The PORT engine is equipped with an alternator that charges the 12-volt accessory battery bank . The DC equipment will eventually
drain the batteries being used without the PORT engine running .
IF THE bATTERIES GET DRAINED
, either:
Start the PORT engine or use the onboard battery chargers to recharge the batteries .

•
A 100 amp battery charger monitors the voltage levels of the accessory batteries
•
An additional 100 Inverter/Charger monitors the voltage levels of the accessory batteries
•
Each charger monitors and maintains the voltage levels of one or more batteries . When the chargers are ON, they automatically
