I hooked one of these to a new Newport Vessels trolling motor, 48 amp max draw, protected by a 50 amp breaker. It quit working and started smoking. It also took out the battery meter on the trolling motor, but otherwise the trolling motor still works and still gets power through the devise, but the variable speed does not work.
The description of the PWM is DC10-55V 12V 24V 36V 60A Reversible PWM Motor Speed Controller Switch
What went wrong?
