DESCRIPTION OF STATUS
STATUS CODE
Start switch closed on power up after
-11
initial key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
POSSIBLE CAUSE
for
Start switch input mis-adjusted or defective.
Traction
•= Input voltage at P3 should be less than 60% of
Controller
battery volts at key switch closing. Adjust or
replace accelerator unit to insure that the
voltage at P3 is less than 60% of battery volts
before closing the start switch.
Short circuit between battery positive and P3 in
start switch input circuit.
•= Disconnect wire from P3. Check for short
circuit from this wire to battery 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 control.
TRACTION DESCRIPTION OF STATUS
STATUS CODE
Steer angle potentiometer voltage is
-12
too low.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
POSSIBLE CAUSE
for
Steer angle potentiometer input mis-adjusted or
Traction
defective. Loose or missing connections at P19,
Controller P12 or P20.
•= Input voltage at P12 should be greater than
.30 volts at all times. Insure that the
adjustment of the steer potentiometer is in
accordance with Section 9 of this instruction.
Defective control.
•= Replace controller unit.
