Section 05 ELECTRICAL SYSTEM
Subsection 05 (ACCESSORIES AND LIGHTING SYSTEM)
The Speedometer Is Lighted But the
Needle Does Not Move
Check the speed sensor and the wiring harness.
If the speed sensor and the wiring harness are
good, change the speedometer.
Installation
The installation is the reverse of the removal pro-
cedure.
SPEED SENSOR
Test
Install the supply harness (P/N 529 035 869) with
the supply cable (P/N 529 035 997).
NOTE: Remove the headlight system fuse to save
the battery during the test.
Static Test
Unplug the speed sensor connector.
A33E1MA
Using the multimeter FLUKE 111 (P/N 529 035
868), measure the voltage between BLACK/BLUE
and RED/GREY wires. The obtained value should
be the battery voltage.
Measure the voltage between BLACK/BLUE and
GREEN/WHITE wires. The obtained value should
be ±1 volt under battery voltage.
Dynamic Test
Install 3 pins in each speed sensor connector.
Install wire jumpers between pins.
A33E1NA
Lift the rear of the vehicle.
Connect multimeter probe on GREEN/WHITE and
BLACK/BLUE wires.
Turn the track slowly. The voltage should be
12 volts then drop to O.L.
If the obtained value is out of specifications,
change it.
TACHOMETER
Test
No Light But the Needle Moves
The tachometer is supplied through the
speedometer. Check the voltage between pins 9
and 10 of tachometer connector.
The obtained value should be the battery voltage.
If not, check connections and wiring harness.
If the voltage is good, replace the tachometer.
The Needle Does Not Move
No lights, see speedometer
With lights, check RPM signal on pin 7 of
speedometer connector.
