closed or mis-adjusted to be held closed.
• Replace or adjust directional switches to
Controller
insure that they open when directional switch
is returned to neutral.
Short circuit between battery positive and P4
and/or P5.
• Disconnect wires from P4 and P5 and check
wire for short circuit to positive side of
directional switch.
Defective Control
• Disconnect wires and measure voltage at P4
and P5. Voltage should be less than 60% of
battery volts.
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
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.
Defective control.
• Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero, if
not, replace control.
