If you are trying to upgrade or modify your vehicle’s ignition system, installing a Duraspark ignition module can be a great option. However, understanding and installing its wiring diagram can be a daunting task, especially for beginners. In this article, we will cover everything you need to know about the Duraspark wiring diagram.
What is a Duraspark Wiring Diagram?
The Duraspark wiring diagram is a schematic representation of the ignition system of a vehicle equipped with the Duraspark ignition module. The Duraspark module was introduced by Ford in the mid-1970s and has since become a popular option for upgrading and modifying ignition systems in various vehicles.
The Duraspark system features an electronic control module (ECM) that controls the dwell time and spark timing of the ignition system. It also uses a magnetic pickup coil and a distributor that deliver the spark to the cylinders in the correct firing order.
The Components of a Duraspark Wiring Diagram
The Duraspark wiring diagram consists of several components, each with its specific function. The components include:
Component | Function |
---|---|
Electronic Control Module (ECM) | To control the dwell time and spark timing |
Distributor | To deliver the spark to the cylinders in the correct firing order |
Magnetic Pickup Coil | To sense the position of the distributor shaft and signal the ECM to fire the spark plug |
Ignition Coil | To convert the battery voltage into high-voltage electricity and deliver it to the spark plugs |
Ballast Resistor | To reduce the voltage to the coil during normal operation and prevent overheating |
Understanding the Duraspark Wiring Diagram
Before installing a Duraspark wiring diagram, it is important to understand how it works. The wiring diagram consists of several colored wires that connect the various components of the ignition system. Each wire has its specific function and location in the system.
The Color Codes of a Duraspark Wiring Diagram
The color codes of a Duraspark wiring diagram are as follows:
Wire Color | Function |
---|---|
Orange | To supply power to the system from the ignition switch |
Red | To supply power to the system from the battery |
White | To connect the magnetic pickup coil to the ECM |
Green | To connect the Tachometer to the system |
Black | To ground the system |
Yellow | To connect the ignition coil to the system |
Installation of the Duraspark Wiring Diagram
Once you have understood the Duraspark wiring diagram, the installation process becomes more straightforward. The following steps will guide you through the installation process:
Step 1: Disconnect the Battery
Before starting the installation process, disconnect the battery to prevent any electrical shock or damage to the system.
Step 2: Remove the Old Ignition System
Remove the old distributor and ignition system from your vehicle, including the wiring harnesses, ballast resistor, and ignition coil.
Step 3: Install the Duraspark Ignition Module
Install the Duraspark ignition module by connecting it to the distributor and magnetic pickup coil using the white and yellow wires.
Step 4: Connect the Power Wires
Connect the orange wire to the ignition switch and the red wire to the battery.
Step 5: Connect the Ground Wire
Connect the black wire to the ground.
Step 6: Connect the Tachometer
Connect the green wire to the tachometer if your vehicle has one.
Step 7: Test the System
Reconnect the battery and test the system to ensure that it is working correctly.
