The Electronic ignition system was introduced to cope with stricter emission control laws being enforced by government.

Electronic Ignition systems also assists with lower vehicle maintenance. The system is capable of producing high secondary voltage and has no moving parts therefore has greater accuracy with dwell and timing throughout the life of the components.

Although these systems are very reliable, vibrations, dust, water and engine bay temperatures can cause premature failure of some components withing the system.

Precautions

Most systems have capability to produce a voltage range of 400 volts AC to 70kv AC. So take care when working with these systems.

Here are some precautions when working with these systems.

Switch Ignition off when:

  • Connecting test equipment, timing lights, oscilloscopes etc.
  • Replacing Parts like spark plugs, ignition coil, plug leads etc.
  • Do not disconnect battery while the car is running.

Other things to watch out for are:

  • The coil negative terminal should never be grounded as an anti theft device (kill switch) as it may damage components.
  • Before commencing a compression test make sure you disconnect the ignition coil and electric fuel pump if fitted.
  • Use the correct part numbers when replacing components.
    Do not connect noise suppressor to an ignition coil unless replacing a factory fitted suppressor.
