STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-09
Both the forward and reverse switches are
closed at the same time. This status code will be displayed when P4 and
P5 are greater than 50% of battery volts.

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 are 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 50% of
battery volts, if not, replace control.

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Start switch is mis-adjusted or defective.
•
Input voltage at P3 should be less than 50%
of battery volts at key or tow switch closure.
Adjust or replace accelerator unit to insure
that the voltage at P3 is less than 50% of
battery volts before closing the start switch.
Short circuit between battery positive and P3.
•
Verify continuity of wiring at both points.
Defective control.
• Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero.
If not, replace the control.
