I am slowing down and dropping the brake circuit yes. It is an AC Motor. We have not done a full load test at this point. I did notice that we loose the "D" contactor and the "U" contactor picks up. On our next visit we will check with an Analog Amp Meter. I did notice that one of the rings on the end of the motor were the brushes are appears to be badly burnt /worn different that the others. No changes have been made to the DBG on the rails.
