Schematic 5 Prong Ignition Switch Wiring Diagram

The ignition switch is a vital component in any vehicle. Without it, the car won’t start. The ignition switch is a component of the car’s electrical system that allows the battery to power up the rest of the components in the car. It is typically located near the steering column and looks like a large keyhole. Most modern cars have a 5 prong ignition switch as opposed to the more traditional 3 prong switch. The 5 prong ignition switch offers additional security and convenience features compared to its predecessor.

To understand how a 5 prong ignition switch works, it is important to first identify its different positions. The most common positions in a 5 prong ignition switch are ‘off’, ‘accessory’, ‘ignition’, ‘start’, and ‘run’. When the switch is in the ‘off’ position, all electricity from the battery is shut off and no current can flow through the system. In the ‘accessory’ position, only certain components such as the radio and some lights can be powered. The ‘ignition’ position allows the engine to receive fuel and spark so that it can start. The ‘start’ position allows the starter motor to turn the engine over for a few seconds to allow it to start. Finally, the ‘run’ position supplies power to all the components in the car including the air conditioning, headlights, and other accessories.

In addition to its different positions, a 5 prong ignition switch also has different wire colors. These wire colors can vary depending on the make and model, but the most common wire colors are red, black, green, yellow, and white. The red wire is usually connected to the positive terminal of the battery and supplies power to the ignition switch. The black wire is connected to the negative terminal of the battery and serves as a ground. The green wire is connected to the starter motor and allows the engine to turn over. The yellow wire is connected to the coil and supplies power to the spark plugs. The white wire is connected to the ignition switch and sends the signal to the starter motor when the key is turned.

When wiring a 5 prong ignition switch, it is important to follow the proper procedure to ensure that everything is properly connected. First, the red wire should be connected to the positive terminal of the battery. Next, the black wire should be connected to the negative terminal of the battery. Then, the green wire should be connected to the starter motor, the yellow wire should be connected to the coil, and the white wire should be connected to the ignition switch. Once all the wires are connected, the switch should be tested to make sure that it is working properly.

If the switch is not working properly, there are several troubleshooting steps that can be taken to identify and fix the problem. The first step is to check all the wires to make sure that they are properly connected. If everything is connected properly, then the switch should be tested again to see if it is still not working. If the switch is still not working, then the next step is to check the continuity of the wires with a multimeter. This will help to identify any faulty connections in the circuit. If these steps do not resolve the issue, then the switch might need to be replaced.

A faulty ignition switch can cause a variety of symptoms including difficulty starting the car, strange noises coming from the engine, or the car not starting at all. If you experience any of these symptoms, it is important to have the switch checked and possibly replaced to avoid any further damage to the vehicle. Replacing an ignition switch can cost anywhere from $50 to $200, depending on the make and model.

Overall, the 5 prong ignition switch is an important component in any car. It is responsible for supplying power to the engine and other components so that the car can start and run properly. Understanding how a 5 prong ignition switch works and how to wire one properly is essential for keeping your car running smoothly. If the switch is not working properly, it is important to identify and address the issue quickly to avoid any further damage to the vehicle.
