[Roadsters] windshield wiper motor

[garytew at cox.net]

I put juice to the roadster this week to start testing circuits and verify my wiring.  The wiper motor did not work.  I got under the dash and pulled one of the wiper arms and the motor ran for a second or 2.  I haven't done anything since.  My plan is to pull and bench test it and also check for any binding.  Are there any issues I should know about on these motors?  Also, I pulled one from my parts car ('65) and it has a wiring harness plug in the end of it with 4 posts while my ('67) motor has 5 wires coming out of it.  Anyone know the wiring scheme of the 4 wire motor?  So far, no major issues on the wiring. The lights, horn, turn signals, horns, and clock all work.  Will start testing the door actuators and power window circuits next when I have time.
