STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-09
Both the forward and reverse
directional switches are closed at the
same time.
This status code will be displayed when P4 and P5
are greater than 60% of battery volts at the same
time.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Forward or reverse directional switch welded
closed or mis-adjusted to be held closed.
· Replace or adjust directional switches to
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

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Start switch input mis-adjusted or defective.
· Input voltage at P3 should be less than 60% of
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.
