Also, even with the motor stopped, reversing it causes the 20 amp SP breaker to trip ? Before, & after the control was changed.

As a former owner of horses, I can tell you that in addition to horses liking to chew on anything, their manure and urine are highly corrosive and will rot out most anything.

Good luck!
