POSSIBLE CAUSE

Traction

Start switch input mis-adjusted or defective.

Input voltage at P3 should be less than 60% of

battery volts at key switch closing. Adjust or

 

replace accelerator unit to insure that the

 

voltage at P3 is less than 60% of battery volts

 

before closing the start switch.

 

Short circuit between battery positive and P3 in

 

start switch input circuit.

 

Disconnect wire from P3. Check for short

 

circuit from this wire to battery positive.

Defective control.

Disconnect wire from P3. Measure voltage from P3 to negative. Voltage should be zero, if not, replace control.

CAUSE OF STATUS INDICATION

This status code will be displayed when P3 is greater than 60% of battery voltage when the key switch is closed.
