I want to check the power window motor to make sure it works. It has 5 pins. One black wire, 4 orange wires with different stripes. I used a powermax jump box. Checked its output. 12.6 volts. I touched the negative off box to black pin, the positive off box to each of the 4 remaining pins. Nothing. This motor was good when taken off. Am I doing something wrong?

Thanks for any help, Kevin
