Battery Maintenance - Malibu Boats Wakesetter 20VTX 2019 Owner's Manual

Step 1: Ensure the engine is OFF, and the Battery Switch is OFF on
boats where equipped.
Step 2: Place the batteries in the containers.
Step 3: Attach the positive cable to the secondary (2) battery,
attaching the positive (+) cable to the positive (+) post.
Step 4: Attach the positive cable to the primary (1) battery, attaching
the positive (+) cable to the positive (+) positive.
Step 5: Attach the negative (-) cable to the secondary (2) battery,
attaching the negative (-) cable to the negative (-) post.
Step 6: Attach the negative (-) cable to the primary (1) battery,
attaching the negative (1) cable to the negative (-) post.
Step 7: A separate cable is attached between the two negative (-)
posts on the (1) and (2) batteries for additional ground.
Step 8: Check that all cables are secure. Do not torque any connec-
tions; hand-tighten securely using a wrench. Never round
off any of the nuts used to secure the cables. If a nut will not
tighten, do not force it. Seek assistance to determine if the
nut is the wrong size or some other issue exists.
If a battery requires replacement, reverse the steps above. Never
replace a battery with the boat electrical system ON. Even if only one
battery requires replacement, follow the steps and disconnect/then
reconnect cables as directed above.
during installation! Never attempt to install or replace
batteries with the boat electrical system ON, or in the
presence of gas fumes. An electrical spark caused by
connection to a functional battery can cause an explosion
or fire, which is likely to cause serious injury or even
death. This can also cause substantial damage to the
electrical system, which is not covered under warranty.

Battery Maintenance

Batteries require routine maintenance to operate properly. See
the Care and Maintenance section of this Owner's Manual for details.
Battery Charger
The charger is a three-stage electronic device that operates auto-
matically when properly installed. There are red and green LED lights
on the charger face to provide evidence that charging is occurring.
When the battery or batteries are fully charged, the unit will automati-
cally shut OFF.
The charger plugs into a socket under the observer's seat. It can
be left in place without boiling electrolytes in the battery, but Malibu

recommends disconnecting and
storing it when not in use. If the
charger ever appears to be mal-
functioning, take the boat and
charger to an authorized Malibu
dealer for troubleshooting.
DO NOT USE
AUTOMOTIVE JUMPER
CABLES TO START THE
ENGINE. Never jump-start the boat from a vehicle on-
shore or another boat. The presence of water and fumes
create a situation in which sparks or backfire could result
in serious injury or even death.
Engine Sensors
To ensure the engine runs as designed, it is equipped with
several sensors that constantly monitor engine functionality. These
sensors include:
• Oil temperature sensor
• Oil pressure sensor
• Manifold absolute pressure (MAP)
• Camshaft position sensor
• Crankshaft position sensor
• Coolant temperature sensor
• Knock sensor
These sensors are inaccessible to consumers because they are
located inside sealed portions of the engine. Sophisticated, expen-
sive tools are necessary to analyze the sensor activity; therefore, if
any of the sensors indicates malfunction, the boat needs to be pre-
sented to the authorized Malibu dealer for diagnosis and resolution
of any issues that may be present. Notice of potential malfunctions
will appear on the video screen. (See Video Screen section of this
Owner's Manual for more detail.)
Additionally, alarms may sound if issues arise affecting engine
operation. These alarms may be visual on the video screen or may
be audible alarms. Although it is possible for a sensor to be in error,
it is unlikely. Experience has shown over the years that the sensors
are highly accurate and offer protective warnings of malfunction that
could potentially bring attention before more expensive and damag-
ing events occur. Never ignore an alarm! Seek assistance from your
authorized Malibu dealer if the issue cannot be resolved or recurs.
