Electrical Precautions (page 2 of 2)

GENERAL INFORMATION

03-20

After re-connecting the battery, the steering wheel 
must be turned to full LH and RH lock (with engine 
running). This allows the DSC system to relearn the 
steering wheel position. Failure to do so will result in 
a variety of instrument warning lights being 
illuminated. 

Battery charging
Only recharge the battery with it removed from the 
vehicle. Always ensure any battery charging area is 
well ventilated and that every precaution is taken to 
avoid naked flames and sparks.

Ignition system safety precautions
The vehicle's ignition system produces high voltage 
and the following precautions should be observed 
before carrying out any work on the system.

WARNING: Before commencing work on an 
ignition system, ensure all high tension 
terminals, adapters and diagnostic equipment 
are adequately insulated and shielded to prevent 
accidental personal contacts and minimise the 
risk of shock. Wearers of surgically implanted 
pacemaker devices should not be in close 
proximity of ignition circuits or diagnostic 
equipment.

Disciplines
Switch off the ignition prior to making any connection 
or disconnection in the system to prevent electrical 
surges caused by disconnecting 'live' connections 
damaging electronic components.

Ensure hands and work surfaces are clean and free 
of grease, swarf, etc. Grease collects dirt which can 
cause electrical tracking (short-circuits) or high-
resistance contacts.

When handling printed circuit boards, treat with care 
and hold by the edges only; note that some electronic 
components are susceptible to body static.

Connectors should never be subjected to forced 
removal or refit, especially inter-board connectors. 
Damaged contacts can cause short-circuit and open-
circuit fault conditions.

Prior to commencing test, and periodically during a 
test, touch a good vehicle body earth to discharge 
static charge. Some electronic components are 
vulnerable to the static electricity that may be 
generated by the operator.

Grease for electrical connectors
Some under bonnet and under body connectors may 
be protected against corrosion by the application of a 
special grease during vehicle production. Should 
connectors be disturbed in service, repaired or 
replaced, additional grease should be applied: Part 
No. BAU 5811, available in 150 gm tubs. 

NOTE: The use of greases other than BAU 5811 
must be avoided as they can migrate into relays, 
switches etc. contaminating the contacts and leading 
to intermittent operation or failure.
