The Stovebolt Site Forums The Shop Area The Electrical Bay Reverse polarity switch

I have a 41 chev pu 1/2 ton with what I believe is the orig. push starter. From what I'v read in 41 they started using a reverse polarity switch but mine does'nt have any holes in the top of the starter for it was wondering if I should go without it?

What does a reverse polarity switch do?
Thanks,

Kurt

Hy guys, the reverse polarity switch was a device the engineers came up with that was mounted on the starter, everytime you started the truck it reversed the polarity of the electricity flowing through the points. The theory was that this would cut down on metal transfer between the fixed and movable points, better condensor technology made these parts unnecessary, and they were discontinued after a couple of years. So don't bother putting one on in the first place, hope that helps.

3B is correct and Im not in front of my Delco books at present but pretty sure they were only used in like 46-47, somewhere in there. Not a necessary part unless your doing a 100% show quality restoration for that particular year model and even at that most folks dont know what they are or if they are correct or not.

Wow, I've had old Chevys for 40+ years, and never heard of that before. Gotta love this forum, I learn something every day.
