5. The "INPUTS DISPLAYED" LED, on lower right col-
umn of the Diagnostic Display, should be illuminated. If
the green "OUTPUTS DISPLAYED" LED is illuminated,
press the toggle button on the Diagnostic Display to
change to "INPUTS DISPLAYED" LED.
6. The Diagnostic Display will illuminate the LED
associated with each of the inputs when that input is in
the position identified on the Diagnostic Display overlay.
Individually, change the position of each of the inputs
(i.e. sit on seat, move joystick, etc.), and note that the ap-
propriate LED on the Diagnostic Display toggles on and
off when the input state is changed (see Diagnostic Dis-
play Inputs and LED Operation chart on next page). Re-
peat for all inputs that can be changed by hand.
7. If appropriate LED does not toggle on and off when
input state is changed, check all wiring and connections
to the switch for that input and/or test switch (see Com-
ponent Testing in this chapter). Replace all defective
switches and repair any damaged wiring.
Greensmaster 3300/3400
NOTE: The LEAK DETECTOR controller input is only
used on Greensmaster 3300 machines. The COOLANT
TEMP and ALT FAULT controller inputs are only used on
Greensmaster 3400 machines. The HYD TEMP control-
ler input is only used on Greensmaster 3400 machines
equipped with the optional hydraulic oil cooler. The
ELECTRIC REEL SPEED controller input is not used on
Greensmaster 3300 or 3400 machines.
NOTE: On Greensmaster 3400 machines, the ALT
FAULT controller input cannot be reliably tested by
grounding the harness leads at the alternator. If the al-
ternator is faulty, a TEC controller fault should have
been detected. Refer to Diagnostic Light in this section
for information on retrieval and clearing of TEC control-
ler faults.
NOTE: When the ignition switch is in the OFF position,
all Diagnostic Display LED's should be OFF.
8. After input function testing is completed, disconnect
the Diagnostic Display from wire harness. Plug loop-
back connector into wire harness connector. Install right
side cover next to operator seat.
