I have a issue that I still can't figure out with my convertible top. I check the wire and there are no breaks. I check the switch and it is good as well. But when I check the wires coming out of the top motor with my multimeter it started to beep when I touched the wires. I dont think that should happen because there are individual wires one to make the top go up and a wire to move the top back down. I think that there is a issue with the top motor itself. Does anyone know if this is true?
