Default short battery cable

My positive battery cable is a little short. Just short enuf that it pulls the battery away from the back of the box and won't let it be anchored down. How can I lengthen the cable? Do I have to replace the whole thing for almost $100?

Can you turn the battery around? If not go to your local auto parts and buy a longer one....

You can go to a welding supply and get the proper size welding cable. This is very high quality cable, very flexible with a high quality rubber jacket. You can get a ten foot pc. of this stuff for around 30 bucks. I found some good fittings at a commercial wholesale battery place. They may even crimp them on for you. You can also solder them on if you have a torch.

We used them all the time when I was in the Air Force.

Would it reach if you added a battery disconnect?

dont hack it! just do it right and run a complete battery cable front to back. Not worth the hassles it will create.

You might have enough slack in the cable as it runs through the tunnel.
We where able to get several inchs gained on ours on the starter end. It is not that tough but does take patience, small hands, a couple sockets and wrench's but really do-able with everything up in the tunnel.

Good Luck wro87

I believe I've read that it's proper to put the battery diconnect on the NEG. battery terminal, not on the POS.. Honest that's what I've read!

The original battery cables are copper clad aluminum and simply suck.
You cannot solder them. They will eventually corrode at the terminals and cause start problems. A lot of times it is improperly diagnosed as a starter or solenoid problem. That is why aluminum cable was outlawed for residential and commercial buildings. Power companies are the only ones still allowed to use it.

You can turn the battery around. Both my vettes are that way.

Or you can get the good welding cable and crimp and solder new ends on. Both available at a welding supply. It is then easy to use a disconnect if desired. This is the cable and disconnects I used. It is advised to use them at the neg terminal, but either post will work.

True, but it's more a matter of disconnecting the neg cable first so if your wrench comes into contact with metal it wont spark. But with the disconnect theres really no danger of that, especially since there's no metal in the vicinity of the battery in a Vette.

In another post I suggested turning the battery around and just about lost my head! Purists!

Guys,
I thought I would put my .02 in here on the disconnect. I am now currently redoing my cables because I used the negative for the disconnect. The problem with using the – side of he battery is if you need to run a small wire for the radio or clock, you must run a small ground wire from your battery. Ok that doesn’t sound too bad until you do, then find that the case of the radio or clock grounds the rest of the car. This renders your disconnect useless and could cause a fire if you “TRY” to start the car without reconnecting the disconnect. If you do forget and try to start the car, all of the current from the starter will try to pull it’s ground from the small wire you ran for your clock/radio. Ask me how I know this!!!!! For this reason alone the disconnect should be ran on the positive side.

You can use a jumper with a fuse holder in it and insert a 2 amp or even smaller fuse to run the clock, etc. Then when you try to start the car with the disconnect open you only blow the fuse.

That is a pic of the original labeled cable. The one below it in the porevious post with the copper ends is the one I made from welding cable.



You can see the copper coating on the aluminum strands.




This is the welding cable. Many more strands.





You can buy the disconnects pictured above with a small fused accessory wire for keeping memory etc.

Yes this is an alternative, but how do you get around the problem of the case grounding the rest of the car? The fuse would solve the problem of burning the car to the ground, but I use my cutoff to make sure my battery doesn’t run down during shows. I will open my doors at shows and that makes the interior lights come on. To me the simple solution was to run the cutoff through the positive. All of this is JMO, I just wish someone would have mentioned this problem when I was researching where to put the battery cutoff.
