Harley Ignition Wiring Diagram

Harley Ignition Wiring Diagram – The first step is to take a look at the different types of terminals on the ignition switch. These include terminals that are used for Coil, Ignition Switch, and Accessory. After we’ve identified the purpose of these terminals then we can be able to identify the various parts of the ignition wiring. We will also talk about the functions and the Coil. After that, we will focus on the accessory terminals.

The terminals of the ignition switch

Three switches are located in an ignition switch. Each of these three switches transmits the battery’s current to various places. The first is utilized to turn on the choke through pushing it. Then, the second is for the ON/OFF position. Different manufacturers employ different colors for different conductors. This is explained in a separate article. OMC utilizes this approach. A connector is also included inside the ignition switch to allow attaching the tachometer.

While most ignition switch terminals are not original, the numbering for each might not be consistent with the diagram. Before plugging into the ignition switch ensure that you check the continuity. This can be done using an inexpensive multimeter. After you’ve confirmed the continuity of the wires you are able to connect the connector. If your vehicle has an original factory-supplied ignition switch (or an electrical loom) the wiring loom will differ from that in your car.

Knowing how the ACC outputs connect to the other outputs in your vehicle is crucial. The ACC terminals as well as the IGN terminals are the standard connections for your ignition switch. The START and IGN connections are the primary connections for radio and stereo. The ignition switch switches the engine of your car ON and off. Older vehicles have ignition switch’s terminals that are labeled “ACC” or “ST” (for individual magnetowires).

Terminals for Coil

To identify the kind of ignition coil you need to know the step is to learn the definition of. In a simple ignition wiring diagram, you will see several different terminals and connections, including two primary and two secondary. You must determine the type of coil you are using by testing the voltage on the primary terminal, S1. It is also recommended to check S1 for resistance to determine if it’s a Type A, B, or C coil.

The coil’s low-tension side must be connected with the chassis positive. This is what is known as the ground for the wiring for ignition. The high tension side supplies positive power directly to the spark plugs. The coil’s aluminum body needs to be linked to the chassis for suppression but isn’t required. The diagram of the ignition wiring will also show the connections of the positive coil terminals. Sometimes, an inspection at an auto parts shop can detect a defective ignition wire.

The black-and-white-striped wire from the harness goes to the negative terminal. The negative terminal is served by the black trace connected to the white wire. The contact breaker is attached to the black wire. You can examine the connections with a pencil to pull the wires out of the housing. Also, make sure to verify that the connections have not been bent.

Accessory terminals

Diagrams of the ignition wiring illustrate the wires that power various parts of the vehicle. Typically, there are four different colors-coded terminals that are used for each component. To identify accessories, red stands the starter solenoid’s color, yellow is for battery and blue for accessories. The “IGN” terminal is used for starting the car, controlling the wipers and other functions. The following diagram illustrates how to connect the ACC terminal as well as the ST terminals to other components.

The terminal BAT connects the battery to the charger. The electrical system will not start without the battery. Additionally, the switch will not be able to turn on without the battery. It is possible to view the wiring diagram of your car to see where the batteries of your car are situated. The accessory terminals of your car are connected to the battery and the ignition switch. The BAT connector connects to your battery.

Certain ignition switches come with an “accessory” setting that permits users to control their outputs without having to use the ignition. Users may wish to use the auxiliary output independently of the ignition. To make use of the auxiliary output, connect the connector in identical colors to the ignition connecting it to the ACC terminal on the switch. This is a great convenience feature however, there’s one distinction. A majority of ignition switches feature an ACC position when your car is in ACC mode and a START position when it is in IGN.
