How do you test a Duraspark module?

How do you test a Duraspark module?

Measure the cranking voltage to the ignition module, or “brain-box”. Probe the white wire leading into the module while cranking the engine. 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.

How do you diagnose a bad pickup coil?

Signs of a Bad Pickup Coil

1. No Engine Spark. The pickup coil sends the signal from the ignition module to the spark plugs during the ignition process.
2. Rough Idle. Because the spark plugs are not communicating proper timing to the fuel injectors, a rough idle may occur.
3. Engine Stall/Failure to Accelerate.

What are the signs of a bad ignition module?

Signs of a Bad Ignition Module

• Acceleration Issues. The vehicle may shake, vibrate or jerk when the gas pedal is pressed. There may be hesitation or lack of power during increases in speed.
• Temperature Problems. A faulty ignition module can cause a vehicle to overheat.
• No Power. The engine may turn over without starting.

How do you test an electronic ignition module?

Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.

What does a ballast resistor do?

In simple terms, the ballast resistor in a Mopar limits the amperage, or current flow, through the coil while the engine is running, thereby extending the life of the coil and breaker points of the distributor.

What years did Ford use Duraspark?

Duraspark II electronic ignition was used on 1977 to 1984 Ford V-8 passenger car and light truck engines. This article refers to the Duraspark II control module with a BLUE strain relief bushing, one 4-pin connector, and one 2-pin connector.

How do you test a pickup coil with a multimeter?

Connect the red (positive) lead of the multimeter to the outer, positive terminal of the ignition coil. Turn the reading dial on the multimeter to ohms to measure resistance of the primary pickup coil. (The Greek letter omega denotes ohms.)

What happens when pick up coil goes bad?

A pickup coil that has failed, or is about to, may also cause engine stalling and an inability to accelerate smoothly because the fuel injectors are not firing properly. Engine stalling will occur as the vehicle warms up with rough idling being the first clue that a stall is about to happen.

Can you test a ignition module?

Can you test an ignition control module? Yes, You can definitely test an ignition control module and using a multimeter is one of the fastest way to do so. What does the ignition control module do? The Ignition Control Module or ICM is nothing more than a switch per se that turns the ignition system “On” or “Off”.

How do you diagnose a bad win module?

The WIN module is the module that connects to the start button behind the dash. Other symptoms of the WIN module going bad are occasional “key FOB not detected”, dead dash (no idiot lights), crank for 20 seconds and no start, and even dying while driving but that’s more rare.

What happens when a ignition module goes bad?

a faulty ignition module can affect ignition timing, resulting in an engine that misfires and runs rough. the engine may also run well at low speed, but won’t accelerate well. 3. stalling: a failing ignition module can occasionally prevent the engine from getting spark, causing it to stall.

What kind of bushing does a Duraspark 2 have?

This article refers to the Duraspark II control module with a BLUE strain relief bushing, one 4-pin connector, and one 2-pin connector. Another version of the system has an additional 3-pin wiring connector, and two YELLOW strain relief bushings.

How does the Duraspark 2 engine module work?

The module hold a fixed dwell time, and features automatic retard while cranking to reduce the load on the starter motor. The high voltage ignition coil, wider spaced terminals of the distributor cap, and 8mm silicone insulated high tension wires permit the use of wider spark plug gaps.

When did the Duraspark ignition system come out?

The Duraspark II ignition system debuted in 1976 with the intent to make substantial increases in secondary voltage and extend system maintenance intervals. Spark plug gaps were widened to take advantage of the heightened current and to prolong spark plug life.

How is a Duraspark 2 breaker point ignition connected?

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. The Duraspark II distributor cap is larger in diameter to allow the high tension terminals to be spaced farther apart.
