2002 Chevy Silverado Ignition Switch Wiring Diagram – The first step is to take a look at the different types of terminals that are used in the ignition switch. These terminals comprise the Ignition switch and Coil as well as the Accessory. Once we have identified what these terminals do then we can be able to identify the various parts of the ignition wiring. In addition, we will discuss the roles of the Ignition switch, as well as the Coil. After that we will discuss the Accessory Terminals.
Terminals for ignition switches
An ignition switch has three separate switches that feed the battery’s power to various destinations. The choke is powered by the first switch. The second switch is responsible for the ON/OFF switch of the ignition switch. Different manufacturers employ different color codes for various conductors. This is described in a separate article. OMC employs this system. An additional connector is included in the ignition switch to allow connecting a Tachometer.
While many ignition switch terminals could not be authentic, the numbering of the terminals may not match the diagram. To make sure that your wires are properly connected to the switch you must verify their continuity. This can be done using a cheap multimeter. When you’re happy with the connection it’s time to connect the new connector. If your car has an original ignition switch supplied by the factory (or an electrical loom) The wiring loom might differ from the one in your car.
It is important to know the differences between the ACC and auxiliary outputs. The ACC, IGN and START terminals are your default connections to the ignition switch. They also function as the primary connections to the radio and stereo. The ignition switch turns the car’s engine ON and OFF. The ignition switch terminals on older cars are labeled with the alphabets “ACC” as well as “ST” (for the individual magneto wires).
Terminals for coil
Understanding the terms used is the first step towards determining the type of ignition coil. In a simple diagram of the wiring for ignition, you will see several different terminals and connections, including two primary and two secondary. Each coil has a specific operating voltage. To determine which type of coil you’ve got, the first step is to determine the voltage at S1, which is the primary terminal. To determine if the coil is an A, C, or B coil, it is recommended to also check the resistance of S1.
The low-tension end of the coil should be connected to the chassis”negative. This is exactly what you can see on the wiring diagram. The high-tension side connects the spark plugs to a positive. To prevent noise, the coil’s body metal must be connected to the chassis. It’s not necessary for electrical use. The wiring diagram of the ignition will demonstrate how to connect the terminals of the positive or negative coils. In certain instances you’ll discover that the ignition coil is damaged and is easily identified with scans at an auto parts store.
The black-and-white-striped wire from the harness goes to the negative terminal. The terminal that is negative is served by the black trace attached to the white wire. The black wire is connected to the contact breaker. To test the wires’ connections, use a paperclip to lift them from the housing. It’s also essential to ensure that the terminals do not bend.
Accessory terminals
The ignition wiring diagrams illustrate the various wires that provide power to the various parts of the vehicle. Typically there are four distinct colored terminals for each part. Red is used to indicate accessories, yellow the battery, and green for the starter solenoid. The “IGN terminal is used to start the car, operating the wipers, and for other functions. The following diagram illustrates how to connect the ACC terminal and ST terminals to various components.
The terminal BAT is the connection to the battery. Without the battery the electrical system can not get started. The switch won’t turn on if there is no battery present. To locate your car’s battery, check your wiring diagram. The accessory terminals in your car connect to the battery and the ignition switch. The BAT terminal is connected to the battery.
Some ignition switches come with a separate “accessory” position, in which users can control their outputs with no ignition. Some customers prefer to use an auxiliary output that is independent of the ignition. You can utilize the auxiliary input by connecting the connector to the ACC terminal. This option is useful, but it has one key distinction. Some ignition switches are configured to be in an ACC position when the vehicle has moved into the ACC position. They also will be in START mode when the vehicle has entered the IGN position.
