Breaker points, electronic, and multiple spark discharge systems have similar parts, but they operate differently. Learn how.

The contact-points ignition system has been used on the internal combustion engine since the early 1900s because it is simple and durable. Compared to the computer-controlled ignitions used in ...

That system consisted of breaker points, a condenser, and an ignition coil to store the current. Point timing had to tie in with spark timing via the distributor rotor indexing.

The dash light is necessary with this type of system because without it, once the alternator starts producing current, the 14.2-volt output will follow the R wire back to the ignition switch.

There's no question that the breaker point, or just "points," ignition system was getting long in the tooth by the time the HEI distributor debuted.

However, after learning more about how an ignition system works, as well as the benefits provided by a multi-spark discharge setup, we were sold.
