Description & Operation: Notes
Solid State Ignition system uses an electronic module to control system, a breakerless distributor and an oil filled coil. When ignition switch is on, primary circuit is on and ignition coil is energized. As distributor shaft rotates, the distributor generates signals causing module to break the primary current and induce secondary voltage in coil. A timing circuit in module turns primary circuit on again to energize coil for next spark cycle. The dwell varies with engine speed and cannot be altered, so any measurement is unnecessary.
