink to cover the ends to dress it up a bit.

Here's a sample of my rig's connections to give an idea:

nice job rketr...

Also, if you cut back your cable to re-crimp an end on it, be sure and replace it if the copper is green under the insulation. Or, cut back far enough to eliminate the green and get a fresh clean connection.

Battery Cables

If you work near a welding shop you could use welding cable which makes great cables. If you have a winch you may consider using Military Spec battery terminal clamps, they are better suited for load carrying than the Marine terminals. I have had the stud loosen up after using my winch under high load situation using the Marine Terminals.

Good Luck
