1. Battery:
- The positive terminal of the battery is connected to the ignition switch.
2. Ignition Switch:
- The ignition switch has several terminals, including:
- BAT: Connected to the positive battery terminal.
- IGN: Connected to the ignition coil.
- ACC: Connected to the accessory circuit.
- START: Connected to the starter solenoid.
3. Ignition Coil:
- The ignition coil has two terminals:
- +: Connected to the positive terminal of the ignition switch.
- -: Connected to the distributor.
4. Distributor:
- The distributor has several terminals, including:
- +: Connected to the ignition coil.
- -: Connected to the ground.
- Terminals for each spark plug.
5. Spark Plugs:
- Each spark plug has a terminal that connects to the distributor.
6. Ground:
- The negative terminal of the battery is connected to the vehicle's chassis, which acts as the ground.
7. Starter Solenoid:
- The starter solenoid is connected to the ignition switch and the starter motor.
8. Accessory Circuit:
- The accessory circuit includes various electrical components such as the radio, lights, and wipers. It is powered by the ignition switch.
9. Resistor (Optional):
- Some ignition systems include a resistor wire or ballast resistor to limit the flow of current to the ignition coil.
It's important to note that this is a simplified diagram, and the actual wiring may vary based on the vehicle and the type of ignition system used. Always refer to the specific vehicle's wiring diagram for accurate information.
