1. Verify the Ignitor Coil Installation:
* Correct Installation: Double-check that the new ignitor coil is correctly seated and connected. A loose connection or incorrect polarity can prevent it from working. Consult a wiring diagram for your specific model to ensure you have the positive and negative terminals connected correctly.
* Coil Functionality: While you've replaced it, it's possible the *new* coil is faulty. You might need to test it with an ohmmeter to check its resistance (check your shop manual or online resources for the correct resistance values for your coil).
2. Check the Ignition Switch:
* Power to the Coil: With the key in the "ON" position, use a test light or multimeter to check for power at the coil's positive terminal. If there's no power, the problem is likely in the ignition switch circuit or wiring between the switch and the coil.
3. Inspect the Wiring:
* Corrosion and Breaks: Carefully inspect all wires leading to and from the ignitor coil, the distributor, and the ignition switch. Look for broken wires, corrosion, or loose connections. Pay close attention to the high-voltage wires. Even a small crack in the insulation can cause a short or prevent spark.
* Ground Connections: Ensure all ground connections in the ignition system are clean and tight. A poor ground can severely affect the system's ability to produce a spark.
4. Test the Distributor:
* Points (if equipped): If your 1964 Galaxy uses points and a condenser, these could be worn, burned, or improperly gapped. Check their condition and adjust or replace as needed.
* Rotor: The rotor inside the distributor cap may be cracked or worn. Inspect it visually for damage.
* Distributor Cap: Check the distributor cap for cracks or carbon tracking. A faulty cap can prevent spark delivery.
5. Check the Condenser (if applicable): A bad condenser can prevent the coil from functioning correctly. It should be tested with an ohmmeter if you have points-type ignition.
6. Check the Voltage Regulator:
While less likely, a faulty voltage regulator can affect the ignition system's performance by not supplying the correct voltage to the coil.
7. Consider the Ballast Resistor (if applicable): Some ignition systems use a ballast resistor in series with the coil. This resistor is used to reduce the current during cranking to protect the coil from excessive current. If this resistor fails, it could also prevent sparking.
Tools You'll Need:
* Test light or multimeter
* Wire diagram for your 1964 Ford Galaxy
* Ohmmeter (for testing coil and condenser)
* Socket wrench and screwdriver set
Important Note: Working with automotive electrical systems can be dangerous. Always disconnect the negative battery terminal before starting any electrical work to prevent shocks or short circuits. If you are not comfortable working on automotive electrical systems, it is best to take your car to a qualified mechanic.
