Breakdown of Components
The 1969 Honda 90 wiring diagram includes several main components, each with its own unique symbol and function. These components include:
| Component | Symbol | Function |
|---|---|---|
| Battery | B | Stores electrical energy |
| Ignition switch | SW1 | Controls power to the ignition system |
| Rectifier | REC | Converts AC to DC current to charge the battery |
| Condenser | C | Stores electrical energy and helps regulate voltage |
| Coil | CI | Generates high voltage for the spark plugs |
| Spark plug | SP | Ignites the fuel-air mixture in the cylinder |
These components are connected by wires of various colors, which are also represented on the wiring diagram. Understanding these connections is essential for proper maintenance and operation of your motorcycle.
Battery
The battery is the heart of the electrical system and provides power to all the components. It is represented by the letter B on the diagram and is typically located under the seat. The positive terminal is connected to the ignition switch, while the negative terminal is grounded to the frame. It is important to keep the battery charged and maintained to ensure proper function.
Ignition switch
The ignition switch controls power to the ignition system and is represented by the symbol SW1. It is typically located on the handlebars and has three positions: Off, On, and Start. The switch is connected to the battery and the ignition coil, allowing for a spark to be generated when the engine is turned over.
Rectifier
The rectifier converts AC current from the alternator to DC current to charge the battery. It is represented by the symbol REC and is typically located under the seat. The rectifier has four connections: AC input, DC output, ground, and battery positive. It is important to ensure that these connections are secure and functioning properly.
Condenser
The condenser helps regulate voltage in the electrical system and is represented by the symbol C. It is typically located near the coil and has two connections: one to ground and one to the points on the ignition system. The condenser stores electrical energy and releases it when needed, helping to regulate voltage and protect the system from damage.
Coil
The coil is the component responsible for generating high voltage for the spark plugs. It is represented by the symbol CI and is typically located near the engine. The coil has two connections: one to the condenser and one to the spark plug. It is essential to ensure proper connections and function of the coil to maintain proper ignition and performance.
Spark plug
The spark plug is the final component in the ignition system and is responsible for igniting the fuel-air mixture in the cylinder. It is represented by the symbol SP and is connected to the coil. It is important to ensure that the spark plug is functioning properly and replaced when necessary.
