This is the Logic Control Unit for the alarm module that sits behind the control panel. This unit controls the alarms and monitors the alternator voltage. It controls part of the charging system that operates the Alternator and maybe the item at fault if the alternator alarm illuminates, but the batteries are charging. This new design uses LED's and not the older style that used bulbs.
