hey guys. I just had 12 mid 70s Montgomery tractions added to my route. all have mg control with relay logic controllers and a damper motor for shunting. ive got a couple that are going into the top over travel. ive replaced a few of the relays and changed a few brushes. it lands at floors dead on and the brake seems to be dropping fine. any suggestions of what else I could be looking at would greatly help. thanks
