Main Components in AE86 Wiring Diagram
Battery
The battery is the primary source of electrical power in the car, which provides energy to start the engine and power the various electrical components. The AE86 uses a 12-volt lead-acid battery with a capacity of 40Ah or 45Ah, depending on the model. The positive terminal of the battery is connected to the starter motor, while the negative terminal is connected to the chassis ground.
Alternator
The alternator is responsible for charging the battery and supplying electrical power to the car’s electrical system when the engine is running. The AE86 uses a 12-volt alternator with a capacity of 60A or 70A, depending on the model. The alternator is connected to the battery via the alternator charging wire and the battery positive terminal. The alternator is also connected to the engine ground and the alternator warning light in the dashboard.
Starter
The starter motor is responsible for cranking the engine and starting the car. The AE86 uses a 12-volt starter motor with a solenoid that engages the starter gear to the engine flywheel to start the engine. The starter motor is connected to the battery positive terminal via the starter motor wire, and to the engine ground via the starter motor body.
Ignition Switch
The ignition switch is the key-operated switch that activates the car’s electrical system and starts the engine. The AE86 uses a four-position ignition switch with positions for off, ACC (accessory), ON, and START. The ignition switch is connected to the battery and the starter motor via the ignition switch wire, and to the various electrical components such as the lights, wipers, and radio via the ignition switch accessory wire.
Fuses and Relays
The AE86 uses various fuses and relays to protect the electrical system from overload and short circuits, and to control the operation of various electrical components. The fuses are inserted in the fuse box located in the engine bay, while the relays are placed in the relay box located near the battery. The fuses and relays are labeled according to their amperage and function, such as the EFI fuse, headlight relay, and horn relay.
Conclusion
The AE86 wiring diagram is a crucial tool for any owner or mechanic who wants to maintain or modify the car’s electrical system. Understanding the various components and circuits in the car can help in troubleshooting, repairing, and upgrading the electrical system. We hope this article has provided you with a comprehensive guide to the AE86 wiring diagram, and answered some of your questions about this iconic sports car.
