can be removed and tested using the
procedure below or by a dealer service
department or a repair workshop. Defective
relays must be replaced as a unit.
Testing
1It’s best to refer to the wiring diagram for
the circuit to determine the proper
connections for the relay you’re testing.
However, if you’re not able to determine the
correct connection from the wiring diagrams,
you may be able to determine the test
connections from the information that follows.
2On most relays, two of the terminals are the
relay’s control circuit (they connect to the
relay coil which, when energised, closes the
large contacts to complete the circuit). The
other terminals are the power circuit (they are
connected together within the relay when the
control-circuit coil is energised).
3Relays are sometimes marked as an aid to
help you determine which terminals are the
control circuit and which are the powercircuit (see illustration). As a general rule,
the two thicker wires connected to the relay
are the power circuit; the thinner wires are
the control circuit.
4Remove the relay from the vehicle and check
for continuity between the relay power circuit
terminals. There should be no continuity.5Connect a fused jumper wire between one
of the two control circuit terminals and the
positive battery terminal. Connect another
jumper wire between the other control circuit
terminal and earth. When the connections are
made, the relay should click. On some relays,
polarity may be critical, so, if the relay doesn’t
click, try swapping the jumper wires on the
control circuit terminals.
6With the jumper wires connected, check for
continuity between the power circuit
terminals. Now, there should be continuity.
8If the relay fails any of the above tests,
renew it.

2Check the fuse if the gauge pointer does
not move from the empty, low or cold
positions. If the fuse is OK, locate the
particular sender unit for the circuit you’re
working on (see Chapter 4 for fuel sender unit
location, Chapter 2 for oil sender unit location,
or Chapter 3 for temperature sender unit
location). Connect the sender unit connector
to earth If the pointer goes to the full, high or
hot position renew the sender unit. If the
pointer stays in same position use a jumper
wire to earth the terminal on the back of the
gauge. If the pointer moves with the back of
the gauge earthed the problem lies in the wire
between the gauge and the sender unit. If the
pointer does not moves with the back of the
gauge earthed check for voltage at the other
terminal of the gauge. If voltage is present
renew the gauge.

6If the voltage is 6 volts, the element is okay
(there is no break). If the voltage is 12 volts,
the element is broken between the centre
of the element and the positive end. If the
voltage is 0 volts the element is broken
between the centre of the element and earth.
7To find the break, place the voltmeter
positive lead against the defogger positive
terminal. Place the voltmeter negative lead
with the foil strip against the heating element
at the positive terminal end and slide it toward
the negative terminal end. The point at which
the voltmeter deflects from zero to several
volts is the point at which the heating element
is broken (see illustration).
Repair
8Repair the break in the element using a
repair kit specifically recommended for this
purpose.
9Prior to repairing a break, turn off the system
and allow it to cool off for a few minutes.
10Lightly buff the element area with fine
steel wool, then clean it thoroughly with
rubbing alcohol.
11Use masking tape to mask off the area
being repaired.
12Thoroughly mix the epoxy, following the
instructions provided with the repair kit.
13Apply the epoxy material to the slit in the
masking tape, overlapping the undamaged
area about 3/4-inch on either end (see
illustration).
14Allow the repair to cure for 24 hours before
removing the tape and using the system.
17 Headlights- renewal
1
Warning: Later models are
equipped with halogen gas-filled
headlight bulbs which are underpressure and may shatter if the surface is
damaged or the bulb is dropped. Wear eye
protection and handle the bulbs carefully,
grasping only the base whenever possible.
Do not touch the surface of the bulb with
your fingers because the oil from your skin
could cause it to overheat and fail
prematurely. If you do touch the bulb
surface, clean it with rubbing alcohol.

