When it comes to wiring a 350 Chevy distributor, it’s important to understand the basics of how it works. The distributor is responsible for transmitting high voltage from the ignition coil to the spark plugs at the correct time. If the wiring is not done correctly, the engine may not start or run poorly. In this article, we’ll provide a step-by-step guide on how to wire a 350 Chevy distributor.
Step 1: Disconnect Battery
The first step in wiring a 350 Chevy distributor is to disconnect the battery to prevent any accidents. This will ensure that there is no power running through the system while you work on it. You can do this by disconnecting the negative battery cable from the battery terminal.
Step 2: Remove Old Distributor Cap
Next, remove the old distributor cap carefully to access the wiring. Make sure not to damage the cap or any other parts while removing it. You can remove the cap by unscrewing the retaining screws or clips holding it in place.
Step 3: Locate Wiring Diagram
Before wiring the new distributor, it’s important to locate a wiring diagram specific to your vehicle. This can usually be found in the owner’s manual or online. It’s important to use the correct diagram to ensure that the wiring is done correctly.
Step 4: Install New Distributor Cap
After locating the correct wiring diagram, install the new distributor cap onto the distributor shaft. Make sure that the cap is securely in place and that the spark plug wires are aligned with the correct terminals on the cap.
Step 5: Connect Wiring
Now it’s time to connect the wiring to the distributor. Using the wiring diagram as a guide, connect the positive wire from the ignition switch to the positive side of the coil. Then, connect the negative wire from the distributor to the negative side of the coil. Finally, connect the spark plug wires to the correct terminals on the distributor cap.
Step 6: Test Engine
After wiring the new distributor, it’s important to test the engine to ensure that everything is working correctly. Reconnect the battery and start the engine. If the engine starts easily and runs smoothly, then the wiring was done correctly. If there are any issues, refer back to the wiring diagram and double-check the connections.
