Can you tell me what HP the DC motor is. I just had mine re-worked and the prolem I'm having is the spindle keeps shutting down in the middle of a cycle run. I just purchased a 7.5 HP phase converter and still having the problem, also the phase guy wanted to know which leg I had the hot lead wired to (T3) I don't have a manual so can you tell me which leg is the hot one. I have a black, blue and red wires coming from the machine to the switch box mounted on the rear of the machine. Its a series II 1985 model year with the Contraves and Heildelhain controller. Any help would be greatly appreciated.
