TRACTION
STATUS CODE
Start switch closed on power up after
-11
initial key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
for POSSIBLE CAUSE
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.
Defective control.
= Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero,
if not, replace control.
