If I remember correct, this caused the starter to overheat and go bad. I replaced three lifetime warranty starters before we found the real problem.....sorry NAPA.
I've heard of this also but usually on vehicles that have had bad maintenance and the starter was used for long periods of cranking due to bad ignition,timing issues,bad gas etc.My Jeep was bought new and is meticulously maintained and starts with the flick of the wrist.The old starter with 260,000km works perfect. Wouldn't a narrow gauge positive wire, due to interior corrosion, affect the older starter with more severity? But you know anything and everything is possible in the automotive repair field and I'll check it out.
