5.4 Troubleshooting with the Flashing Indicator Light
The status indicator light on the Control Switch inside the generator set flashes the diagnostic
fault code when a fault shutdown occurs. For a single-digit fault code (2 or 4), the light will flash
2 or 4 times and after a short pause will repeat.
For a two-digit fault code the light will flash the tens digit, pause and flash the units digit and
repeat after a longer pause. Fault 36 would be flashed as follows:
flash-flash-flash—pause —flash-flash-flash-flash-flash-flash—long pause —repeat
