STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-06
The accelerator pedal is depressed with
no direction selected. This status code will be displayed when the
accelerator voltage, at P7>1.5V, and no direction is
selected (P4 and P5 are both less than 7.2V)
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM

SYMPTOM
Control will not operate.
POSSIBLE CAUSE
Accelerator pedal is depressed before closing
forward or reverse directional switch.
•
=
Status code will disappear when
directional switch is closed or when
accelerator pedal is released.
Defective directional switch
•
=
Check forward or reverse switch to insure
closure when direction is selected.
Open circuit between directional switch(es)
and 12V positive or between directional
switch(es) and P4 or P5.
• =
Check all control wires and connections
shown in trouble shooting diagram.

STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-08
Accelerator voltage input is too high on
power up after initial key switch
closure. This status code will be displayed when the
accelerator input voltage at P7 >1.24V and either the
battery plug or key switch is opened and closed.
MEMORY RECALL
NO

SYMPTOM
Control will not operate
POSSIBLE CAUSE
Accelerator input is mis-adjusted or
defective.
• =
Input voltage at P7 should be less than
1.24 volts. Adjust or replace accelerator
unit to insure that the voltage at P7 is
less than 1.24 volts before depressing
pedal.
Disconnect wire from P7. Check for short
circuit from wire to P15. Resistance should
be greater than 3.5K ohms.
Open circuit at P8 or open potentiometer
wiper at P7 – verify continuity of wiring at
both points.
