Subsection 04 (INSTRUMENTS AND ACCESSORIES)
Always ensure safety lanyard is not left on its post
after engine is stopped.
IMPORTANT: Leaving the safety lanyard on its
post when engine is not running will slowly dis-
charge the battery.
Antistart Feature
When connecting a safety lanyard cap on the
switch the DESS system inside the MPEM is
activated and will emit audible signals:
– 2 short beeps indicate a right safety lanyard is
being used and gauges are supplied with cur-
rent for 33 seconds. The MPEM will thus allow
the engines to start.
– 1 long beep indicates a wrong safety lanyard
is being used or that the anti-start feature is
defective. Current to gauges is cut after the
audible signal is emitted and the engine cannot
be started.
A wrong safety lanyard is a safety lanyard which is
defective or not programmed in the MPEM mem-
ory.
To better understand the anti-start feature, refer
to DESS (DIGITALLY ENCODED SECURITY SYS-
TEM).
If the MPEM responds differently from what is
mentioned above, refer to the troubleshooting
sectiontofindoutwhy.
Engine Starting
If the MPEM recognizes a valid safety lanyard, it
allows engine to start when the start/stop switch
is pressed.
If start/stop button is held after engine has started,
the MPEM automatically stops the starter when
the engine speed reaches 1000 RPM.
Engine RPM Limiter
The MPEM will limit the maximum engine speed.
Engine Stopping
There are two ways to stop the engine.
Pressstart/stopswitchorremovethesafetylan-
yard cap from the switch.
Power Distribution
The MPEM distributes power from the battery to
most components. Refer to WIRING HARNESS.
Overheat Sensor
When the engine temperature reaches a threshold
value, the MPEM triggers a continuous beep to
indicate overheating.
Diagnostic Mode
In order to facilitate the use of the watercraft, a
system controls the digitally encoded security sys-
tem (DESS) and sends, through a buzzer, some
audible signals informing the operator of a specif-
ic situation. The diagnostic mode is automatically
activated when connecting the safety lanyard cap
to the switch. Refer DIGITALLY ENCODED SE-
CURITY SYSTEM.
Fuses
Components are protected by fuses integrated in
theMPEMandinfuseholderclosetoVCM.Fuses
are identified beside their holder. See below for
fuses location and description.
MPEM
Locate the MPEM in front of engine.
