Four-Position
Isolator System.
Because of the elec-
trical requirements
to enjoy the boat in
its fullest experience,
most models are
equipped with two (2)
batteries. The optional
battery ON-OFF switch
is located in a panel
behind a door on the
port side of the walk-through between the bow and center deck.
(The numbers 1, 1+2, and 2 refer to the two batteries that you purchase for the boat. The batteries are located
in battery holders in the bow. As part of the routine maintenance, boat owners should routinely verify that the
batteries are secure within the holders.)
There are four markings on the knob:
• OFF
• 1
• 1 + 2
• 2
OFF means that all power to the battery is shut down. The battery will not be able to re-charge while in the
OFF position. This is the appropriate setting for periods of inactivity with the boat. When the boat remains in the
water, the bilge pumps will still be powered by the battery in case it becomes necessary for the bilge pumps to
turn ON to periodically and automatically pump out residual water in the bilge system. See above description of
how the bilge system operates automatically.
Battery 1 is the starting battery or main battery. It should be rated at least 800 cold cranking amps (cca), and
a spiral cell battery is preferable. Battery 2 is the “house” battery (used to run the electronics, a smaller 500 cca
battery is acceptable).
Normally, the switch should be set on 1+2 when the boat is running to charge house battery, but when
listening to music without the engine running, set it at 2 so the starting battery is not drained. When the battery
switch is not turned to OFF, it should be set on 1.
If battery 1 is somewhat drained or sluggish, turning to “1+2” can be very helpful in providing sufficient pow -
er to start the engine and begin the natural recharging process.
All systems:
If the battery has insufficient charge, use only a battery charger to recharge the battery, or
remove the battery and take it to an authorized dealer or auto parts store that has the appropriate facilities to
safely recharge the battery. If the boat is out of the water and/or in storage, OFF is the setting for the battery
switch.
Malibu does not recommend the purchase and use of battery chargers other than the battery charger offered
as an option through your authorized dealer. The battery charger offered by your dealer has been selected as
best for meeting the requirements of 800 cca batteries.
If a battery(ies) requires a jump start, do not allow the alternator to
recharge it/them as it can lead to the alternator failing much more quickly
than it would normally. Such damage would not be covered under warranty.
