Electrical
Engine Circuit Breaker
Depending on your engine model, the engine may be equipped with a 35 AMP Circuit
Breaker to protect the engine electrical system and components from overload, and is
found on the lower right side of the engine. If your engine should lose power and will not
crank, reset the breaker by firmly pressing the red button (an audible sound will be
heard). For additional engine electrical issues, see your Engine Owners Manual, or
contact your Local Malibu dealership.
Main Circuit Breaker
Located adjacent to the battery is a 80 AMP Circuit
Breaker. If your boats systems lose electrical power,
and you have no dash gauges or your engine does not
turn over, you will need to reset the breaker to restore
power to your boats systems. To reset, find breaker
switch and depress until lever locks into position.
Power loss to the Main Breaker is
an indication of serious issues to
your boats electrical and/or
engine components Contact your
local dealer for evaluation of
these components.
If additional loads are added to the dash feeder circuits, such
as amplifiers, tower lights, etc., this can overload the 80 AMP
breaker. Large loads over 20 AMPS should be wired directly
to the battery with proper overload protection.
Boat Alarms
Malibu boats are equipped with sensors that constantly monitor various functions of the
boat. Certain functions, if outside of pre-determined operating parameters, may activate
an alarm located under the dash. Both the engine Electronic Control Module (ECM) and
the dash gauge computer may activate the alarm.
If the ECM activates the alarm, it will store a trouble code in memory. Stop the boat as
soon as possible and turn off the engine. You will need to have your Malibu dealer run a
diagnostics test to repair the engine and clear any codes from memory. The ECM uses the
engine oil pressure, engine temperature and transmission temperature switches for input
and parameters are stored in the ECM.
If the dash gauge computer activates the alarm, the Multi Function Display Panel will
indicate the source of the problem. If the alarm sounds during operation, stop the boat as
soon as possible and turn off the engine. You will need to have your Malibu dealer run a
diagnostics test to repair the engine and clear any codes from memory. The dash gauge
computer uses a separate set of sending units on the engine, fuel tank and depth
transducer for input and parameters are stored in the computer.
Refer to Section 3, Operation, Starting, for more information on the alarm.
