GENERAL INFORMATION
Connectors and harnesses
Electrical Precautions
The engine compartment of a vehicle is a particularly
hostile environment for electrical components and
connectors:
l
Always ensure electrically related items are dry
and oil free before disconnecting and
connecting test equipment.
Ensure disconnected multiplugs and sensors
are protected from being contaminated with oil,
coolant or other solutions. Contamination could
impair performance or result in catastrophic
failure.
General
The following guidelines are intended to ensure the
safety of the operator while preventing damage to the
electrical and electronic components fitted to the
vehicle. Where necessary, specific precautions are
detailed in the individual procedures of this manual.
l
Equipment
Never force connectors apart using tools to
prise apart or by pulling on the wiring harness.
Always ensure locking tabs are disengaged
before disconnection, and match orientation to
enable correct reconnection.
Prior to commencing any test procedure on the
vehicle ensure that the relevant test equipment is
working correctly and any harness or connectors are
in good condition. It is particularly important to check
the condition of the lead and plugs of mains operated
equipment.
l
l
l
Ensure that any protection (covers, insulation
etc.) is replaced if disturbed.
Polarity
Having confirmed a component to be faulty:
Never reverse connect the vehicle battery and
always ensure the correct polarity when connecting
test equipment.
l
l
l
Switch off the ignition and disconnect the
battery.
Remove the component and support the
disconnected harness.
When replacing the component keep oily hands
away from electrical connection areas and push
connectors home until any locking tabs fully
engage.
High voltage circuits
Whenever disconnecting live ht circuits always use
insulated pliers and never allow the open end of the
ht lead to contact other components, particularly
ECU's. Exercise caution when measuring the voltage
on the coil terminals while the engine is running, high
voltage spikes can occur on these terminals.
Battery disconnection
Before disconnecting the battery, disable the alarm
system and switch off all electrical equipment. If the
radio is to be serviced, ensure the security code has
been deactivated.
CAUTION: To prevent damage to electrical
components, always disconnect the battery
when working on the vehicle's electrical system.
The ground lead must be disconnected first and
reconnected last.
CAUTION: Always ensure that battery leads are
routed correctly and are not close to any
potential chafing points.
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.
