Thats an interesting approach Jared. I wonder how many starters have been replaced due to contact resistance on starter side? I would expect that type of failure to be characterized more by a slow degradation of cranking power - starter cranking slower over time. That is certainly a common complaint on these cars that most of us assume is failing bearings on the starter. Cleaning up the contacts might be a good plan to delay the inevitable replacement of a starter.

In this case though contact resistance on the solenoid supply side is a more probable explanation of the intermittent starting. Seems like that resistance was up in the switch - again a high probability culprit.

I'm a strong believer in a volt meter for this type of trouble shooting. If you don't have the full 12 volts at the terminal - trace it back.
