Anyone have any idea what the system is looking for in a Forestry door that keeps the Mulcher from running? I have an aftermarket forestry door and am told the Bobcat Forestry Mulcher will only work with a Bobcat brand door? There are only 3 wiring connections to any of the doors, one goes to a dry normally closed set of contacts (the door latch), one goes to the windshield wiper motor, and the last on goes to the windshield washer pump. none of the seem to go to the attachment harness. Also, when I start the machine, the high flow light automatically comes on?
