Well, when I got home today, there was a serious stench of a very angry electrical God (Zeus??). The controller, the most expensive part at $75, was stone cold (thank heaven), and I could see no melting wires. No smoke. I think it's the motor. I won't have a chance to look it over until spring break
Man, I guess 2 hp at 36v rating isn't supposed to lug 1,700 lbs around at 72 volts- go figure. Back to burning dead dinosaurs for a while.....
