I have a lift that the backup alarm all of the sudden started beeping in forward and reverse. We installed a backup light sometime ago and everything was good. Push the handle forward, you go forward. Pull the handle back, the backup light and horn both come on and you go back. Now for some reason out of the blue no matter if your driving forward or in reverse both the light and the horn come on and stay on unless the handle is in the neutral spot. No codes are being thrown. Can someone help me with this?
