Minn Kota Endura Max 55

I need a little help in diagnosing my tiller electric trolling motor. With the handle retraced all the way in the motor runs fine in forward and reverse. When I pull the handle out it runs fine in forward and will barely go in reverse and won’t shut off. I took the head off and the wiring looks fine. Any help would be appreciated.

With the cover off. Move the handle till it doesn’t work. Then move wires and connections to see if it comes on. Loose or corroded connection or bad wire would be 2 suspects. If you telescope it in and out a lot, it could have broken a wire inside the insulation. Good luck.
