Went to put trike into reverse last night after dinner and nothing happened. The reverse light came on and I could hear electrical motor sounds but no gear meshing. It was as though the switch was dead. Trike started fine and all other features seemed to work. The only thing I've done recently was drain and change the coolent last week. Could I have screwed somthig when I pulled the right pocket out to get to the radiator cap? How should I start to track this problem down? All thoughts appreciated........Alan 05 Wing with 09 Motor Trike Kit.
