Removing the Old Ignition System
Begin by locating the existing ignition system components, including the coil, distributor, and any associated wiring. Carefully remove these components, taking note of how they are connected for reference.
- Disconnect the battery cables.
- Remove the old ignition coil by unscrewing it from its mounting location.
- Take out the distributor cap and rotor.
- Unplug any wiring connected to the ignition system.
Installing the MSD Ignition System
With the old ignition system removed, it’s time to install the new MSD components. Follow these steps closely to ensure proper installation.
- Position the MSD ignition coil in the same location as the old coil and secure it with screws.
- Connect the power and ground wires to the coil, ensuring a solid connection.
- Install the MSD distributor by aligning it with the engine block and securing it in place.
- Attach the rotor and distributor cap, ensuring they fit snugly.
Wiring the MSD Ignition System
Proper wiring is crucial for the MSD ignition system to function correctly. Follow these wiring steps for a successful installation.
- Refer to the MSD wiring diagram specific to your model for accurate connections.
- Connect the ignition switch wire to the MSD ignition box.
- Run the tachometer wire from the MSD box to the tachometer gauge if applicable.
- Ensure all connections are secure and insulated using electrical tape or heat shrink tubing.
Final Checks and Reconnection
Before reconnecting the battery, double-check all connections and components. Ensure that there are no loose wires or exposed connections that could cause issues.
Once you are satisfied with the installation, reconnect the battery and prepare to start the engine.
Testing the New Ignition System
Start the engine and listen for any irregular sounds. The MSD ignition system should provide a smooth and steady performance. If the engine does not start or runs poorly, recheck all connections and components.
Troubleshooting Common Issues
- If the engine won’t start, verify that the battery is fully charged and all connections are tight.
- Check the ignition timing to ensure it is set correctly.
- If experiencing misfires, inspect the spark plugs and wires for damage.
