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.

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.

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.

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.
