ELECTRICAL PRECAUTIONS
Disciplines
Switch off ignition prior to making any connection or
disconnection in the system as electrical surge
caused by disconnecting ’live’ connections can
damage electronic components.
Ensure hands and work surfaces are clean and free
of grease, swarf, etc. as grease collects dirt which
can cause tracking or high-resistance contacts.
When handling printed circuit boards, treat them as
you would a disc - 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 will cause short- circuit and
open-circuit conditions.
Prior to commencing test, and periodically during
test, touch a good earth, i.e. cigar lighter socket, to
discharge body static as some electronic
components are vulnerable to static electricity.
Grease for electrical connectors
All under bonnet and under body connectors are
protected against corrosion by the application of a
special grease on production. Should connectors be
disturbed in service or repaired or replaced, a
grease of this type, available in 150 gm tubes under
Part No. BAU 5811, should again be applied.
NOTE: The use of other greases must be
avoided as they can migrate into relays,
switches etc. contaminating the contacts
and leading to intermittent operation or failure.
