The Pertronix Ignitor is an electronic ignition system designed as a replacement for points-style ignition systems in 12-volt applications. The documentation details a specific installation procedure, compatibility considerations, and wiring instructions. This article provides a comprehensive overview of installing the Ignitor, based solely on the provided manual. The system is intended for use with “points style” coils and is not compatible with “HEI” type coils. The documentation emphasizes the ability to retain existing points, condensers, and hardware as backup components.
System Overview and Compatibility
The Pertronix Ignitor is designed for 12-volt positive ground systems. It functions by electronically triggering the ignition coil, eliminating the need for mechanical points and a condenser. The system aims to provide a more reliable and consistent spark, potentially improving engine performance.
The documentation explicitly states compatibility with “points style” coils. However, it firmly advises against using “HEI” (High Energy Ignition) type coils with the Ignitor system. This incompatibility is a critical consideration during installation and component selection. The documentation does not provide details regarding specific coil specifications beyond this distinction.
Pre-Installation Inspection
Prior to installation, the documentation recommends a thorough inspection of the existing distributor components. This includes the distributor cap and rotor. Users should examine these parts for any signs of wear or damage and replace them as needed. This preventative measure ensures optimal system performance and reliability. The documentation does not specify criteria for determining wear or damage, leaving this assessment to the user’s judgment.
Installation Procedure
The installation process involves several steps, outlined as follows:
- Turn the ignition switch off or disconnect the battery to prevent accidental electrical shock or damage.
- Remove the distributor cap and rotor. The documentation specifically instructs users not to disconnect the spark plug wires during this step.
- Remove the existing points, condenser, and grommet from the distributor.
- Install the Ignitor plate onto the breaker plate and secure it in place. The documentation notes that the Ignitor does not require any modification to the distributor, allowing the removed points, condenser, and hardware to be retained for backup purposes.
- Clean any oil or dirt from the breaker plate and point cam to ensure proper contact and operation.
- Install the magnet sleeve over the distributor shaft and onto the point cam. Rotate the sleeve until a slight locating position is felt before applying pressure. Ensure the sleeve is fully seated.
- Insert both wires from the Ignitor through the hole in the distributor housing. Pull the grommet into place, ensuring the wires do not interfere with any moving parts within the distributor.
- Replace the rotor and distributor cap, ensuring all spark plug wires are securely attached.
- Remove the ignition switch wire from the negative coil terminal.
- Connect the black Ignitor wire directly to the ignition switch wire.
- Connect the Ignitor black/white wire to the negative (-) side of the ignition coil.
- Connect an insulated, AWG 20 copper stranded wire from the positive coil terminal to the positive battery or chassis.
- Ensure that the black/white Ignitor wire and the AWG 20 copper wire are the only wires connected to the coil.
- Reconnect the battery and verify all wires are connected correctly.
- The engine can then be started, and the timing should be set in the conventional manner after the engine has run for a few minutes.
Wiring Considerations
The documentation places significant emphasis on correct wiring. The Ignitor requires specific connections to the ignition switch, coil, and power source. The black Ignitor wire connects directly to the ignition switch wire previously connected to the negative coil terminal. The black/white Ignitor wire connects to the negative side of the ignition coil. A separate, insulated AWG 20 copper stranded wire must be run from the positive coil terminal to the positive battery or chassis.
The documentation explicitly states that only these two wires – the black/white Ignitor wire and the AWG 20 copper wire – should be connected to the coil. This restriction is crucial for proper system operation and prevents potential damage.
Distributor Ground Wire
The documentation includes a reminder to re-attach the distributor ground wire if it was removed during the installation process. Ensuring a secure ground connection is essential for proper system functionality.
Positive Ground Applications
The provided documentation specifically addresses installation procedures for 12-volt positive ground applications. The documentation does not provide information regarding negative ground systems.
Backup System
A notable feature of the Ignitor system, as highlighted in the documentation, is the ability to retain the original points, condenser, and hardware as a backup. Because the Ignitor does not require modification to the distributor, these components remain available for use if the electronic ignition system fails.
Safety Precautions
The documentation begins with a disclaimer regarding liability for money damages, whether direct or consequential. The initial step in the installation procedure emphasizes turning off the ignition switch or disconnecting the battery. This precaution is intended to prevent electrical shock or damage during the installation process.
Conclusion
The Pertronix Ignitor electronic ignition system offers a replacement for traditional points-style ignition systems in 12-volt positive ground applications. Successful installation requires careful adherence to the provided instructions, particularly regarding wiring and compatibility with coil types. The ability to retain original components as a backup provides a degree of redundancy. The documentation stresses the importance of disconnecting the battery before beginning the installation process.
