MAINTENANCE VEHICLE EXTERIOR
CHECK/ADJUST HEADLAMP ALIGNMENT
Check/adjust headlamp and auxiliary alignment.
CHECK FRONT WHEEL ALIGNMENT
Use recognised wheel alignment equipment to
perform this check and adjustment.
See STEERING,
Adjustment, Front Wheel Alignment
REMOVE WHEELS, CHECK TYRES
Check tyres (including spare) for compliance with
manufacturers' specification.
Check visually for cuts, lumps, bulges, uneven tread
wear and tread depth. Check road wheels for
damage.
Check/adjust tyre pressures.
CHECK/TIGHTEN TOWING BRACKET FITTINGSINSPECT BRAKE PADS FOR WEAR, CALIPERS
FOR LEAKS AND CONDITION
Check thickness of brake pads, fit new pads if
minimum thickness is less than 3,0mm. Check brake
pads for oil contamination. If new brake pads required.
See BRAKES, Repair, Front Brake Pads
or.See BRAKES, Repair, Rear Brake Pads
WARNING: When renewing brake pads, it
is essential that only genuine components
with correct grade of lining are used.
Always fit new pads as complete axle sets, NEVER
individually or as a single wheel set. Serious
consequences could result from out of balance
braking due to mixing of linings.
Refit road wheels
Fit road wheels in original hub position. Secure in
position with wheel nuts, do not fully tighten wheel
nuts at this stage, lower vehicle and finally tighten
wheel nuts to correct torque.
Alloy wheels:
130 Nm.
Steel wheels:130 Nm.

DESCRIPTION AND OPERATION Wash wipe function
With the ignition switched on, power is supplied via a
fuse to the multi-switch, a control unit and a park
switch which is driven by the wiper motor.
Single wipe A
Pull the lever down and release immediately.
NOTE: With the lever held down, the
wipers will continue operating at high
speed until it is released.
Intermittent wipe B
Turn switch to second position.
Normal speed wipe C
Turn switch to second position.
Fast speed wide D
Turn switch to third position.
Variable delay (intermittent wipe)
Rotate the switch to vary the delay between wipes.
Windscreen washer E
Pull the lever towards the steering wheel. The
windscreen washers will operate in conjunction with
the wipers for as long as the lever is held in this
position.
Headlamp washers
The headlamp washers operate automatically
whenever the windscreen washers are operated,
provided the headlamps are illuminated and switched
to dipped beam. For continuous washing, hold the
windscreen washer control in the washposition E.
REAR WINDOW WIPER AND WASHER
OPERATION
The illustration J5375 also locates and identifies the
main components of the rear window wiper and
washer system which is operated by two switches
mounted on the right hand side of the instrument
binnacle.
Rear window wipe A
Press the switch to operate: after continuously wiping
3 or 4 times, the wiper operates intermittently (approx
once every 6 seconds) until switched off.
Rear window washer B

FAULT DIAGNOSIS GENERAL INFORMATION
The electrical fault diagnostic tool on Discovery
vehicles is Testbook. Detailed information of electrical
systems, component locations and circuit diagrams
are covered in the Discovery Electrical
Troubleshooting Manual.
See INTRODUCTION,
Information, Fault Diagnostic Equipment
This section covers checks of the charging and
ignition system.
GENERATOR TESTING
Service repair no - 86.10.01
Charging system check
1.Check battery is in good condition, with an open
circuit voltage of at least 12.6 V. Recharge or
substitute battery to carry out test.
2.Check drive belt condition.
See SECTION 10,
Maintenance, Under Bonnet [Hood]
Maintenance
3.Check battery connections are clean and tight.
4.Check generator connections are clean and
tight.
5.Ensure there is no drain on battery from, for
example, interior, under bonnet [hood] or door
edge lamps.
Generator test
Following instructions refer to use of suitable test
equipment using a carbon pile rheostat.
6.Connect test equipment referring to
manufacturer's instructions.
7.Start engine and run at 3000 rev/min without
accessory load.
8.Rotate carbon pile load control to achieve
greatest output (amps) without allowing voltage
to fall below 12.0 V. A reading in amps, of
generator output, minus 10% to allow for EFI
and Ignition loss, should be obtained.
9.Run engine at 3000 rev/min, switch selector to
regulator test, read voltmeter. A reading of 13.6
to 14.4 V should be obtained.
10.Switch selector to diode/stator test, switch on
headlamps to load generator. Raise engine
speed to 3000 rev/min, read voltmeter, needle
must be within 'OK' range.TESTING IN POSITION
Charging circuit resistance test.
1.Connect a low range voltmeter between
generator terminal marked B+ and positive
terminal of battery.2.Switch on headlamps, start engine. Run engine
at approximately 3000 rev/min. Note voltmeter
reading.
3.Transfer voltmeter connections to frame of
generator and negative terminal of battery, and
again note voltmeter reading.
4.If reading exceeds 0.5 volt on positive side or
0.25 volt on negative side, there is a high
resistance in charging circuit which must be
traced and remedied.
