until spring in pump assembly releases. Operate pump
up and down until a solid stream of fuel flows out
around filter plug and tighten plug.
3. Loosen the air vent plug on the fuel filter/water
separator about 1-1/2 turns (Fig. 27). Operate priming
pump until solid stream of fuel flows from the vent hole
(Fig. 27), then tighten air vent plug.

Diagnostic Light
The machine is equipped with a diagnostic light which
indicates if the electronic controller is functioning correctly.
The green diagnostic light is located under the control
panel (Fig. 28). When the electronic controller is
functioning correctly and the key switch is moved to the
ON position, the controller diagnostic light will be
illuminated. The light will blink if the controller detects a
malfunction in the electrical system. The light will stop
blinking and automatically reset when the key switch is
turned to the OFF position.

1. Electronic controller light
When the controller diagnostic light blinks, one of the
following outputs has been detected in the controller:
• One of the outputs has been shorted.
• One of the outputs is open circuited.
Using the diagnostic display, determine which output is
malfunctioning; refer to Checking the Interlock Switches,
page 29.
If the diagnostic light is not illuminated when the key
switch is in the ON position, this indicates that the
electronic controller is not operating. Possible causes are:
• Loopback is not connected.
• Fuses are blown.
• The light is burned out.
• Not functioning correctly.
• Fusible links are blown.
Check electrical connections, input fuses and diagnostic
light bulb to determine malfunction. Make sure loopback
connector is secured to wire harness connector.
Note: If the diagnostic light flashes during normal
operation of the machine, do not turn off the machine,
toggle to the output and touch any switch. The LED will
flash indicating the source of the failure.
