POSSIBLE CAUSE

Traction

Forward or reverse directional switch welded

closed or mis-adjusted to be held closed.

Controller

Replace or adjust directional switches to

 

insure that they 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 60% of battery volts.

CAUSE OF STATUS INDICATION

This status code will be displayed when P4 and P5 are greater than 60% of battery volts at the same time.
