The quantity of wires at the motor from the switch 4. The switch make and model That information may lead us in the right direction to determine what may the issue. Let me know and we can continue,Thanks

the old motor is gone ! the new one has BH-usa on it and the switch has BREMAS written on it
Expert:  AssuredElectrical replied 2 years ago.
Ok,The BH-usa is only the Boat House labeling, not the marathon motor information.The Bremas too is only a name, which doesn't help unfortunately for either.There are dozens of possibilities on each .Without the needed information, it isn't possible to determine anything.If you can get more, we can try from there
