What does a Duraspark ignition do?

The Duraspark II ignition coil is capable of generating a higher voltage than the regular coil. The wiring is attached via a special snap-on connector. Power is supplied to the coil in the same fashion as the older breaker point ignition. This ignition system is a popular swap into earlier cars and trucks.

What is a Duraspark system?

From Wikipedia, the free encyclopedia. The Duraspark II is a Ford electronic ignition system. Ford Motor Company began using electronic ignitions in 1973 with the Duraspark electronic ignition system and introduced the Duraspark II system in 1976.

When did AMC go to electronic ignition?

1975
Chrysler made electronic ignition standard in 1973; GM, Ford and AMC followed in 1975.

How does the Duraspark 2 Ignition module work?

Duraspark II uses a variable reluctance magnetic pickup in place of traditional breaker points. The signal from this pickup is amplified by the control module to drive the ignition coil. The module hold a fixed dwell time, and features automatic retard while cranking to reduce the load on the starter motor.

How to troubleshoot a 1977 Ford Duraspark ll ignition?

Inspect the circuit from the starter solenoid “S” terminal, if the voltage is weak or missing entirely. Replace the solenoid if no faults are found in the circuit. Probe the red wire leading to the ignition module with the ignition switch in the “Run” position to ensure a proper voltage signal.

Do you need WH wire for Duraspark II?

A DURASPARK II setup requires full BAT VLT to the module (keyed through IGN SW) and if using a DURASPARK II coil, it (coil) must be run through a resistor. The WH wire is an ignition timing retard to make staring the engine a little easier on the starter motor.

What’s the difference between Duraspark I and II?

Even though both I and II use a control box, it’s important to note that DURASPARK is classified as an Inductive Discharge Ignition (IDI), not a Capacitive Discharge Ignition (CDI). For the rest of this article we’ll refer to DURASPARK II simply as DURASPARK.

Why are there no points in a Duraspark ignition?

With a duraspark system there are no points, as it is the function of the ignition module to disrupt the current through the coil. The advantage of electronic ignition over points is simply the speed and reliability of an electronic switch is far superior to that of a mechanical switch.

What are the changes to a Duraspark distributor?

The biggest change, apart from the control box redesign, was the large distributor cap to handle the increased spark energy. The system consists of a magnetic reluctor and pickup in the distributor, and an ignition module to trigger the coil. Typically, the distributors have both mechanical and vacuum advance mechanisms.
