Harley Davidson motorcycles are known for their classic designs and powerful engines. The 1966 model is no exception, and it is considered one of the most iconic Harley Davidson motorcycles. This article will provide you with a comprehensive guide to the wiring diagram for a 1966 Harley Davidson motorcycle, along with frequently asked questions and tables for your convenience.

Overview of the Wiring Diagram

The wiring diagram for a 1966 Harley Davidson motorcycle is a schematic representation of the electrical system of the motorcycle. It shows the various components of the system and how they are connected to each other. The wiring diagram is important for troubleshooting electrical problems on the motorcycle and for performing repairs and modifications.

The wiring diagram consists of several parts:

Part Description
Battery The power source for the electrical system.
Ignition switch The switch that turns on the ignition system.
Coil The component that generates the high voltage needed for the ignition system.
Distributor The component that distributes the high voltage to the spark plugs.
Generator The component that generates the electrical power for the motorcycle.
Regulator The component that regulates the electrical power output from the generator.
Starter motor The component that starts the engine.

Battery

The battery is the power source for the electrical system of the motorcycle. It stores electrical energy and supplies it when the engine is not running. The battery is connected to the ignition switch, and the switch controls the flow of electricity to the rest of the system.

The wiring diagram shows the connection between the battery and the ignition switch, as well as the connection between the battery and the rest of the system. It is important to check the battery regularly and replace it when it is damaged or worn out.

It is also important to ensure that the battery is properly charged. The generator or alternator charges the battery when the engine is running. The wiring diagram shows the connection between the generator or alternator and the battery.

FAQ:

  1. How often should I check my motorcycle’s battery?
  2. You should check your motorcycle’s battery at least once a month. If the motorcycle is not used for an extended period, you should check the battery before starting the engine.

  3. How do I know if my motorcycle’s battery is fully charged?
  4. You can use a voltmeter to measure the voltage of the battery. A fully charged battery should have a voltage between 12.6 and 12.8 volts.

Ignition System

The ignition system is responsible for starting the engine and maintaining its operation. The wiring diagram shows the connection between the ignition switch, the coil, and the distributor. The ignition switch controls the flow of electricity to the coil, which generates the high voltage needed for the ignition system. The distributor distributes the high voltage to the spark plugs, which ignite the fuel in the engine.

It is important to check the ignition system regularly and replace any damaged or worn out components. A faulty ignition system can cause starting problems and engine misfires.

FAQ:

  1. How do I troubleshoot a faulty ignition system?
  2. You can use a test light or voltmeter to check the voltage at various points in the ignition system. If the voltage is lower than expected or nonexistent, there may be a problem with one of the components.

  3. How do I know if my motorcycle’s ignition system is working properly?
  4. You can check the spark plugs for signs of wear or fouling. If the spark plugs are in good condition, the ignition system is likely working properly.

Generator and Regulator

The generator or alternator is responsible for generating electrical power for the motorcycle. The wiring diagram shows the connection between the generator or alternator and the regulator. The regulator regulates the electrical power output from the generator or alternator and ensures that the battery is properly charged.

It is important to check the generator or alternator and the regulator regularly and replace any damaged or worn out components. A faulty generator or alternator or regulator can cause electrical problems and battery damage.

FAQ:

  1. How do I know if my motorcycle’s generator or alternator is working properly?
  2. You can use a voltmeter to measure the voltage output of the generator or alternator. The voltage should be between 13.8 and 14.5 volts when the engine is running.

  3. How do I know if my motorcycle’s regulator is working properly?
  4. You can use a voltmeter to measure the voltage output of the regulator. The voltage should be between 13.2 and 14.8 volts when the engine is running.

Conclusion

The wiring diagram for a 1966 Harley Davidson motorcycle is an important tool for troubleshooting electrical problems and performing repairs and modifications. It is important to check the various components of the electrical system regularly and replace any damaged or worn out components. By following the guidelines outlined in this article and using the tables and frequently asked questions for reference, you can ensure that your motorcycle’s electrical system is in good working order.
