5. Turn the key switch to the O
not start the engine.
Note:
The red text on the overlay decal refers
to input switches and the green text refers to
outputs.
6. The "inputs displayed" LED, on the lower
right column of the Diagnostic ACE, should
be illuminated. If the "outputs displayed"
LED is illuminated, press the toggle button
on the Diagnostic ACE to change it to "inputs
displayed."
The Diagnostic ACE will illuminate the LED
associated with each of the inputs when you
close that input switch.
7. Individually change each of the switches
from open to closed (i.e., sit on seat, engage
the traction pedal, etc.), and note that the
appropriate LED on Diagnostic ACE blinks
on and off when you close the corresponding
switch. Repeat this for all switches that you can
change manually.
8. If a switch is closed and the appropriate
LED does not turn on, check all wiring and

connections to the switch and/or check the
switch with an ohm meter. Replace all switches
and repair wiring that are not functioning.
Note:
The Diagnostic ACE also has the ability to
detect which output solenoids or relays are turned
on. This is a quick way to determine the source of
the malfunction.
