DESCRIPTION
MEMOR
RECALL
No
Accelerator input voltage too low on power up after initial
key switch closure.
CIRCUIT
Traction
SYMPTOM
Forward or reverse contactor does not pick up.
POSSIBLE CAUSE
Accelerator input mis-adjusted or defective.
* Input voltage at TB1 should be more than 3.0 volts. Adjust
or replace accelerator unit to insure that the voltage at TB1
is more than 3.0 bolts before depressing pedal.
Short circuit between battery negative and TB1 in accelerator input
circuit.
* Disconnect wire from TB1. Check for short circuit from wire
to battery negative. Resistance should be greater than 4.7K
ohms.
Defective card
* Disconnect wire from TB1. Measure voltage from TB1 to
negative. Voltage should be greater than 4.5 volts, if not
replace card.
Figure 1.
STATUS INDICATION CRITERIA
This status code will be displayed when the
accelerator input voltage at TB1 is less than 3.0
volts, and any of the following connections are
opened and closed, battery plug, foot switch or
key switch.
STATUS CODE

RECALL
No
Both forward and reverse directional switches are closed
at the same time.
CIRCUIT

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 TB5 and/or TB6.
* Disconnect wires from TB5 and TB6 and check wires for
short circuit to positive side of directional switch.
Defective card.
* Disconnect wires and measure voltage at TB5 and TB6.
Voltage should be less than 60% of battery volts.
Figure 1.
STATUS INDICATION CRITERIA
This status code will be displayed when TB5 and
TB6 are greater than 60% of battery volts at the
same time.
