STATUS CODE
Start switch closed on power up after initial

key switch closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.

POSSIBLE CAUSE
Start switch is mis-adjusted or defective.
Traction
•=
Controller
Short circuit between P15 and P3 in start switch
input circuit.

TRACTION
STATUS CODE
Battery voltage is too low at initial key switch
-15
closure.
MEMORY RECALL
NO
SYMPTOM
Control will not operate.
Circuits valid
for
POSSIBLE CAUSE
Discharged battery
Traction
•= Check battery voltage to confirm that it is a minimum
Controller
of 68.3 volts. Charge battery, if required.
Defective battery
•= Check each battery cell for proper voltage (greater
than 1.95 volts at cell). Replace or repair battery.
Incorrect control card adjustment.
•= Check Function 15 for proper adjustment for battery
being used. See Handset instruction sheet for
details. Adjust to proper settings.
Check "minimum" battery volts at P1 & NEG.
DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
Input voltage at P3 should be less than 50%
of battery volts at key 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.
Disconnect wire from P3. Check for short
circuit from this wire to 12V positive.
Resistance should be greater than 4.7K
ohms.
Disconnect wire from P3. Measure voltage
from P3 to negative. Voltage should be zero.
If not, replace the control.
DESCRIPTION OF STATUS
CORRECTIVE ACTIONS
CAUSE OF STATUS INDICATION
This status code will be displayed when P3 is
greater than 50% of battery volts when the key
switch is closed.
