After posting this question, I started reading some other similar posts. The one thing that kept coming up was trouble with the solenoid on the driver's side. I followed the directions for testing the solenoid. First I checked for 36v at the small terminals. I did get 36v there. Then with the pedal depressed I checked for continuity between the large posts on the solenoid. No continuity. Then I jumped the solenoid with a large gauge jumper and The cart moved!
I haven't checked the other solenoids yet, but I think this is where the problem lies. The motor definitely works, and the F/R switch works. Now as you guys said, it's either a micro switch or 1 or more solenoids.
I did buy a new prestolite solenoid on ebay for $18.50 plus shipping.
