Location
The main circuit breaker board is located under the dash panel
closeout, facing aft, except on the XStar, which does not have
this panel, and the ProStar (it is located on the starboard side of
the walk-thru to the bow area). In some models, there is an addi-
tional breaker panel to assist with the accessory load, and where
equipped, it is located near the battery box.
The XStar features digital switching. Instead of a breaker panel.
There are four (4) PDM breakers and a main breaker that are locat-
ed on the battery shut-o switch panel beneath the port aft seating.
If during maintenance or inspection it becomes necessary to
remove or reposition any of the engine’s wiring or wire harness(es),
verify that the wiring has been returned to its original position and
that all harnesses are routed correctly before attempting to use the
boat again. If a wiring clip or retainer breaks, replace it immediately.
Wiring is specifically routed to eliminate problems related to engine
heat, and spray or immersion in liquids. Electrical problems may
result if wiring is moved from its original position.
Operation
On all models except the XStar, if a problem develops with one of
the circuits, switch OFF the circuit and wait for approximately one (1)
minute. Then fully push the appropriate breaker button and switch
ON the circuit. If the circuit continues to trip, there is a problem
somewhere that must be attended to immediately. See your
authorized MasterCraft service department to resolve this matter.
On the XStar, turn OFF the controlling switch; i.e., if the courtesy
lights are not working, turn OFF the Courtesy Light switch. Allow
a few seconds for the digital switching to reset, and then turn the
switch back ON. If the electrical function does not reset, see your
authorized MasterCraft service department to resolve the issue.
