The first step when wiring up a Delco Chevy 4 Wire Alternator is to identify the two main types of terminals. The first is the positive terminal and the second is the negative terminal. The positive terminal is usually labeled “B” and the negative terminal is labeled “G”.

The next step is to identify the wires that connect these two terminals. The positive wire is usually labeled “R” and the negative wire is labeled “Y”. The positive wire should be connected to the positive terminal and the negative wire should be connected to the negative terminal.

After the wires are connected, it’s time to connect the alternator to the battery. To do this, you’ll need to find the battery terminal and connect the positive wire to it. The negative wire should be connected to the negative terminal on the battery. Make sure the connections are tight and secure.

Once the connections are made, you’ll need to identify the ground wire. This is usually labeled “G” and should be connected to a good ground. This is important because it ensures the alternator is properly grounded.

Now that you’ve identified all of the wires and connected them correctly, it’s time to connect the alternator to the vehicle’s fuse box. To do this, you’ll need to identify the alternator’s fuse box terminal. This is usually labeled “F” and should be connected to the main power supply in the vehicle.

The last step is to connect the alternator to the vehicle’s starter. To do this, you’ll need to identify the starter’s terminal. This is usually labeled “S” and should be connected to the starter. Make sure the connections are tight and secure.

Now that you’ve connected the Delco Chevy 4 Wire Alternator correctly, you’ll need to verify the connections. To do this, you’ll need to use a voltmeter. Connect the positive lead of the voltmeter to the positive terminal on the alternator and the negative lead to the negative terminal on the alternator.

If the reading is higher than this, it may indicate a problem and should be checked out by a professional mechanic.

Once you’ve verified the connections, you’re ready to start the engine and test the alternator. Turn the key in the ignition and start the engine. After a few minutes, check the voltmeter again and make sure the reading is still between 13.5 and 14.5 volts. If the reading is lower than this, it may indicate a problem and you should contact a professional mechanic to diagnose and repair the issue.
