Troubleshooting
Whenever a breaker trips repeatedly, this indicates a situation
requiring prompt attention. You should take the boat to an
authorized MasterCraft dealer for service. If you attempt self-
repair, MasterCraft is not liable for any resultant damages.
SINGLE BATTERY
Location
The location of the battery switch varies depending on the model
in question. On the NXT, the switch is found under the dash. On the
ProStar, it is found under the center jump seat.
Operation
For normal operation, the battery switch should be placed in the
“On” position. This allows the engine and all accessories to receive
power, letting the engine run through the alternator to recharge
the battery. When transporting the boat by trailer or placing it in
storage, one should place the switch in the “O” position. This will
allow the battery to remain isolated from all circuits.
Models
ProStar and NXT models rely
on a single battery.
Purpose
When properly operated,
the battery allows the
boat’s engine to crank over
with immediacy, eciently
supporting the various
electrical loads onboard.
