What is an Ignition Wiring Diagram?
An ignition wiring diagram is a schematic drawing that shows the electrical connections and wiring configurations of components in an ignition system. It is a vital tool for troubleshooting and diagnosing ignition system problems in any vehicle. The 98 Honda Civic ignition wiring diagram is specifically designed to help diagnose and repair issues with the ignition system in this particular model of the Honda Civic.
Before we dive into the specifics of the 98 Honda Civic ignition wiring diagram, let’s have a quick look at the ignition system in general.
The Ignition System
The ignition system is what starts your car’s engine. It does this by generating a high voltage spark that ignites the fuel in the engine’s cylinders. The system is made up of several components, including the battery, ignition switch, starter motor, distributor, ignition coil, spark plugs, and wiring. Each of these components plays a specific role in starting the engine and keeping it running.
The Battery
The battery is the main source of power for the entire electrical system in your car. It provides power to everything from the starter motor to the headlights.
The battery is located in the engine bay and is connected to the starter motor and the alternator through a series of cables.
The Ignition Switch
The ignition switch is what you use to start your car. When you turn the key, it sends an electrical signal to the starter motor and the engine starts to crank.
There is a push button start version of the Honda Civic, but this article will focus on the ignition switch version.
The Starter Motor
The starter motor is responsible for turning the engine over when you turn the key in the ignition. It is connected to the battery and the ignition switch via a series of cables.
The Distributor
The distributor is responsible for distributing the high voltage spark generated by the ignition coil to the correct spark plug at the correct time. It is located on the engine and is driven by the camshaft.
The Ignition Coil
The ignition coil is what generates the high voltage spark that ignites the fuel in the engine’s cylinders. It is connected to the battery and the distributor via a series of cables.
The Spark Plugs
The spark plugs are what actually ignite the fuel in the engine’s cylinders. There is one spark plug for each cylinder in the engine. They are connected to the distributor via a series of cables.
