Getting battery corrosion on battery wire, will this cause a problem? Is this wire replaceable?

 

Clean it with Coke and wire brush. Take it off clean the post. You are back in business

 

Sulphate crystals on the negative battery terminal will dissolve away just by spraying them with water from a bottle. The fact that they're accumulating indicates that the battery is undercharged so you may want to place it on a trickle charger.

 

Your corrosion is still minimal, but in time, it can completely dissolve ALL the copper in those skinny wires, to a point where adequate starting current can no longer flow through the cable. Often, the cable insulation extends tightly all the way to the terminal, making the corrosion, if present, not visible.

Any wire or cable can be replaced by someone of competency to do it. I use welding cable for my replacement battery cables; it is highly flexible, has good insulation properties, and is available in sufficiently large diameter to handle the heavy current involved.

 

I am under the impression that almost all corrosion of lead-acid battery terminals and cables is due to acid fumes (H2SO4) combining with the metals used in them, primarily copper, causing the greenish-blue corrosion of copper sulfate. So, yes, sulfate is a culprit. My belief is preventing it in the first place is a good approach. I coat the battery posts, terminals, and exposed conductor of cables with high-grade lubricating grease, vaseline works well, when installing them. Such treatment will prevent acid deterioration for several years.

 

good old Coke Cola is best cleaner

 

Thanks all, should i strip the wire tape to clean the inside too? That is what im worried about the most.

 

If it were mine, I would replace the cable entirely; then you can "sleep on it". The other, too, if deteriorated.

 

I checked on fordparts and it seems the battery cable is part of the starter cable harness.

Just changing the battery wire cable is out of the question, i guess ill have to strip the tape and wire wrap to get a good cleaning of the copper wires. Since there are some many tiny metal wires strands im thinking about just dipping it in baking soda to get every corrosion out. After it is cleanen i can spray it down with battery corrosion protectant spray then wrap it up again. Is this a good method? btw do i use electrical tape to tape it back up again? what kind of tape does oem use?

 

Disconnect the faulty cable at both it's ends and cut them off, tape over the exposed wire, and simply replace with new cable, attaching additional terminals if needed for supplying power to accessories.
