The wiring diagram is useful when troubleshooting electrical problems in your car. It allows you to trace the circuit and locate the problem easily. This ensures that the repairs are done correctly, and the car runs smoothly.
The wiring diagram is divided into sections, which include the engine compartment, interior, and rear lights. Each section contains information about the electrical connections for each component.
In the engine compartment, you will find information about the starter, alternator, and ignition system. In the interior section, you will find information about the lights, radio, and power windows. In the rear lights section, you will find information about the tail lights and brake lights.
The wiring diagram also includes a legend that explains the various symbols used in the diagram. Understanding these symbols is crucial in interpreting the diagram correctly.
The Legend
The legend is a key that explains the symbols used in the wiring diagram. It is essential to understand the symbols to interpret the diagram correctly. Here are some of the symbols used in the 91 CRX wiring diagram:
| Symbol | Description |
|---|---|
| B | Battery positive |
| G | Ground |
| L | Light |
| S | Sensor |
Understanding the symbols will make it easier for you to follow the wiring diagram and locate any problems in your car’s electrical system.
Wiring Diagram for Engine Compartment
The engine compartment is the heart of your car’s electrical system. It contains the starter, alternator, and ignition system. Here is a detailed wiring diagram for the engine compartment:
Starter Circuit
The starter circuit in your CRX is responsible for cranking the engine. Here is how the circuit works:
The battery positive connects to the starter solenoid through a fuse. When you turn the key in the ignition, a signal is sent to the starter solenoid, which engages the starter motor. The starter motor then cranks the engine.
The starter circuit is a relatively simple circuit that can be easily diagnosed if it fails. Here is the wiring diagram for the starter circuit:
Alternator Circuit
The alternator is responsible for charging the battery and supplying power to the car’s electrical system. Here is how the alternator circuit works:
The battery positive connects to the alternator through a 100-amp fuse. The alternator produces AC current that is then converted to DC current by the rectifier. The DC current is then sent to the battery and the car’s electrical system.
If the alternator fails, the battery will not be charged, and the car’s electrical system may fail. Here is the wiring diagram for the alternator circuit:
Ignition Circuit
The ignition circuit is responsible for starting the engine and providing power to the spark plugs. Here is how the ignition circuit works:
When you turn the key in the ignition, a signal is sent to the ignition switch. The ignition switch then sends a signal to the starter solenoid and the ignition control module. The ignition control module sends a signal to the spark plugs, which ignites the fuel in the engine.
If the ignition circuit fails, the engine will not start. Here is the wiring diagram for the ignition circuit:
Wiring Diagram for the Interior
The interior of your car includes the lights, radio, and power windows. Here is a detailed wiring diagram for the interior of your car:
Lights Circuit
The lights circuit is responsible for powering the lights in your car. Here is how the circuit works:
The battery positive connects to the headlight switch. When you turn the switch to the on position, a signal is sent to the interior light relay, which then powers the lights.
If the lights circuit fails, the lights in your car will not work. Here is the wiring diagram for the lights circuit:
Radio Circuit
The radio circuit is responsible for powering the radio in your car. Here is how the circuit works:
The battery positive connects to the radio through a fuse. The radio is then powered on through the ignition circuit.
If the radio circuit fails, the radio in your car will not work. Here is the wiring diagram for the radio circuit:
Power Windows Circuit
The power windows circuit is responsible for powering the power windows in your car. Here is how the circuit works:
The battery positive connects to the power window switch through a fuse. When you press the switch to the up or down position, a signal is sent to the power window relay, which then powers the window motor.
If the power windows circuit fails, the power windows in your car will not work. Here is the wiring diagram for the power windows circuit:
Wiring Diagram for Rear Lights
The rear lights include the tail lights and brake lights. Here is a detailed wiring diagram for the rear lights of your car:
Tail Lights Circuit
The tail lights circuit is responsible for powering the tail lights in your car. Here is how the circuit works:
The battery positive connects to the tail light relay through a fuse. When you turn the headlights on, a signal is sent to the tail light relay, which then powers the tail lights.
If the tail lights circuit fails, the tail lights in your car will not work. Here is the wiring diagram for the tail lights circuit:
Brake Lights Circuit
The brake lights circuit is responsible for powering the brake lights in your car. Here is how the circuit works:
The battery positive connects to the brake light switch through a fuse. When you press the brake pedal, a signal is sent to the brake light switch, which then powers the brake lights.
If the brake lights circuit fails, the brake lights in your car will not work. Here is the wiring diagram for the brake lights circuit:
