is this the reason that the stock starter has a hard time turning the engine ?
nd,
No, I think it's the solenoid and purple wire problem. All of the heat that the starter gets pretty much ruins the solenoid, and the resistance in the solenoid purple increases. So, I guess some of the things the guys have done are to heat shield the whole mess, increase the size of the purple wire and go w a Mini-Starter like the CVR.
I've got the CVR and need to figure out how to heat shield it. Guess this belongs in the Elect section.
