NOTE :
This sensor turns the low-level oil
light to ON if the connector has been forgot-
ten unconnected even when there is enough oil in
tank.
Speed Sensor
The speedometer gives a reading through a
speed sensor. Speed sensor is installed on ride
shoe. It works with the water flow which turns a
magnetic paddle wheel that triggers an electronic
pick-up that in turn sends a speed signal to the
speedometer.
The paddle wheel is protected by the pick-up
housing.

2. Paddle wheel
STATIC TEST
To verify speed sensor, a resistance test can be
performed with an ohmmeter. Disconnect speed
sensor wires from inside bilge.
Refer to the following chart for speed sensor test-
ing. Always respect polarity in chart.
DYNAMIC TEST
To verify speed sensor, a dynamic test can also be
performed using a battery and a voltmeter.
Disconnect speed sensor wires from inside bilge.
With a 12 VDC battery, connect the positive (+) to
sensor PURPLE / YELLOW wire.
Connect the negative (-) to the sensor BLACK
wire.
Connect the voltmeter positive probe to sensor
BLUE / PURPLE wire and the negative probe to
sensor BLACK wire.
Turn the paddle wheel slowly. There should be a
voltage fluctuation.
VTS Switch
Always confirm first that the fuse is in good con-
dition.
Disconnect BLACK wire, BLUE
/
WHITE wire and
GREEN
/
WHITE wire of VTS switch located in
front of bilge on left side.
Using an ohmmeter, connect test probes to
switch BLACK and BLUE
/
WHITE wires
; then,
connect test probes to switch BLACK and GREEN
/
WHITE wires.
Measure resistance
;
in both test, it should be
high when button is released and must be close
to zero when activated.
