1. Remove both J102 (pins 1, 2, 4, and 5) of the AC driver PCB and J1 (pins 5, 7, 1, and 3) of
the Low-voltage Power Supply PCB.
2. Check for the harness disconnection between the corresponding pins.
• Between J102 (pin 1) and J1 (pin 5)
• Between J102 (pin 2) and J1 (pin 7)
• Between J102 (pin 4) and J1(pin 1)
• Between J102 (pin 5) and J1 (pin 3)
3. Check for short-circuit of the harness between pins other than corresponding ones.
