New to this site and looking for a little help on diagnosing a problem with new stop arm motors burning out. I replaced a stop arm motor because it was seized and came to the conclusion that it seized because it wasnt turning off when its susposed to. I replaced this motor with a new one, well the stop sign closes when I put power to it with the key off but why doesnt the motor stop when it reaches the side of the bus? I also replaced the elec module that senses position of the motor and it makes no difference. All power is there, grounds are good, the 8-way switch on steering wheel works, Just motor stays on and will not quit until it burns out. Any advice or helpful hints would be really apretiated.
Newer maxxforce 7 IC bus.
