Reply to "Fastrak switch track"

The simple way to troubleshoot is to substitute another (working) remote controller and see if both colors work.

The yellow wire from the track switch is either +5VDC or -5VDC with-respect-to-ground (the black wire) and there are diodes in front of the green and red LEDs in the controller such that + lights one pair of LEDs and - lights the other color LEDs. Thus, either the diode in front of the red LED has failed or the board in the track switch has failed.
