| 1. | The distributor shaft has a cam that operates the contact breaker.
|
| 2. | This model had triple contact breaker points making timing adjustment complex.
|
| 3. | The ignition firing sequence begins with the points ( or contact breaker ) closed.
|
| 4. | They also make modules for vehicles with two or more sets of contact breakers.
|
| 5. | When the piston was at the right point, the contact breaker opened, breaking the battery current.
|
| 6. | This was a simple iron-core inductor, used with a battery and a switch called a contact breaker.
|
| 7. | The engine operates contact breaker points, which interrupt the current to an induction coil ( known as the ignition coil ).
|
| 8. | Early models used a 6 V electrical system with contact breaker / condenser ignition, whereas later models used a 12 V system.
|
| 9. | When the contact breaker closes, it allows a current from the battery to build up in the primary winding of the ignition coil.
|
| 10. | When the contact breaker opens the circuit, the magnetic field collapses, causing a high electric voltage in the primary and secondary coils.
