We just got a used Precor C964i that my wife knows worked fine in the recent past. We have the 240V version and we had an electrician come out and install a 220 outlet. When we try to turn the treadmill on, some kind of protective circuit shuts it off immediately. A different electrician came out today and said the outlet is fine and there must be some kind of problem with the treadmill. Anything I might try on my own to remedy the situation?
