ELECTRICAL PRECAUTIONS
General
The following guidelines are intended to ensure the safety of the operator whilst preventing
damage to the electrical and electronic components fitted to the vehicle. Where necessary,
specific precautions are detailed in the relevant sections of this document, reference to
these precautions should be made prior to commencing repair operations.
Equipment – Prior to commencing any test procedure on the vehicle, ensure that the
relevant test equipment is working correctly and any harnesses or connections are in good
condition. This particularly applies to mains lead or connections.
WARNING: Before commencing work on an ignition system, all high tension
terminals, adaptors and diagnostic equipment for testing should be inspected to
ensure that they are adequately insulated and shielded to prevent accidental personal
contact and to minimise the risk of shock. Wearers of surgically implanted pacemaker
devices should not work in close proximity to ignition circuits or diagnostic
equipment.
Polarity – Never reverse connect the vehicle battery and always observe correct polarity
when connecting test equipment.
High Voltage Circuits – Whenever disconnecting live ht circuits, always use insulated pliers
and never allow the open end of the ht lead to come into contact with other components,
particularly ECU's. Since high voltage spikes can occur on the terminals of the coil while the
engine is running, exercise caution when measuring the voltage at these points.
WARNING: The Xenon headlamp system generates up to 28,000 V and contact with
this voltage could lead to fatality. Make sure that the headlamps are switched off
before working on the system. Refer to the guidelines given in the 'General
Information' section of the Service Repair Procedures Workshop Manual before any
work is carried out.
Connectors and Harnesses – The engine compartment of a vehicle is a particularly hostile
environment for electrical components and connectors. Always ensure these items are dry
and oil free before disconnecting and connecting test equipment. Never force connectors
apart either by using tools or by pulling on the wiring harness. Always ensure locking tabs
are disengaged before removal and note orientation to enable correct reconnection. Ensure
that any protective covers and substances are replaced if disturbed.
