TRACTION	DESCRIPTION OF STATUS
STATUS CODE
-51	Capacitor volts are low before the line
	contactor closes.
MEMORY RECALL	CORRECTIVE ACTIONS
NO
	SYMPTOM
Circuits valid	Line contactor does not close when capacitor
	does not precharge.

Defective control.

•Replace controller unit.

CAUSE OF STATUS INDICATION

This status code will be displayed during “key on” when the capacitor voltage is less than 85% of battery volts at initial key switch on.
