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 >0.9V when the
battery plug or key switch is opened and closed.
MEMORY RECALL
NO
CORRECTIVE ACTIONS TROUBLE-SHOOTING DIAGRAM
Circuits valid
for
Traction
Controller
SYMPTOM
Control will not operate
POSSIBLE CAUSE
Accelerator input is mis-adjusted or
defective.
•
=
Input voltage at P7 should be less than
0.9 volts. Adjust or replace accelerator
unit to insure that the voltage at P7 is
less than 0.9 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.

STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION

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.
