Problem

From the period of May 2004 through December 2004, incorrect SENS Battery Chargers may have been installed on Griffin-packaged engine generator sets.

Orders requiring a 120 VDC, 60 Hz, UL Listed battery charger with alarms (Caterpillar part number: 118-4304 Battery Charger, SENS part number: FC24-10-2011U) may have received a 230 VDC, 50/60 Hz Battery Charger with alarms (Caterpillar part number: 119-8978 Battery Charger, SENS part number: FCA24-10-44115). The Griffin-installed battery charger (119-8978 Battery Charger) is not UL Listed.

There is no known immediate danger associated with operating the 230 VDC, 50/60 Hz Battery Charger ( 119-8978 Battery Charger ) with a 120 VDC, 60 Hz source. However, if the charger was not field configured for the proper line voltage, the charger may not operate properly.

Solution

Affected 3306, 3406 & G3406 packages must have the battery charger replaced. Dealers should order 118-4304 Battery Charger from Morton Parts.
