Location
The location of the main circuit breaker board varies depending
on the model in question. On NXT and XT models, the main breaker
board is located under the dash panel closeout, facing aft. On X
and X Star models, the main breaker board is found behind a door
in the bow walkthrough. On the ProStar, the main breaker board is
found beneath the jump seat.
On all models, there are some breakers (PDM breakers) which are
reset using a digital switching system. The operator may reset
them from the “PDM Diagnostics” menu on the dash screen, where
the status of each PDM circuit is displayed. PDM-powered circuits
may also be reset by restarting the battery switch cycle or by
pressing the main PDM switches on the main breaker board.
For safety purposes, it is important to make sure that all
electrical wiring retains its proper position and routing. If during
maintenance or inspection it becomes necessary to remove or
reposition any of the engine’s wiring or wire harnesses, verify that
the wiring has been returned to its original position and that all
harnesses are routed correctly before you attempt to use the boat
again. If a wiring clip or retainer breaks, replace it immediately.
Operation
Two types of circuit breaker—thermal and PDM—are found on
MasterCraft boats. Operation method varies depending on the
type of breaker that has tripped. Circuits controlled from the
dash screen use PDM breakers, and should be reset from the
“Diagnostics” screen menu. All other components (except auto
bilge) use thermal breakers, and should be reset from the main
board.
If a problem develops with one of the non-PDM circuits (i.e. any
circuit not controlled from the dashboard touchscreen), access
the main breaker board and shut o the circuit. Wait one (1)
minute. Push the appropriate breaker button and switch the circuit
on. If the circuit continues to trip, there is a problem requiring
urgent attention from an authorized MasterCraft dealer.
To reset PDM circuits, access the “Diagnostics” menu on the dash
screen. Find the toggle for the circuit and reset it. (If the circuit has
tripped, the menu will display an orange, red, or yellow icon beside
the problematic circuit, depending on the issue encountered.)
Allow a few seconds to pass while the digital switching resets.
Turn the circuit back on. If the circuit continues to trip, there is a
problem requiring urgent attention from an authorized dealer.
Note: There are several red PDM switches on the main breaker
board. These are the main PDM switches; they control all systems
on a given PDM. Use these switches to reset an entire PDM if that
PDM displays a fault reading on the screen.
