TROUBLESHOOTING
CONTROL TEST – HAND-HELD OR SOLENOID CONTROL
1. Disconnect the control in the cab and remove to
the work bench.
2. Refer to the 6-pin connector diagram and the
table.
3. Using a 12V power source with a 6 amp fuse in
the positive lead, carefully apply +12V to pin #1
and ground to pin #3 of the 6-pin connector.
4. Turn the control ON. Power indicator lamp
should be lit. Using a grounded test light, check
for 12V at each of pins #2, 4, 5, 6 when the
control is activated for each function. Footnotes
in the table indicate special conditions of control
operation.
5. Compare the control outputs for all functions
with the table and proceed to the flow chart on
the following page.
Pin # Purpose Angle R (c) Angle L (c) Raise (d) Lower/Float (e)
1 12V input
2 S2 output (3-way) ON ON
3 Ground
4 Motor relay output ON (b) ON (b) ON (b)
5 S3 output (4-way) ON ON
6 S1 output (2-way) (a) (a) ON
a. S1 output will be ON if control is in Float. Activate Raise function to cancel Float. If hand-held control is in Float,
S1 output will turn OFF while angle button is pressed and ON when the button is released.
b. For hand-held control, motor relay output turns OFF before solenoid coil outputs when button is released.
c. For hand-held control, outputs turn OFF after button is held for approximately 9.6 seconds.
d. For hand-held control, outputs turn OFF after button is held for approximately 4.8 seconds.
e. Solenoid control activates S1 output in Float when lever is moved to lower position. Hand-held control activates
Float when lower button is held for .75 second.
