I just bought a 1992 Marathon with Curtis controller, kids have buggered up the wiring. I think everything is hooked up except the small wires next to the on/off switch. When I turn the ign. to "on", I hear a clicking. Cart doesn't move when pedal is depressed. I downloaded the schematics, but it's not very clear. Green to on/ off switch White to negative bat. Fine black to ? red to positive Any help would be very appreciated.
