Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation: Notes
The Motorcraft Solid State Ignition used on Capri and Fiesta utilizes a Bosch built breakerless distributor and Motorcraft electronic control module and coil. When ignition switch is on, primary circuit is on and 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. Dwell varies with engine speed and cannot be altered, so measurement and adjustment is not required.
