I need to change my negative battery cable. How do I do it? Do I need to get 2 or 4 gauge wire? Which is better? Please Help!

 

Are you sure you NEED TO CHANGE the cable

or do you need to just chaNge the clamp

 

I already changed the clamp and the corrosion keeps coming back! So, a friend of mine said it could be in the battery cable itself.

 

correct me if im wrong but doesnt battery cause the corrsion

you know if you just want to clean up the battery terminals

just use a little baking soda a nd water

clerans it right up

im going to look tomorrow to see how to change the cable

let you know tomoorw

unless someone already has ??

 

what year is this car ???

 

Lower the number, thicker the cable (can carry more current). So #2 would be more desireable, but what is the required gauge? ... I don't know.

Corrosion happens at the point of junction of dissimilar metals exposed to air.

Suggestion: Try getting a clamp made out of lead (to mate with lead of the post). Next get a contraption where the wire (copper) is molded inside the lead. .ie avoid the setup where you clamp down the wire and go for the wire +clamp sold as one piece.

I apply a thin coating of grease on the exposed part of the terminal and have not had any corrosion problem. [the inside of the clamp should be clean and dry to make a resistance free contact with the post.
