batteries to be isolated from all circuits. The COMBINE setting
should be reserved only for emergency starting when one battery
has failed while on an outing.
NOTE: The switch knob may be removed when it is in the OFF posi-
tion. This is a security feature to ensure that batteries are OFF. If
the engine will not start because the battery is discharged, follow
recharging instructions described in the Electrical Instructions
section of the Owners Manual.
Troubleshooting
Because battery needs can vary substantially depending on a num-
ber of factors in usage from boating locations to number of electri-
cal components on the boat, MasterCraft does not place a specific
battery or batteries in the boat. The company strongly encourages
you to discuss this critical matter with your authorized MasterCraft
dealer prior to purchase and placement of the battery in the boat. All
batteries must have 750 CCA (cold cranking amps). Less can result
in too-fast discharge of the battery charge and may leave boaters
stranded on the water. Spiral cell batteries are recommended.
Review all electrical information provided in this Owner’s Manual
prior to first time operation of the boat.
LOW VOLTAGE BATTERY ALARM
Models
All
Purpose
In the event that the stereo has been functioning when the boat is
not ON and running, the voltage drain on the battery (or batteries)
may result in diculties with restarting the boat. It may also cause
intermittent erroneous or fluctuating gauge readings. When the
voltage level reaches 11.5 volts or below, the system will shut o the
stereo and sound the alarm.
Location
Internal and unseen
Operation
Generally, the appropriate action is to leave the stereo OFF, as well
as disengaging any other peripheral electrical components, and
keying ON the engine. Running the engine at a moderate rate for
several minutes without the additional drain of stereo and unnec-
essary electrical equipment will allow the alternator to recharge the
battery or batteries, unless the battery(ies) have been used to the
extent of their life span.
