How to Check Engine Coil on a 1966 Car
The engine coil is a critical component of a car’s ignition system. It converts the low-voltage current from the battery into a high-voltage current that is required to create a spark at the spark plugs. If the engine coil is not working properly, the car will not be able to start or run. There are a few simple steps that you can follow to check the engine coil on a 1966 car.
Step 1: Identify the Engine Coil
The engine coil is usually located on the top of the engine, near the distributor. It is a cylindrical-shaped component with two terminals. The positive terminal is usually marked with a “+” sign, and the negative terminal is usually marked with a “-” sign.
Step 2: Disconnect the Coil Wires
Before you can test the engine coil, you need to disconnect the coil wires. There are two coil wires: one that connects to the positive terminal of the coil, and one that connects to the negative terminal of the coil. Use a pair of pliers to carefully remove the coil wires from the terminals.
Step 3: Set Up a Multimeter
You will need a multimeter to test the engine coil. Set the multimeter to the resistance setting. The resistance setting is usually denoted by the Greek letter “Ω”.
Step 4: Connect the Multimeter to the Coil Terminals
Connect one probe of the multimeter to the positive terminal of the coil, and connect the other probe of the multimeter to the negative terminal of the coil.
Step 5: Take a Resistance Reading
The multimeter will display the resistance reading between the two terminals. The resistance reading should be between 0.5 ohms and 1.5 ohms. If the resistance reading is outside of this range, the engine coil is likely faulty.
Additional Tips
- If you do not have a multimeter, you can check the engine coil by using a spark tester. A spark tester is a simple device that can be purchased at most auto parts stores. To use a spark tester, connect one end of the spark tester to the positive terminal of the coil, and connect the other end of the spark tester to the negative terminal of the coil. Then, hold the spark tester near the engine block. If the spark tester does not spark, the engine coil is likely faulty.
- If you have replaced the engine coil and the car still does not start or run, there may be another problem with the ignition system. You should consult with a qualified mechanic to diagnose and repair the problem.
Conclusion
Checking the engine coil on a 1966 car is a simple process that can be completed in a few minutes. If you suspect that the engine coil is faulty, follow the steps outlined in this article to test the coil and determine if it needs to be replaced.
