Positive Battery Cable Replacement Alternatives?

[tarix]

79 911 SC has been sitting off and on for a couple of years now and the abuse has taken its toll on the battery terminals.

The negative is salvagable, but also easily replaced. The positive one is apparently a bear to replace.

Because of a PO's car alarm I'm going to lose 2-3 inches of the positive cable in order to put a new connector on. There's no slack in the cable and thus it will no longer reach the battery post.

What exactly are my options? I've thought about rewiring it a bit and using a power distribution block as a bit of a patch. (That would also solve my amplifier woes when I get to the audio portion of my 911 experiment.)

Any suggestions? (Also, anyone know the gauge of the big and small power leads that come off the battery?)

Home store elec depts have a neat solid set screw style splice. I used one when I reconfigured the cables to fit the battery in the smugglers box. @ layers of large shrink wrap makes it look pro.

4/0 welding cable is the best.

I recommend that you install a battery cut off switch. It solves your problem and (of course) makes it very easy to disconnect the battery.
Connect the old positive wire (now too short) to one post on the switch and get a new cable from the other connection on the switch to the battery +.


I think you can get both the switch and a bracket to hold it from TRE http://www.tremotorsports.com/Home.htm

Excellent answer.
