STATUS CODE
DESCRIPTION OF STATUS CAUSE OF STATUS INDICATION
-76
Capacitor (1C) voltage too high. This status code will be displayed when the voltage on
the capacitor goes above limit voltage* during the
regenerative braking cycle.
MEMORY RECALL
YES

SYMPTOM
Line contactor opens and closes, then
opens and can only close by opening
and closing the key switch.
POSSIBLE CAUSE
· Unplugging the battery connector
during regenerative braking.
· Line contactor bouncing open during
regen.
· Main power fuse opening during
regen.
· Intermittent battery plug connection.
