  1. Ignition Systems Or….. How to be a bright spark

  2. Secondary Windings Coil Primary Windings Soft Iron Core Engine Driven Rotor and Magnets Magneto Operation IGNITION SYSTEM IGNITION SYSTEM

  3. S S S S N N N N S S S S N N N N Principal - Coil Windings Volt Meter Each time the magnetic field ‘washes’ through wires An electrical current is produced Called an EMF – Electro Motive Force IGNITION SYSTEM – Faraday Law

  4. Magneto Operation EMF produced in the coil windings The magnetic field passes through soft iron core IGNITION SYSTEM IGNITION SYSTEM

  5. No EMF produced in the coil windings No magnetic field in soft iron core IGNITION SYSTEM

  6. EMF produced in the coil windings again The magnetic field passes through soft iron core again IGNITION SYSTEM

  7. Rotor Arm Condenser Contact Breaker Magneto Unit Spark Generation Power Generation Coil Distribution Magneto Ignition Switch IGNITION SYSTEM – Magneto System

  8. Condenser Secondary Windings Primary Windings Contact Breaker Distributor Coil Ignition Switch Dynamo/ Alternator Battery IGNITION SYSTEM – Dynamo/Alternator System

  9. Adjustable Plate Diaphragm Vacuum Chamber Cap ‘Points’ Cam Inlet Pressure Body Adjuster Input Shaft Centrifugal Weights Typical Distributor Vacuum Advance Centrifugal Advance IGNITION SYSTEM – Distributor

  10. Timing Sensor Timing Disc Coil Packs Engine Speed Sensing Unit Control Unit Ignition Switch Alternator Battery IGNITION SYSTEM – Electronic Systems

  11. Cap Connector Ceramic Body Hexagon Outer Casing Copper Sealing Gasket Securing Thread Gap Outer Electrode IGNITION SYSTEM – Spark Plug

  12. Cap Connector Ceramic Body Seal Hexagon Outer Casing Centre Electrode Copper Sealing Gasket Securing Thread Outer Electrode These surfaces must be kept clean Change Spark Plugs at specified times Make sure the correct Spark Plug is fitted IGNITION SYSTEM – Spark Plug
