The contact breaker points ignition system An essential part in any elderly motorcycle is the ignition system operated via a contact breaker or breaker points ignition system.

Electronic ignition system using contact breaker. ELECTRONIC IGNITION SYSTEM The basic difference between the contact point and the electronic ignition system is in the primary circuit. We know conventional ignition systems use breaker points to trigger induction on the coil. In older carbureted cars the contact breaker CB point ignition system is used to fire the spark plugs.

The ignition coil consists of two transformer windings the primary and secondary. 1 and its electrical connections in Fig. The secondary circuits are practically similar to previous systems.

To burn the lean mixture in the combustion chamber electronic ignition system produces a stronger spark that is really great as compared to the Battery and Magneto ignition system. A contact breaker is an electrical device generally used in the ignition system of an internal combustion engine. In the contact breaker system the primary circuit is opened and closed by the electronic control unit shown in Figure 235.

Later motorcycles dispensed with the contact breaker in lieu of electronics which we will cover in a later article. Watch the animated video showing the working of electronic ignition system. In some time the opening angle of the breaker point will shift because this is one of the moving parts and there is definitely a wear usage.

Contact breaker points type ignition systems as fitted to most Ford models up to around 1980 although it lasted up to 1987 for the Capri can have either a ballast fitted in the wiring loom or not. The power source is a lead-acid battery kept charged by the cars electrical system which generates electricity using a dynamo or alternator. It is different from the other ignition system in the contact breaker section.

You can convert the ignition system of your car from CB-point-cum-condenser type into electronic using transistorised switching. That means the electronic ignition system does not require adjusment as in conventional ignition. The system is powered by a lead-acid battery which is charged by the cars electrical system using a dynamo or alternator.

The primary circuit in a contact point ignition system is open and closed by contact points. Quite simply it is a resistor that has the purpose of reducing the voltage to the coil. Instead of the contact breaker An armature is placed.

This armature is a pulse or signal generator that triggers the ignition module also called the Electronic Ignition Control Unit or Electronic Ignition Module. The basic difference between contact point and electronic ignition systems is in the primary circuit. Contact breakers are sometimes referred to as points and are typically used to temporarily interrupt the electrical current passing through an ignition coil.

For many years the contact point ignition was the favored system to control the timing of the ignition spark. The contact point ignition system consists of. In the electronic system the primary circuit is open and closed by the electronic control unit ECU.

However as electronics in general became more reliable and less costly to produce manufacturers turned to fully electronic systemscutting out the mechanical contact points. This system still has a distributor but the breaker points have been replaced with a pickup coil and theres an electronic ignition control module. Electronic Ignition System The need for higher mileage reduced emissions and greater reliability has led to the development of the electronic ignition system.

The engine operates contact breaker points which interrupt the current flow to an induction coil known as the ignition coil. Know the basic working of an automobile ignition system working on battery. Although the conventional mechanical contact breaker point type electrical ignition system has been very common in use because of its simplicity yet due to its drawbacks and limitations the same is being fast replaced by the electronic ignition system.

The engine operates contact breaker points which interrupt the current to an induction coil known as the ignition coil. In this system the contact breaker points assembly in the Battery ignition system is replaced by the armature.
