That is because you don't have to do any more.

One final update. The motor is back together, and runs but slowly. Even with all the cleaning, the disassembly and the reassembly, the new parts, brush holders (they are NOS and are made from 60 year old plastic), there is still an issue. One last thought, what if I turn the back cover 180 degrees....well as it turns out that is what I probably should have done first. It appears that the back cover was slightly off center in one direction and merely turning it 180 degrees made all the difference in the world. Why is it always the last thing you try that works?

Here is a corrected way to wire the dc motors used in window motors. Tom

Nice car, I love the 53 Mercury. It was the best looking of them all. It was also my honeymoon car.

Roy: The motor is not a permanent magnet motor and is not polarized. I must have had a brain fart when I typed in the wiring. You got the correct response, a spark, with that wiring. The motor is a series wound motor. This means that the field is in series with the brush. The configuration that I assumed that you have is that the yellow and red leads are the field leads and that the green and black are the brush leads. Try wiring it this way: first way b = + r = - g + Y second way reverse direction b = + y = - g + r Tom Tom: You are correct. I can not thank you enough. Thanks again, Roy

Try swapping the yellow and red wires. That should reverse the motor. What year Mercury are you working on? Tom
