Crusader Sync/Cruise Panel Functions - Crusader 5.0L MPI Instruction Manual

With both engines running, in neutral, and with both
throttle handles pulled back to the Idle/Start position:
3. Press the Syn/Cru Mode switch to the ON
position. The Sync Lamp should be blinking, or
steady ON, at this point.
4. With the Sync Lamp blinking or steady ON, start
with the Port engine, and SLOWLY push each
throttle forward, one at a time, and note which
throttle increases engine RPM's.
5.. Place the throttle that DOES NOT INCREASE
RPM'S in the wide-open-throttle position.
6. Move the throttle handle that does increase
RPM's forward slowly and observe that both
engines increase in RPM's. This engine is the
Master engine.
Return the throttle handles to their Idle/Start
positions, then place the Syn/Cru Mode Switch to
the OFF position.
CRUSADER SYNCHRONIZATION / CRUISE
PANEL FUNCTIONS
Refer to Figure 5-6.
(A) Syn/Cru Mode Switch - Switch A is a two position
switch, which turns the engine synchronization and
cruise functions ON or OFF. The cruise functions
will not operate until the Syn/Cru Mode Switch (A)
is pushed to the ON position even for single engine
applications.
NOTE: Sync and Cruise functions that have been
enabled, when Switch A is pushed to the OFF position,
will remain in control of the engines until both throttle
handles are pulled back below the previous set point.
(B) Speed Set/Cancel Switch - Switch B is a
Momentary ON - OFF - Momentary ON, three
position switch, which controls the Cruise function.
When you have reached the desired cruise speed,
press Switch B to the Set position and move the
Master throttle handle to the wide open throttle
position. The engine ECM stores the Set value
in memory and controls both engines to the Set
RPM. Pressing Switch B to the Cancel position
and moving the Master throttle handle below the
Set point will disengage Cruise mode, engine
Synchronization is not affected.
NOTE: If a cruise speed has been set and Switch A is
pushed to the OFF position, or Cruise Mode is Cancelled
by Switch B, the Set speed will remain in the ECM
memory. The stored Set speed may be resumed when
the engines are brought back into Sync/Cruise Mode,
even if the engines' ignitions have been turned off.

(C) Speed (+)/Res / (-) Switch - Switch C is the same
type of switch as switch (B), it is used to modify or
resume the Cruise mode Set speed. If Cruise Mode
has been Cancelled and the previous Set speed
is still desired, momentarily pressing Switch C to
the (+)/Res position then move the Master throttle
handle past the previous set point this will Resume
Cruise Mode at the previous Set speed. While in
Cruise Mode, momentarily pressing Switch C to the
(+)/Res position will increase the engine Set speed
20 RPM each time it is pressed. Pressing Switch
C to the (-) position will decrease the engine Set
speed 20 RPM each time it is depressed. Pressing
and holding Switch C, a minimum of 3 seconds, will
slowly ramp engine speed up or down.
(D) Sync Lamp - Indicates the status of the Sync/
Cruise system. OFF - indicates the Sync/Cruise
system is off; Switch A is in the OFF position. ON
- indicates the Sync/Cruise system is enabled and
in Synchronization Mode; Switch A is in the ON
position and the Master throttle has control over
both engines. Flashing - indicates that the Sync/
Cruise system is enabled but is unable to achieve
synchronization because the Slave throttle is below
the Master throttle position.
(E) Cruise Lamp - Indicate the status of Cruise Mode.
OFF - indicates that a cruise speed has not been set
or Cruise Mode has been Cancelled. ON - indicates
that Cruise Mode has been engaged and the
desired cruise speed has been achieved. Flashing
- indicates that Cruise Mode is engaged but the
cruise Set speed has not been met. The previous
set speed may be Resumed and/or the Master
throttle position is below the previous Set speed.
