The Ignition System
The ignition system is responsible for igniting the fuel mixture in the engine. This system comprises several components, such as the ignition coil, spark plug, and pulse generator. The ignition coil transforms the low voltage battery power to high voltage that ignites the fuel mixture in the engine cylinder. The spark plug is responsible for creating a spark that ignites the fuel mixture in the engine cylinder. Finally, the pulse generator is responsible for measuring the engine speed and sending this information to the electronic control unit (ECU).
The Charging System
The charging system is responsible for charging the motorcycle's battery while the engine is running. This system comprises several components, such as the alternator and regulator/rectifier. The alternator generates electricity using the engine's rotational power. The regulator/rectifier controls the amount of current flowing through the system and converts AC power to DC power.
The Lighting System
The lighting system is responsible for providing illumination for the motorcycle. This system comprises several components, such as the headlight, taillight, turn signals, and dash lights. The headlight provides illumination for the rider while riding in low-light conditions. The taillight provides illumination for the motorcycle's rear end and increases visibility for other drivers on the road. The turn signals provide an indication of the motorcycle's direction while turning, while the dash lights provide illumination for the motorcycle's instrumentation panel.
The Horn System
The horn system is responsible for alerting other drivers of the motorcycle's presence on the road. This system comprises a single component, the horn itself, and a relay that connects the horn to the battery and the switch. When the switch is activated, the relay sends power to the horn, which creates a loud sound.
The Neutral Indicator and Starter System
The neutral indicator and starter system are responsible for indicating the motorcycle's neutral position and starting the engine. The neutral indicator signals whether the bike is in neutral or a gear. The starter system comprises several components, such as the starter motor and starter solenoid. The starter motor uses battery power to turn the engine over and the solenoid is responsible for engaging the motor to the engine.
The Turn Signal System
The turn signal system is responsible for indicating the motorcycle's direction when turning. This system comprises several components, such as the turn signal switch, flasher relay, and bulbs. The turn signal switch is located on the handlebars and is used to activate the turn signals. The flasher relay is responsible for controlling the rate at which the turn signals flash. The bulbs provide illumination for the turn signals.
The Brake System
The brake system is responsible for stopping the motorcycle. This system comprises several components, such as the front and rear brake switches and the brake light. When the brake levers are activated, the switches send power to the brake light, which indicates to other drivers that the motorcycle is stopping.
The Fan System
The fan system is responsible for cooling the motorcycle's engine. This system comprises a fan and a thermal switch. When the engine temperature rises, the thermal switch sends power to the fan, which turns on and begins cooling the engine.
The Reverse System
The reverse system is responsible for allowing the motorcycle to move backward. This system comprises a reverse motor and reverse relay. When activated, the reverse relay sends power to the reverse motor, which turns the rear wheel in the opposite direction, allowing the motorcycle to move backward.
Modifications to the Wiring Diagram
There are several modifications that can be made to the wiring diagram to improve the performance of the motorcycle. For example, modifying the charging system to include a higher output alternator can improve battery charging and maintain a stable voltage. Adding an additional fuse box can also help to protect electrical components from voltage spikes. Finally, installing LED bulbs for the lighting system can reduce power consumption and increase visibility.
The wiring diagram of the 1984 Honda Goldwing GL1200 is a complex system that can be overwhelming to novice and experienced mechanics alike. However, by understanding the various components and their functions, it is possible to diagnose and repair any electrical problems that may arise. Additionally, simple modifications can improve the performance of the motorcycle and increase its longevity. By taking the time to study the wiring diagram, motorcycle enthusiasts can improve their understanding of this classic touring motorcycle and keep it running smoothly for years to come.
