I have a couple of wiper motors that I am testing out. I know one is a 2 speed and I thought the other was a single although they look the same. The 2 speed worked great in the car. Question is how do I test for the second speed. Have gotten them to work as a single but not sure on what prongs to be touching to get 2 speed. Tried touching a couple at a time with the positive but still just worked as a single. Have the ground on the single by itself. Need some electrical advice, dangerous for a carpenter to be messing with electricity, lucky it is not high voltage.
My 2 speed is different. Operates off ground attached to the terminals. Top one is fast. Middle is slow. Its shaped more like a square. Mine is a 1965 unit.
