I think my cables might still be ok, just that replaceing them might be good, since they are 25 years old. About a month ago, I noticed that the insolation had shunk at the ends, and there was some corosion on the copper stands, so I cleaned it up as best as I could and wrapped them with electrical tape. They seem to be still be doing the job ok, but after I replace the starter and it still cranks slow, then I might go ahead and replace them. Those Diamondback Alloy-Shielded Battery Cables are $16 for the negative cable, and $18 for the positive cable.
