The wire in the car is the original that came with it. I had this problem once before and was stranded at the airport while trying to pick up my son. I only found the problem when I tried to turn over the car with the cap off and saw sparks in the wire.
I tried getting a new one at Napa when it happened but they did not carry one so I fixed the old one. I will try again to get a new one.
What really is a zero resistance wire? Is that possible?
