Speed Sensor
The speedometer gives a reading through a speed
sensor. Speed sensor is installed on riding plate. 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 speedom-
eter.
The paddle wheel is protected by the pick-up
housing.
1. Pick-up housing
2. Paddle wheel
To check if the speed sensor is operational, dis-
connect the speed sensor connector housing
from inside bilge.
Using an appropriate terminal remover (Snap-on
TT600-4), remove the PURPLE/YELLOW and
BLACK/ORANGE wires from the tab housing of
the speed sensor.
Reconnect the PURPLE/YELLOW and BLACK/
ORANGE wires in the receptacle housing.
Connect the positive probe of a multimeter to
speed sensor PURPLE/YELLOW wire and the
negative probe to speed sensor BLACK/ORANGE
wire.
With the safety lanyard removed, depress the start/
stop button to activate the MPEM timer.
Slowly rotate the paddle wheel. Every 1/8 turn, the
observed voltage should fluctuate between 5.5
and 8.5 Vdc.
Speedometer (90 mm)
TYPICAL
The PURPLE wire is the 12 Vdc power source of
the speedometer.
The BLACK wire is the ground.
The PURPLE/YELLOW wire is the pulse signal
from the speed sensor.
