I have a 2002 Mustang 2070. When I release the parking switch I get power to the entire tractor but the parking brake will not release. The bucket has full power but whenever i try to move the tractor it dies. I have replaced the parking rocker switch and have jumped the timer using the two orange wires. I have also swapped the relays in the back with no change. I cant find an operators manual or an wiring schematic. if anyone has any ideas i would appreciate it.
