I recently bought and installed one of these. The first thing I noticed was the motor got very hot on 15, 20 mile runs.. After about 300 miles it stopped working and the autopsy show all three phase wires were charred embers and the stayer was badly charred and the motor frozen. The code was 04 motor blocked. I replaced the motor but still the same code so I'm trying to order a new controller. My question is, is there a 52V, tsdz2b controller with the OSF firmware pre-loaded? I found this but I don't need the cable or display.
