2004 Silverado Ignition Switch Wiring Diagram – Let’s begin by examining the different types and purposes of the terminals that are found on the ignition switches. These terminals are for the Ignition button, Coil and Accessory. Once we know what these terminals do then we can determine the various components in the ignition wiring. Then, we will discuss the functions as well as the Coil. We will then discuss the functions of the ignition switch and Coil.
The terminals are for ignition switches.
An ignition switch is composed of three different switches. They are responsible for supplying the battery’s power to various destinations. The first switch provides power to the choke when pushed, and the second is the position of the ignition switch’s ON/OFF. Different manufacturers employ various color codes for the various conductors. This is described in another article. OMC uses this system. A connector can be added to the ignition switch to add a digital Tachometer.
Even though some of the ignition switch terminals might not be original, the numbers of the terminals may not match the diagram. Check the integrity of the wires to ensure that they are connected to the ignition switch correctly. This can be accomplished with a simple multimeter. When you’re satisfied that the wires are in good continuity and you are able to connect the new connector. The wiring loom of an ignition switch that is factory-supplied will be different than the one you have in your vehicle.
You must first understand the way that ACC outputs and auxiliary outputs work in order to connect them. The ACC terminals and IGN terminals are the default connections to your ignition switch. The START and IGN connections are the main connections for radio and stereo. The ignition switch is accountable to turn the car’s engines on and off. Older vehicles have ignition switch’s terminals that are labeled “ACC” or “ST” (for individual magnetowires).
Terminals for coil
Understanding the terminology used is the initial step to determining the type of ignition coil. In a typical diagram of the wiring for ignition, you will see various connections and terminals, such as two primary and two secondary. Each coil is equipped with a distinct operating voltage. To determine what kind of coil you own first, you need to test the voltage at S1, which is the primary terminal. S1 must also go through resistance tests to determine if it are an A or B coil.
The coil’s low-tension side must be connected to the chassis positively. This is what you see on the wiring diagram. The high tension side provides positively directly to the spark plugs. The aluminum body of the coil needs to be linked to the chassis to prevent it from being smothered, but it isn’t electrically required. The wiring diagram of the ignition will show you how to connect the terminals of the positive or negative coils. Sometimes, a check at an auto parts shop can identify a problem with the ignition wire.
The black-and-white-striped wire from the harness goes to the negative terminal. The white wire has a black color and goes to the terminal opposite. The black wire connects to the contact breaker. To test the wires’ connections use a paperclip to remove them out of the housing. Also, make sure to check that the terminals haven’t been bent.
Accessory Terminals
Ignition wiring diagrams depict the various wires that are used to power various components. There are usually four different colored terminals for each component. Red is for accessories while yellow is the battery, while green is for the starter solenoid. The “IGN terminal lets you start the car, manage the wipers or other operation features. The diagram illustrates how to connect ACC or ST terminals, and other.
The terminal BAT is the connection for the battery. The electrical system won’t start in the event that the battery isn’t connected. Additionally, the switch won’t start. You may refer to the wiring diagram if unsure where your car’s batteries are located. The ignition switch as well as the battery are connected through the accessory terminals. The BAT connector is connected to the battery.
Some ignition switches come with an additional “accessory position” that lets users modify their outputs independent of the ignition. Customers sometimes want an auxiliary output that can be used separately from the ignition. The auxiliary output is utilized to connect the connector with the same colors as the ignition, and then attaching it to the ACC terminal of the switch. While this is an excellent feature, there’s one thing you should know. The majority of ignition switches are set up to have an ACC status when the car’s in the ACC or START position.
