I have an electric lift that goes only one way and the other way it kills the engine. I installed a new lift switch but it still fails. I had the covers off and it worked for awhile. Put everything together and it still worked a few times. Started moving the mower forward and now it doesn't work. I'm guessing some type of short. With the current wiring, it will lift up but when you try to lift down, you hear a click and then everything was dead. Is there another relay that can be replaced? Thanks.
