Did you just purchase a Chevy 350 engine or are you planning to upgrade your current engine? If so, it’s important to know how to wire the ignition coil correctly. The ignition coil is responsible for generating the spark that ignites the fuel in the engine. In this article, we will discuss everything you need to know about the Chevy 350 ignition coil wiring diagram.
What is an Ignition Coil?
Before diving into the wiring diagram, let’s first understand what an ignition coil is. The ignition coil is an essential component of an internal combustion engine. It is responsible for converting low voltage from the battery into high voltage required to ignite the fuel. The high voltage is delivered to the spark plugs via the distributor to ignite the fuel mixture in the combustion chamber.
How Does an Ignition Coil Work?
An ignition coil is essentially a transformer. It consists of two coils of wire wrapped around a magnetic core. One coil is known as the primary coil, and the other is the secondary coil. The primary coil is connected to the battery, and the secondary coil is connected to the spark plugs.When the ignition switch is turned on, current flows from the battery through the primary coil, creating a magnetic field around the core. When the current is interrupted, the magnetic field collapses, inducing a high voltage in the secondary coil. This high voltage is then delivered to the spark plugs, igniting the fuel mixture.
Chevy 350 Ignition Coil Wiring Diagram
Now that we understand how an ignition coil works let’s discuss the wiring diagram for the Chevy 350 engine. The wiring diagram for the Chevy 350 ignition coil is relatively simple. It consists of three wires; the B+ wire, the ignition wire, and the tach wire.The B+ wire connects to the positive terminal of the battery and provides power to the ignition coil. The ignition wire connects to the ignition switch and provides power to the coil when the switch is turned on. The tach wire connects to the tachometer and provides a signal to measure engine RPM.
Step-by-Step Wiring Instructions
To wire the ignition coil correctly, follow the step-by-step instructions below:Step 1: Disconnect the negative terminal of the battery to prevent accidental shock.Step 2: Locate the ignition coil on the engine. It is typically mounted on the intake manifold or near the distributor.Step 3: Connect the B+ wire to the positive terminal of the ignition coil.Step 4: Connect the ignition wire to the ignition terminal on the coil.Step 5: Connect the tach wire to the tachometer terminal on the coil.Step 6: Reconnect the negative terminal of the battery.
FAQs
What happens if the ignition coil is wired incorrectly?
If the ignition coil is wired incorrectly, it can cause a range of issues, including poor engine performance, misfires, and damage to the coil or other components. Ensure you follow the wiring diagram correctly and double-check all connections.
What are some signs of a faulty ignition coil?
Some signs of a faulty ignition coil include engine misfires, rough idling, decreased fuel economy, and difficulty starting the engine. If you suspect your ignition coil is faulty, it’s best to get it checked by a mechanic.
Can I test the ignition coil with a multimeter?
Yes, you can test the ignition coil with a multimeter. Set the multimeter to the ohms setting and test the resistance between the two primary coil terminals. The resistance should be within the manufacturer’s recommended range. You can also test the secondary coil by checking the resistance between the coil tower and the center electrode of the coil.In conclusion, wiring the ignition coil correctly is crucial for the proper functioning of your engine. Follow the wiring diagram and instructions provided in this article to ensure your Chevy 350 engine runs smoothly. If you have any questions or concerns, don’t hesitate to consult a mechanic or professional.
