TRACTION DESCRIPTION OF STATUS
STATUS CODE
Both the forward and reverse switches
-09
are closed at the same time.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.

for
POSSIBLE CAUSE
Accelerator pedal is depressed before
Traction
closing forward or reverse directional
Controller
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.

shown in Trouble Shooting Diagram.
TRACTION
DESCRIPTION OF STATUS
STATUS CODE
Start switch closed on power up after initial
-11
key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
for
POSSIBLE CAUSE
Traction Start switch is mis-adjusted or defective.
•=
Input voltage at P3 should be less than
Controller
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.
