If you’re looking for a reliable and efficient carburetor for your vehicle, the Edelbrock 1406 is a great option to consider. This carburetor features an electric choke system that ensures the engine starts easily and runs smoothly in any weather condition. However, if you’re not familiar with the wiring diagram of the Edelbrock 1406 electric choke, you may find the installation process more challenging than necessary.
This journal article is designed to walk you through the process of wiring the Edelbrock 1406 electric choke as easily and effectively as possible. Here’s what you need to know:
What is an electric choke?
An electric choke is an automatic device that regulates the air/fuel mixture in a carburetor when starting a cold engine. It works by restricting the flow of air to the carburetor, thus creating a richer fuel mixture that’s necessary for a cold engine to start smoothly. Once the engine warms up, the electric choke opens up, allowing normal air intake and fuel flow. Compared to manual chokes that require driver intervention, electric chokes are more convenient and reliable.
How to wire the Edelbrock 1406 electric choke?
The wiring diagram of the Edelbrock 1406 electric choke is relatively simple and easy to follow. Here are the steps you need to take:
Step 1 – Disconnect the battery:
Before you start wiring the electric choke, make sure the battery is disconnected to avoid any electrical shocks or accidents. You can disconnect the negative terminal of the battery using a wrench or socket.
Step 2 – Locate the positive terminal of the ignition coil:
The positive terminal of the ignition coil is a crucial connection point for the electric choke. You can find it on the coil itself or on the distributor cap. The positive terminal is usually marked with a (+) sign.
Step 3 – Connect the electric choke power wire:
Take the electric choke power wire and connect it to the positive terminal of the ignition coil using a piggyback connector or a spade terminal. Make sure the connection is tight and secure to avoid any power loss or short circuiting. You can use a voltage meter or a test light to check if the power is flowing correctly.
Step 4 – Connect the ground wire:
The electric choke ground wire is another essential connection that ensures proper functioning of the choke. You can connect the ground wire to any clean and unpainted metal surface on the engine block or chassis. Make sure the connection is tight and secure to avoid any grounding issues or electrical interference.
Step 5 – Test the electric choke:
Once you’ve made all the necessary connections, you can test the electric choke by turning on the ignition switch and observing the choke plate’s movement. The choke plate should be closed when the engine is cold and gradually open up as the engine warms up. If the choke plate doesn’t move or moves too slowly, you may need to adjust the connections or consult a professional mechanic.
FAQ
Q: Why does my engine stall after starting with the electric choke?
A: If your engine stalls after starting with the electric choke, it may be due to a rich fuel mixture that’s flooding the engine. This can happen if the electric choke is misadjusted or if the carburetor is clogged or malfunctioning. You may need to clean or rebuild the carburetor or adjust the choke settings to solve the problem.
Q: How do I adjust the electric choke on my Edelbrock 1406 carburetor?
A: To adjust the electric choke on your Edelbrock 1406 carburetor, you need to follow these steps:
- Warm up the engine to operating temperature
- Disconnect the electric choke wire from the positive terminal of the ignition coil
- Remove the air cleaner to access the choke housing
- Adjust the choke housing index tab to the desired position using pliers or a screwdriver
- Reconnect the electric choke wire and test the choke plate’s movement
Q: Can I install an electric choke on my old carburetor?
A: Yes, you can install an electric choke on your old carburetor, provided that the carburetor has a choke housing or a choke plate. You may need to buy an electric choke conversion kit that includes the necessary wiring, hardware, and instructions. Installing an electric choke can improve your engine’s cold-start performance and fuel efficiency.
