I have a 69 Barracuda 2 speed wiper motor that has been sitting on a shelf for a long time. I would like to test it, but I am not sure how. i am pretty good with electric systems, but I can't figure this out. If it works, I'll probably clean/powder coat it and sell it. PS New avatar is my wife helping me strip the paint off the Barracuda a few years ago. She's a keeper. Thanks.
