Carburetor problems can be frustrating, especially those involving the choke. A properly functioning choke is crucial for cold starting, ensuring your engine runs smoothly until it reaches operating temperature. While many older vehicles rely on manual chokes, modern systems often incorporate electric chokes for convenience and improved performance. This guide provides a step-by-step process on how to wire an electric choke, complete with wiring diagrams and troubleshooting tips. Mastering electric choke wiring can save you time, money, and frustration.
Understanding Your Electric Choke System
Before diving into the wiring process, it’s crucial to understand how an electric choke operates. An electric choke uses a bimetallic spring or a thermal resistor that heats up as the engine warms. This heating action changes the position of the choke plate, gradually opening the airflow to the carburetor as the engine gets hotter. The electrical system controls the heating element, regulating the choke’s function. Different systems have slightly different components and wiring configurations, so consulting your vehicle’s service manual is crucial.
Identifying Components
Typically, your electric choke system will consist of:
- Choke Housing: This houses the choke plate and the heating element.
- Bimetallic Spring (or Thermal Resistor): This component reacts to heat, controlling the choke plate’s position.
- Wiring Harness: This connects the choke to the vehicle’s electrical system.
- Power Source: Usually a switched 12V source, often from the ignition system.
- Ground: A connection to the vehicle’s chassis for completing the electrical circuit.
Step-by-Step Guide to Electric Choke Wiring
The exact wiring process can vary slightly depending on the vehicle and the specific electric choke model. Consult your vehicle’s service manual for precise instructions and diagrams. However, these general steps apply to most electric choke installations:
-
Disconnect the Battery: This is crucial for safety. Always disconnect the negative terminal before working on any electrical system.
-
Locate the Wiring Harness: Identify the wires coming from the electric choke on your carburetor. This usually consists of two or three wires: power, ground, and sometimes a thermal switch wire.
-
Identify the Power Source: The electric choke needs a switched 12V power source, typically activated when the ignition is turned on. This is usually found near the ignition switch or on a fuse box. Refer to your vehicle’s wiring diagram to confirm this.
-
Connect the Wires: The power wire needs a connection to your 12V switched source. The ground wire connects to a clean, grounded surface on the vehicle’s chassis. A third wire (if present) will be connected to a thermal sensor or a different control circuit. Never connect the power wire directly to the battery!
-
Reconnect the Battery and Test: After connecting all the wires, carefully reconnect the negative battery terminal. Start the engine and observe the choke’s operation. It should fully engage upon initial start and gradually open as the engine warms up.

Troubleshooting Common Electric Choke Problems
Even with careful wiring, problems can arise. Here are some common issues and solutions:
Electric Choke Stays Engaged
- Check the power supply: Ensure the power wire is connected to a switched 12V source and not a constant power source.
- Inspect the bimetallic spring/thermal resistor: A faulty heating element might prevent the choke from opening. Replacement may be necessary.
- Verify the ground connection: A poor ground connection can prevent the electric choke from functioning correctly.
Electric Choke Doesn’t Engage
- Check the fuse: Check for a blown fuse in the related circuit.
- Inspect the wiring for breaks or loose connections: Ensure all wires are properly connected and not damaged.
- Test the power supply: Use a multimeter to check if power is reaching the choke.
Different Types of Electric Choke Systems
While the basic principle remains the same, several types of electric choke systems exist. One common system uses a bimetallic coil to regulate the choke plate; another uses a thermal resistor. Understanding the specifics of your system will help you trouble-shoot it effectively. It’s also important to be aware that some electric choke systems integrate with other engine control systems, requiring more sophisticated diagnostics.

Different vehicles and even different years of the same model can have variations in their electric choke wiring. Always consult your vehicle’s specific wiring diagram for accurate information. It’s often found in your owner’s manual or can be obtained from a reputable online parts supplier.
Choosing the Right Replacement Choke
If you need to replace your electric choke, ensure you purchase the correct part for your vehicle’s make, model, and year. Purchasing a wrong part can lead to complications. Reputable auto parts stores can help identify the right component based on your vehicle’s information.
