I don't have a diagram but I have that same motor disassembled in boxes in my shop. What do you need to know?

I concur with Clanton. I had an overheat problem that set off the alarm and put the motor in S.L.O.W. mode yet I wasn't overheating. I did all the bulletins that Clanton posted and haven't had a problem in a year! Don't assume because you didn't have an overheat alarm go off that it's not overheating or that your not going into S.L.O.W. mode, your alarm may not be working. Do the bulletins.
