Thanks Richard, this is proving very helpful. I thought I had a lead on a new old stock replacement, but it's taller and draws slightly more current. Which isn't a wanted, considering those control boards. I'm going to go back to hangar and try 115v right at compressor and clamp on amp meter it. Perhaps it's not a locked or sticky rotor, instead being a relay or connections with resistance. Compressor comes on line, condenser fan comes on, line voltage starts at 120v then drops to 93v in 2-3 seconds and an internal breaker in compressor takes compressor out of circuit. Comprssor internal Breaker cools and cycle starts again. I can't get to it until next week though. I had thought I had lost the compressor when it blew a serious hole in the condenser coil and lots of oil was lost. I don't think there is a Freon low pressure switch in these units, so it ran awhile before we noticed cooling was lost.
