headlight motor test

[Doug L.]

My newly purchased '64 needing complete restoration has original headlight motors that don't open (bulbs and bezels missing). No telling if it is the switch, harness, motors or what. I have another pair of motors and would like to test both the motors on the car and those on the bench. Is there a simple way to test them? I don't want to apply voltage directly to a motor without some guidance on which terminal, what to expect, etc. I don't have a shop manual or wiring digram yet.

Thanks for any advice

Doug -

The round connector on the motor has two spade terminals - one is UP, and the other is DOWN, and the motor case is ground (there's a small threaded hole in the case for the ground screw when it's installed). Attach the ground wire from your power source to the motor case, and touch the +12V wire to each terminal - one should make the motor run one way, and the other terminal should make it run the other way.
