ELECTRICAL SYSTEM

CAUTION: To prevent severe electrical shock extreme care must be taken when
working on or near the electronic ignition system as dangerous high tension voltages
are produced in both the primary and secondary circuits. See the text for
precautionary notes.

1. BATTERY AND CHARGING SYSTEM

TROUBLE SHOOTING

BATTERY UNDERCHARGED

3.

Loose or broken drive belt: Adjust or renew

the drive belt.

4.

Faulty alternator regulator; Renew the regu-

lator unit.

5.

Faulty battery: Install a new battery of

the
recommended type and capacity.

6.

Faulty alternator: Overhaul or renew the

alternator.

7.

Fault in the charging circuit wiring: Check

and repair or renew the wiring harness.

8.

Faulty connections in the charging circuit:

Check and repair the connections.

9.

Fusible link blown; Rectify the fault and

renew as necessary.

NOTE: Check the state of charge (specific
gravity) of the battery- as described under
the
Battery heading in this section. If the battery
is undercharged, check the possible causes in
the order given.

BATTERY OVERCHARGED

•

Faulty alternator regulator unit:

Renew the
regulator unit.

•

Faulty alternator: Overhaul or

renew the
alternator.

•

Faulty charging circuit wiring or

connec-
tions: Check and renew or repair the faulty
compo-
nents.

NOTE: An overcharged battery is indicated
by continual loss of water through boiling.

Electrical System

191

This is usually accompanied by discoloura-
tion of the electrolyte.

CHARGE INDICATOR LAMP REMAINS ON

• Loose or broken alternator drive belt: Adjust

or renew the drive belt.

• Faulty regulator unit: Check and renew the

regulator unit.

• Faulty alternator: Check and overhaul the

alternator.

• Short to earth in the warning lamp circuit:

Check and repair the circuit.

Checking the alternator drive belt for deterioration.

CHARGE INDICATOR LAMP DOES NOT
OPERATE

•

Lamp bulb blown: Check and renew the

faulty bulb.

•

Open circuit in the wiring or bulb socket:

Check and rectify the open circuit.

•

Faulty alternator diode: Overhaul the alter-

nator.

NOISE IN DRIVE BELT OR ALTERNATOR

( 1 ) Drive belt frayed or out of alignment with

the pulleys: Renew the drive bell or align the pulleys.

•

Loose alternator mounting bolts or worn

bearings: Tighten the mounting bolts or renew the
bearings.

•

Loose alternator pulley: Tighten the pulley

retaining nut.

•

Faulty alternator: Overhaul or renew the

alternator.

•

Faulty diodes in the alternator: Overhaul the

alternator, install a new heat sink.

NOTE: To check if the noise is in the
alternator or drive belt, loosen the alternator
and remove the drive belt. If the noise is
gone when the engine is run for a short time
check the serviceability of the belt and
alternator components.

2. BATTERY AND STARTING SYSTEM

TROUBLE SHOOTING

STARTER LACKS POWER TO CRANK ENGINE

( 1 ) Battery undercharged: Check the charging

system and rectify as necessary.

Cleaning the battery terminals using a battery post

cleaner.

•

Battery faulty, will not hold charge: Check

and renew the battery.

•

Battery leads or terminals loose or corroded:

Clean and tighten the leads or terminals.

•

Faulty starter motor: Check and overhaul the

starter motor.

•

Faulty starter solenoid switch or contacts:

Check and renew the solenoid as necessary.

STARTER WILL NOT ATTEMPT TO CRANK
ENGINE

(1) Open circuit in the starting system : Check

for dirty or loose leads or terminals, dirty commuta-
tor, faulty solenoid or faulty switch. On automatic

Spin the alternator pulley over by hand to check the

bearings for noise.

192

Electrical System

transaxle models, check for a faulty or incorrectly
adjusted neutral safety switch.

1.

Discharged battery: Check for a fault or short

circuit in the system.

2.

Battery fully charged but will not crank

engine. Check for a locked drive and ring gear,
internal starter fault or seized engine.

3.

Fusible link blown: Check and repair the

cause and renew as necessary.

NOTE: Rotate the engine by hand to ensure
that the starter drive is not locked with the
flywheel ring gear and that the engine is not
seized. Ensure that the ignition key is
turned off before rotating the engine.

3. LIGHTING SYSTEM TROUBLE SHOOTING

LAMP OR LAMPS FAIL TO LIGHT

1. Faulty bulb(s): Check and renew the faulty

bulb(s).

2. Open circuit in the wiring or connections:

Check the lamp circuits and rectify as necessary.

1.

Faulty lamp switch: Check and if necessary

renew the lamp switch.

2.

Faulty fuse or fuse connection: Repair the

fuse connection or renew the fuse.

3.

Lamp relay faulty: Check and renew as

necessary.

NOTE: Switch on the lamps concerned and
using a test lamp, check that the lamp
circuits are operating. This is best done by
starting at the lamp wiring connector or
bulb holder and working back to the power
source.

LAMP OR LAMPS INCORRECTLY
ILLUMINATED

1.

Lamp or lamps incorrectly earthed: Check

the lamp earth for looseness or clean the contact,
either at the lamp body or wire.

2.

Incorrect bulbs installed: Check the bulb

wattage and voltage and renew with the correct type if
necessary.

3.

Dirty or damaged lamp reflector: Clean or

renew the lamp reflector.

4.

Faulty bulb: Check with a known serviceable

bulb and renew if necessary.

5.

Dirty lamp lens: Clean or renew the lamp

lens.

6.

High resistance or faulty connections be-

tween the alternator and battery: Check the circuit
and rectify the condition.

7.

Poor earth connection between the battery

and the engine or alternator: Check the battery earth
lead and the strap between the engine and the body.

8.

Voltage regulator faulty: Check and renew

the voltage regulator.

NOTE: The most common cause for this
condition is dirty terminals on the earth
leads. Check all earth leads at their earthing
points.

4. TURN SIGNAL LAMP TROUBLE SHOOTING
