Testing 1969 Power Window Motor

[mike337]

I am rebuilding my 69 Charger, I have power windows, and want to test the motors before I install them.  Can anyone tell me if the two leads on the connector are both positive (window up/window down) and the motor is grounded through the mount to the body, or is the negative connection through one of the connector leads?

You can test it on a battery, touch it on the posts and it should spin one direction, reverse polarity to make it spin the opposite direction.

So connect the positive to one of the connector plugs spade terminals, and the negative to the other?  Trying to make sure I don't toast a motor.

It makes no difference which way its connected (for testing purposes anyways). Connected one way the motor will turn in one direction, connected reversed it will spin the oppisite direction.

Agree. Easy to bench test. Just need a battery and two wires.

Yup, the polarity is reversed in the switches.

You can test with some jumpers and a battery, but do test both directions. If the brushes are badly worn it may work much better one direction than the other.
