Introduction. 1  The distributorless ignition system has been around for the last decade. It was designed to replace the mechanical distributor system (HEI) in controlling the ignition secondary coil voltage. This system is comprised of the following components: 1  Crankshaft Timing Sensor: located in the front of the crankshaft to trigger the ignition system. This sensor consists of a single Hall effect magnetic switch activated by 3 vanes on the crankshaft damper and pulley assembly.
The ignition system is divided into two sections, the primary circuit and the secondary circuit. The low voltageprimary circuit operates at battery voltage (12 to 14.5 volts) and is responsible for generating the signal to fire the spark plug at the exact right time and sending that signal to theignition coil.
