MARELLI Electronic Ignition: Description

NOTE: Some Strada models may be equipped with Bosch electronic ignition systems.

The Marelli electronic ignition system consists of an ignition coil, electronic control module, and a breakerless distributor. See Figure. The control module and ignition coil are mounted on a finned, cast aluminum base which not only cools the units, but also provides a system ground. See Figure. Marelli distributors are equipped with centrifugal and vacuum advance mechanisms. A 4-tooth reluctor is mounted on distributor shaft and combines with the pickup coil assembly to provide control module with electrical signals. Control module analyzes the electrical signals from the distributor pickup coil assembly and provides the coil with proper dwell time and spark timing regardless of engine speed. The control module's current limiter provides a constant current flow to the primary circuit, preventing coil damage.
