About Distributors

What is a distributor, how does it work, and why is it important?

A distributor is an enclosed rotating shaft used in spark-ignition internal combustion engines that have mechanically-timed ignition.

The distributor’s main function is to route secondary, or high voltage, current from the ignition coil to the spark plugs in the correct firing order, and for the correct amount of time. Except in magneto systems, the distributor also houses a mechanical or inductive breaker switch to open and close the ignition coil’s primary circuit.

The central component of the distributor is the shaft, which is what makes the rotor rotate and ‘contact’ the distributor cap ends to make the spark. This drive shaft is connected to a drive gear, and you can see different types of drive gear here.

In order for your car to start properly and run effectively, your distributor, rotor arm, ignition kit (or points and condenser), ignition coil and HT leads all need to be working perfectly.
