Joystick Switches Work But Do Not Light Up
-"ENABLE", "UP", "DOWN", steering LED’s do not light up, but the
functionality is fine.
1. "ENABLE", "UP", "DOWN" switches work but the bulbs inside the
switches won't turn ON possibly because of internal bulbs being
blown or the wiring to the bulb may be loose.
2. Steering angle LED display won't turn ON due to possible following
reasons:
a. Blown LED's (very unlikely that all LED's are blown), if
none turn ON, the joystick may not be providing proper
signal.
b. Faulty wiring between the LED board and the joystick board
or a loose connection.
c. The wiring between the steering angle sensor to the main
controller (Steering IN) may be faulty.
