Electrical wiring or harness issues
should always be addressed by an
authorized Malibu dealer. Alteration
of wiring from the original Malibu design could result in shock
hazard, potential spark that could lead to fire. Any disruption of
the wiring from its original plan and resultant damage to com-
ponents or the boat is not covered under warranty. Individuals
could also be injured by such error.

BASIC ELECTRICAL COMPONENTS
Circuit Breakers
All major boat circuits are protected from shorting and overload
by resettable circuit breakers. If a circuit breaker becomes tripped,
you should turn the battery isolator switch to the OFF position as
soon as possible then wait about one (1) minute before resetting the
breaker and turning the battery switch back ON. If the circuit contin-
ues to trip, there is a problem somewhere in the system. Take your
boat to an authorized Malibu dealer to locate and safely correct the
issue.
There are three breaker panel locations in all Wakesetter and
M-Series boat models, and two panel locations in Response TXi
models. Each location is responsible for different areas of the boat
and are shown in the following figures.
Driver’s Helm:
Under OB seat:
Port rear storage compartment:
Power Wedge III, Surf Gate, and Stern Turn (if equipped) breakers
are located on the board in the port rear closeout adjacent to the
engine compartment. If any of these systems will not operate, ver-
ify that the supplemental breakers located in the port rear storage
compartment are properly set.
If a circuit breaker continues to trip, do not hold the breaker in posi-
tion to activate the electrical circuit. See an authorized Malibu deal-
er immediately to locate and correct the issue before operating the
boat.
Engine Fuse Box
In addition to the circuit breakers that con-
trol most of the electrical activity on the
boat, Malibu engines also have a fuse box
on the engine.
This fuse box aids in controlling various
electronic functionality within the engine.
Its purpose is to prevent electrical over-
load to various key electronic elements. If
the fuse “kicks” off, it tends to be a signal
that certain vital operations have experi-
enced an electrical surge that could have
caused significant damage to the system if
the fuse had not blown.
The fuse box can be opened to replace the fuse. (Unlike circuit break-
ers that “trip,” a fuse must be replaced.) When possible, have this
function serviced by an authorized Malibu dealer, who can check the
entire system to determine the source or cause of the fuse malfunc-
tion. If the fuse blows during an outing, never pry or force open the
box. The top should pop off the housing with minimal effort. Inside
the housing will be several fuses, the size is denoted on the top of
the fuse. There is also a primary and secondary fuse box under the
dash that contains fuses. Each box has a labeled/detailed picture of
location, fuse size, and which circuit it protects.
If a fuse blows repeatedly, it is symptomatic of a recurring issue
that must be addressed. Such repair should be undertaken by your
authorized Malibu dealer.
Electrical Harnesses and Wiring
Your Malibu boat is equipped with several electrical harnesses
providing power within the drive train and to various ancillary func-
tions of the boat. Due to the complexity of the boat’s wiring, much of
which is inaccessible inside the hull and under the deck, any time an
issue is suspected involving the wiring or any of the harnesses, the
boat owner is strongly encouraged to have the boat serviced by an
authorized Malibu dealer.
Batteries
Malibu Boats offer batteries as an option. If the boat owner
chooses to equip the boat with batteries of his/her own choosing,
there are certain requirements for starting and the operation of the
boat, which is addressed later in this section. Please review that
information as it can be critical to avoiding a situation in which a
battery(ies) is completely drained and leaves boaters stranded away
from shore, or which can cause significant damage to the recharging
alternator.
Batteries are in the bow in all models and all configurations.
IMPORTANT NOTE FOR ALL BATTERY SYSTEMS:
Note that the bilge
pumps will continue to pull power, even when the isolator switch
is in the OFF position on the boats so equipped.
This is to prevent
swamping of the boat and potential sinking.
Bear in mind that for the
bilge systems to work the battery will necessarily be drained, and
eventually it will cause the battery to run out of charge. Therefore,
under these circumstances, the boat should periodically be started,
and the engine run for a sufficient time to allow the voltmeter read-
ing to return to the desired range of at least 13.6 volts. How often
and how long the engine should be run to recharge the battery will
