Hey guys. The battery connector terminals on my truck are corroded. As a result, I can't get the bolts to turn to tighten them onto the battery. I cleaned them with battery cleaner and then tried using liquid wrench to turn them but the nuts still won't budge. As a result, the terminals just rest on the battery and every once in a while will bounce off completely leaving me without power. So, whats the best solution here? Thanks alot.

 

Well if the connectors cannot be tightened onto the terminals, I'd expect that you'd want to look at replacing the connectors. Go to your local auto-parts store, buy some new connectors and put them on.

If you want to make it really pretty, you might want to look at shrink wrap and all that jazz. Otherwise just chop off the existing connectors, strip the wire back and clamp them into the new connectors.

 

Do not drive the truck that way, you will cause power surges that will kill your ECU, BIG BUCKS.
Cut of and replace you old terminals and consider replacing your battery, if it is leaking it is about to die.

 

Thanks alot!! I went down to the local autoparts store and got some new terminals. However, I just want to make sure of something. I had the parts counter worker come out and look under the hood with me in order to pick the right terminals and I asked him if it is okay to splice the two positive terminal wires together and he said it was fine. To explain, on the factory connector two wires come into the housing so there is two ports on the connector. However, on the new connectors there is only one port, so the two positive wires have to be spliced together before entering the terminal. Is this okay to do? I appreciate the help.

Ohh and Mike, I just replaced the battery that is how I realised the problem.

 

it's fine, there is no difference whatsoever...aside from former being prettier.

If you were looking to make it as nice as possible, you may want to get a soldering iron and "TIN" the ends of the wires after you strip the insulator off. You could join the smaller wires into the bundle by soldering before clamping it into the new connector. From there I'd recommend hitting it with some heat-shrink tubing just to keep it nice.If you decide not to solder the smaller wires onto the main lead, they are going to have the tendency of wanting to pull out. If you can bundle them in some shrink tubing I think it will help you out considerably.

At the very least, the ugly way of doing it would be to wrap it nicely with some electrical tape.

HTH.
