Warning: Block the opening
in
the
tank to prevent the escape o f
petrol fumes a n d accidental fuel
spillage.
5 Test the operation of the sender with a
multimeter set to the ohms x 100 scale.
Connect the meter probes to the terminals on
the top of the sender and measure the
resistance with the sender float UP (tank full)
and DOWN (tank empty) (see illustration). If
the readings obtained differ greatly from those
given in the Specifications at the beginning of
this Chapter, the sender is faulty and must be
renewed.
6 Check the operation of the sender; the arm
should move freely without binding. Also
check that the float is held securely on the
arm and that it is not damaged. This will
usually be apparent by the presence of fuel
inside the float. If any of the component parts
are faulty or damaged, fit a new sender.
7 If the sender is good, check the wiring
between the sender and the gauge (see
Wiring Diagrams at the end of this Chapter).
Renewal
8 Remove the sender as described in Step 4.
9 Check the condition of the sender O-ring
and fit a new one if it is deformed or perished.
Insert the sender carefully into the tank, then
turn it clockwise to lock it in position.

Check
1 The oil level waming light in the instrument
cluster should come on temporarily when the
ignition is first turned on as a check of the
waming circuit. If the light fails to come on, first
check the bulb (see Section 18), then check the
wiring between the instrument cluster wiring
connector and the starter relay (see Wiring
Diagrams at the end of this Chapter).
2 If the waming light in the instrument cluster
fails to come on when the oil is low, first check
the bulb (see Section 18). If the bulb is good.
remove the storage compartment to access
the oil level sensor in the top of the oil tank
(see Chapter 7).

3 Disconnect the wiring connector from the
top of the sensor (see illustration). With the
ignition switched on, check for voltage at the
black wire terminal in the connector. If there is
no voltage, check the wiring between the
connector and the ignition switch (see Wiring
Diagrams at the end of this Chapter).
4 To test the sensor, remove it from the oil
tank as described below.
5 Using a multimeter set to the ohms x 1
scale, connect the meter probes to the
terminals on the top of the sensor and
measure the resistance with the sensor float
UP (tank full) and DOWN (tank empty) (see
illustration). If the readings obtained differ
from those given in the Specifications at the
beginning of this Chapter, the sensor is faulty
and must be renewed.
6 If the sensor is good, check the wiring
between the sensor and the instrument cluster
(see Wiring Diagrams at the end of this Chapter).

Warning: To prevent the risk o f
short circuits, disconnect the
battery negative (-ve) lead before
making any ignition (main) switch checks.
Check
1 Remove any body panels as required for
access (see Chapter 7). Disconnect the
battery negative (-ve ) lead, then pull back the
boot on the wiring connector and disconnect
the connector
(see
illustrations).
2 Using an multimeter or a continuity tester,
check the continuity of the connector terminal
pairs (see the Wiring Diagrams at the end of
this Chapter). Continuity should exist between
the connected terminals when the switch is in
the indicated position.
3 If the switch fails any of the tests it must be
renewed. Note: For machines fitted with an
ignition immobiliser, from July 2002
