How to Master Points Distributor Wiring: A Comprehensive Guide for Enthusiasts

Points Distributor Wiring is an electrical system that distributes current from a single ignition coil to multiple spark plugs in an internal combustion engine. It consists of a set of contact points, a condenser, and a rotating distributor cap with electrical terminals connected to each spark plug.

As the engine runs, the contact points open and close, interrupting the current flow from the ignition coil. This creates a voltage spike that is directed through the condenser and to the distributor cap. The cap then distributes the current to the appropriate spark plug, based on the engine’s firing order. The spark plugs then create sparks that ignite the air-fuel mixture in the engine’s cylinders.

Points Distributor Wiring was once widely used in automotive engines, but has since been largely replaced by electronic ignition systems. However, it remains an important historical development in automotive technology and is still used in some older engines. Its advantages include simplicity, reliability, and low cost.
