I just noticed my front diff is not unlocking...the servo isn't driving. Swapped the receiver plug with the Rear diff servo and the front works but the rear doesn't. So I know it is either the receiver or the transmitter. When the rear servo is plugged in to the front's channel the bumper LEDs come on but the servo doesn't drive. This leaves me with 2 questions:
Is it possible to have a bad channel on the receiver that will power the LEDs but not drive the servo?
What are the odds that the transmitter isn't working to drive the front diff servo?