3261 Jaguar XJ6 16.5 To determine if a heating element has broken, check the
voltage at the centre of each element. If the voltage is 6-volts, the
element is unbroken; if the voltage is 12-volts, the element is
broken between the centre and the positive end. If there is no
voltage, the element is broken between the centre and earth
16.7 To find the break, place the voltmeter positive lead against
the heated window positive terminal, place the voltmeter negative
lead with the foil strip against the heating element at the positive
terminal end and slide it toward the negative terminal end -
the point at which the voltmeter reading changes abruptly is the
point at which the element is broken

5Pull the headlight out slightly and
disconnect the electrical connector from the
rear of the light, then remove the light from the
vehicle.
6To refit, position the new unit close enough
to connect the electrical connector. Make
sure that the numbers moulded into the lens
are at the top.
7Refit and tighten the retaining ring. Test the
headlight operation.
8The remainder of the refitting is the reverse
of removal.

9Disconnect the electrical connector from
the bulb assembly. Rotate the headlight bulb
connector 1/4-turn anti-clockwise (viewed
from the rear) (see illustration).
10Withdraw the bulb assembly from the
headlight housing.
11Without touching the glass with your bare

18 Headlights- adjustment
5
Note:The following procedure is intended for
emergency use only, and we strongly
recommend that the headlight aim is only
checked using optical beam-setting
equipment. It is important that the headlights
are aimed correctly. If adjusted incorrectly
they could blind the driver of an oncoming
vehicle and cause a serious accident or
seriously reduce your ability to see the road.
The headlights should be checked for proper
aim every 12 months and any time a new
headlight is installed or front end body work is
performed.
1Adjustment should be made with the
vehicle sitting level, the petrol tank half-full
and no unusually heavy load in the vehicle.2Early models with sealed beam headlights
have four adjusting knobs protruding through
the backside of the radiator support. The
vertical (up and down) adjustment knobs are
located above the headlight and the horizontal
(left to right) adjusting knobs are located
below the headlight (see illustration).
3On later models with halogen bulbs,
adjustments are made in the same manner as
described in the previous step, except there
are only two adjusting knobs which tilt the
headlight housing to the desired angle.
4If the headlight housing has been replacedor the vehicle has suffered front-end damage,
refer to following procedure.
5This method requires a blank wall, masking
tape and a level floor.
6Position masking tape vertically on the wall
in reference to the vehicle centreline and the
centrelines of both headlights (see
illustration).
7Position a horizontal tape line in reference
to the centreline of all the headlights. Note:It
may be easier to position the tape on the wall
with the vehicle parked only a few inches
away.

adjustment details

8Adjustment should be made with the
vehicle parked 25 feet from the wall, sitting
level, the petrol tank half-full and no unusually
heavy load in the vehicle.
9Starting with the low beam adjustment,
position the high intensity zone so it is two
inches below the horizontal line and two
inches to the right of the headlight vertical
line. Adjustments are made by turning the
knobs located behind the headlight housings
(see illustration 18.2).
10With the high beams on, the high intensity
zone should be vertically centred with the
exact centre just below the horizontal line.
Note:It may not be possible to position the
headlight aim exactly for both high and low
beams. If a compromise must be made, keep
in mind that the low beams are the most used
and have the greatest effect on safety.
11Have the headlights adjusted by a dealer
service department or service station at the
earliest opportunity.

Check
Note:Check the fuses before beginning
electrical diagnosis.
1Disconnect the electrical connector from
the horn.
2To test the horn, connect battery voltage to
the two terminals with a pair of jumper wires.
If the horn doesn’t sound, renew it.
3If the horn does sound, check for voltage at
the terminal when the horn button is
depressed (see illustration). If there’s voltage
at the terminal, check for a bad earth at the
horn.
4If there’s no voltage at the horn, check the
relay (see Section 6). Note that most horn
relays are either the four-terminal or externally
earthed three-terminal type.
5If the relay is OK, check for voltage to the
relay power and control circuits. If either of the
circuits are not receiving voltage, inspect the
wiring between the relay and the fuse panel.
6If both relay circuits are receiving voltage,
depress the horn button and check the circuit
from the relay to the horn button for continuityto earth. If there’s no continuity, check the
circuit for an open. If the circuit is good, renew
the horn button.
7If there’s continuity to earth through the
horn button, check for an open or short in the
circuit from the relay to the horn.Renewal
