STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-09
Both the forward and reverse switches
are closed at the same time.
This status code will be displayed when P4 and P5
are less than 7.2 volts, and P7 is less than 2.5 volts.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Accelerator pedal is depressed before
closing forward or reverse directional
switch.
•
=
Status code will disappear when
directional switch is closed or when
accelerator pedal is released.
Defective directional switch
•
=
Check forward or reverse switch to insure
closure when direction is selected.
Open circuit between directional switch(es)
and 12V positive or between directional
switch(es) and P4 or P5.
•
=
Check all control wires and connections
shown in Trouble Shooting Diagram.

STATUS CODE
DESCRIPTION OF STATUS
CAUSE OF STATUS INDICATION
-11
Start switch closed on power up after
initial key switch closure.
This status code will be displayed when P3 is greater
than 7.2V when the key switch is closed.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Start switch is mis-adjusted or defective.
•
=
Input voltage at P3 should be less
than 7.2V at key switch closure.
Adjust or replace accelerator unit to
insure that the voltage at P3 is less
than 7.2V before closing the start
switch.
Short circuit between P15 and P3 in start
switch input circuit.
•
=
Disconnect wire from P3. Check for
short circuit from this wire to 12V
positive. Resistance should be
greater than 4.7K ohms.
Defective control.
•
=
Disconnect wire from P3. Measure
voltage from P3 to negative. Voltage
should be zero. If not, replace the
control.
