Coach Batteries
The coach batteries in your Carado are either sealed AGM batteries or optional Lithium Battery cells.
DO NOT ATTEMPT TO OPEN THEM
! There
is no user maintenance needed on these batteries.
*Tampering with your batteries will void the Carado warranty on them.*
Plug your coach in
to external shore power whenever possible to ensure your coach batteries are in a fully charged state.
Battery Disconnect Switch
The battery disconnect switch provides power to all 12-volt appliances, such as the lights, water pump,
the refrigerator, and so forth. This switch should be off when you are not using your Carado, and on
whenever you are driving or camping. (Picture 48.1)
Inverter Charger
Your Carado is equipped with a 2000-watt inverter-charger which converts 120-volt AC (household
current) to 12-volt DC when you are connected to shore power or running the standard underhood
generator. This 120-volt power is used to power your 12-volt DC appliances as well as charge your
batteries. Whenever you are receiving either source of 120-volt power, you are charging your batteries.
(See page 49 for Inverter Location and Image)
Alternator Charger and Battery Isolator
While driving, your Carado will also charge the coach batteries from the vehicle's alternator through an isolator. The isolator allows extra vehicle
alternator-produced electricity to charge your coach batteries in addition to keeping your engine (chassis) battery charged. When the vehicle engine
is not running, it breaks the electrical connection between your coach batteries and your engine battery, so your engine battery remains charged to
start your engine even though you are using coach battery power while camped. This is all automatic - there are no user adjustments needed for the
isolator. *If you have the optional Lithium Battery system, you should drive with your batteries in the on position. (Press the reset buttons one time
as well). The lithium batteries need to be in the on position to accept a charge while driving and should ensure your batteries will be fully charged
when you reach your destination.* *For AGM batteries, your battery disconnect switch on the monitor panel needs to be in the on position.*
