Technical Rear window 6Vmotor test - 4 wire motor

I want to test the window motor on a 6 volt battery, off the car. The 4 leads are red, black, white and green.

Black to pos (+)

Red to neg (-)

White to ?

Green to ?

 

one set is + - for up, other set is +- for down. Experement a bit.

 

Thank you Tom from the Nation Forum of the Early Ford V8 Club for the folowing....by the way it does work:

The best way to test the motor is to hook it up to the relay and switch for window motor switch.

The wires should be color coded black, red,yellow and green.

Check this out with an ohm meter, the meter connected to the black and green wires should read around 0 ohms and not change when the motor is turned by hand, The meter connected to the red and yellow wires should read around 0 ohms but it will fluctuate when the motor is turned by hand.

first way
Black = (+)
Red = (-)
Green + Yellow

second way reverse direction
Black = (+)
Yellow = (-)
Green + Red

Tom:

Thank you that did work. I do have the relays but I wanted to be able to bench test a motor without having to pull the back seat out of the car. I have been known to cary a 6V battery to swap meets just to check items before purchase.

Thank you again,

Roy


One final update. The motor is back together, and runs but slowly. Even with all the cleaning, the dis***embly and the re***embly, 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?


Now you can test the window motors on the bench both ways with out the relays and switches!
