By the end of this article, you'll have a solid understanding of how the wiring system works on your Shovelhead.

The Electrical System

The electrical system of the 1980 Harley Davidson Shovelhead is relatively simple. It consists of a few major components: * The battery * The ignition switch * The starter motor * The alternator * The voltage regulator * The spark plugs * The wiring harness Let's take a closer look at each of these components.

The Battery

The battery is the source of power for the electrical system. It provides power to the ignition system, the starter motor, and the lights. The battery is also used to store energy that is generated by the alternator.

The Ignition Switch

The ignition switch is used to turn the motorcycle on and off. It also provides power to the ignition system. The ignition switch is located on the handlebars.

The Starter Motor

The starter motor is used to start the engine. It is powered by the battery. The starter motor is located under the engine.

The Alternator

The alternator is used to generate electricity. It is powered by the engine. The alternator is located on the left side of the engine.

The Voltage Regulator

The voltage regulator is used to keep the voltage from the alternator at a constant level. The voltage regulator is located on the left side of the engine.

The Spark Plugs

The spark plugs are used to ignite the fuel in the engine. The spark plugs are located in the heads of the engine.

The Wiring Harness

The wiring harness is a collection of wires that connect all of the components of the electrical system. The wiring harness is located under the seat of the motorcycle.

Understanding the Wiring Diagram

The wiring diagram is divided into two sections: the primary circuit and the secondary circuit. The primary circuit is the circuit that provides power to the ignition system. The secondary circuit is the circuit that provides power to the spark plugs. The primary circuit is made up of the following components: * The battery * The ignition switch * The starter motor * The alternator * The voltage regulator The secondary circuit is made up of the following components: * The spark plugs * The wiring harness The following is a brief explanation of how the wiring diagram works: * The battery provides power to the ignition switch. * The ignition switch turns on the starter motor. * The starter motor turns the engine over. * The alternator generates electricity. * The voltage regulator keeps the voltage from the alternator at a constant level. * The spark plugs ignite the fuel in the engine.

Troubleshooting

If you're having problems with the electrical system on your Shovelhead, the wiring diagram can be a valuable tool for troubleshooting. By following the wiring diagram, you can trace the problem to its source. Here are a few tips for troubleshooting electrical problems on your Shovelhead: * Check the battery to make sure it's properly charged. * Check the fuses to make sure they're not blown. * Check the wiring harness for any damaged or loose wires. * Check the ignition switch to make sure it's working properly. * Check the starter motor to make sure it's working properly. * Check the alternator to make sure it's generating electricity. * Check the voltage regulator to make sure it's keeping the voltage at a constant level. If you're still having problems after troubleshooting, it's best to take your Shovelhead to a qualified mechanic.
