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 brake disc -
hold by the edges only; note that some electronic components...
