2004 Chevy Silverado Ignition Wiring Diagram – First, we will look at the different types of terminals that are found on the ignition switch. These are terminals for the Ignition, Coil, or Accessory. Once we have identified the purpose of these terminals then we can identify the different parts in the ignition wiring. Then, we will discuss the functions for the Ignition switch and the Coil. We will then discuss the functions of the Ignition switch and Coil.
The ignition switch’s terminals
An ignition switch is made up of three switches. They are responsible for supplying the battery’s power to several locations. The first switch is the one that supplies the choke with power, while the second toggles the ON/OFF status of the ignition switch. Each manufacturer has their own color-coding system, which we’ll discuss in a subsequent article. OMC utilizes the same system. A connector can be added to the ignition switch in order to connect an electronic Tachometer.
Although some ignition switch terminals do not have the original design The numbering might not be in line with the diagram. To ensure that your wires are connected to the switch, it is recommended to check their continuity. This can be accomplished using an inexpensive multimeter. Once you are satisfied with the integrity of the wires it is time to install the new connector. If your vehicle has an original factory-supplied ignition switch (or a wiring loom) The wiring loom may differ from that in your vehicle.
It is essential to know how the ACC outputs and the auxiliary outputs function in order to connect them. The ACC/IGN connections function as the default connections on the ignition switch. The START/IGN terminals are connected to the radio or stereo. The ignition switch is responsible for turning the car’s engine to and off. The ignition switch terminals on older cars are labeled with the initials “ACC” and “ST” (for the individual magneto wires).
Terminals for coil
Understanding the terminology that is used is the initial step in determining the kind of ignition coil you need. The diagram of the basic ignition wiring depicts various connections and terminals. There are two primary and one secondary. You must determine the type of coil you own by examining the voltage at the primary terminal S1. S1 must also be subjected to resistance tests to determine if it is an A or B coil.
The negative of the chassis must be connected to the side of low-tension. This is what’s called the ground in the wiring diagram for ignition. The high-tension supply supplies positively directly to spark plugs. To reduce the noise, the coil’s metal body is required to be connected to the chassis. It is not necessary to connect the coil electrically. The ignition wiring diagram will also indicate the connection of the positive coil terminals. In certain instances it is recommended to conduct a scan at your local auto parts shop can help you identify defective ignition coils.
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 negative terminal. The black wire connects with the contact breaker. To verify the connections between the two wires use a paperclip to remove them off the housing. It is also important to make sure that the connections are not bent.
Accessory terminals
The wiring diagrams for the ignition show the different wires used to power the various components of the car. There are usually four terminals with color codes that are connected to each component. For accessories, red stands the starter solenoid’s color, yellow is for battery and blue for accessories. The “IGN” terminal can be used to start the car , and also to operate the wipers, as well as other operating features. The diagram shows the connection of the ACCas well as ST terminals.
The terminal BAT holds the battery. The battery is vital to allow the electrical system to get started. Also, the switch won’t turn on without the battery. If you’re not sure of where your car’s battery is located, you can look at your wiring diagram to figure out how to locate it. The accessory terminals in your car are connected to the battery and the ignition switch. The BAT terminal is connected to the battery.
Certain ignition switches come with the “accessory” setting that allows users to regulate their outputs without needing to turn on the ignition. In some cases, users may want to utilize the auxiliary output separately from the ignition. For the auxiliary output to be used, plug in the connector to the same color as that of the ignition. Then connect it with the ACC end of the switch. Although this is a great option, there’s a thing to be aware of. A majority of ignition switches feature the ACC position when the car is in the ACC mode and a START mode when the switch is in IGN.
