Greetings to all. Please help if you can. I have a 2018 Mallard IDM 26. Front stab jack works fine. Rear jack will pulse while extending and will not retract at all. Used the good switch from front jack on the rear with same issues. Took motor off and seems to function normally while connected directly to a battery in both directions. With the motor off, the jack freely moves up and down manually. When it’s all put together. The wires connected to switch in the middle connectors become very warm to the touch while the button is pressed. Any ideas anyone can think of that I’ve missed? This is driving me nuts!!
