What was the original problem with the motor? Also make sure you are getting full field voltage to the motor. You check for leaks with a megger.

Orig prob w motor is that they pulled the motor due to a broken pig tail and the com was cooked.i check the MF runs constant at a standing of 40 and running around 85 in both directions.

It’s a good idea to check neutral first. Even if the motor/gen just came from a motor shop. You’d be surprised.
