Mostly you will need to remove any covers or shields covering the alternator to access the voltage regulator. Make sure to take note of the wiring connections and how they are connected to the regulator before proceeding.
Step 3: Connect the Voltmeter
Connect the voltmeter to the battery and take note of the reading. A fully charged battery should have around 12.6 volts. While the engine is on, check the voltmeter reading again. If it reads below 13 volts, it indicates an issue with the alternator. This is where full fielding comes in handy as it can help diagnose the problem further. If the voltmeter reading is above 13 volts, then the problem may lie elsewhere.
Step 4: Bypass the Voltage Regulator
To fully field an alternator, you need to bypass the voltage regulator. To do this, connect a jumper wire from the positive terminal of the battery to the field terminal on the back of the alternator. This will send maximum voltage directly to the rotor winding, bypassing the regulator. Make sure the jumper wire is connected securely and use caution while working around the battery.
Step 5: Recheck the Voltage
With the engine running, recheck the voltmeter reading. If it has increased significantly, it means that there was an issue with the voltage regulator and it needs to be replaced.
If the voltmeter reading remains low, then the problem lies with the alternator itself, and it may need to be repaired or replaced. If there is no change in the voltmeter reading, then the issue may lie with the wiring between the alternator and battery.
Step 6: Disconnect Jumper Wire
Once you have completed full fielding and made your diagnosis, disconnect the jumper wire from the positive terminal of the battery and the field terminal on the back of the alternator. Make sure to reconnect any wiring and covers removed during the process.
While full fielding can help diagnose issues with an alternator, it should not be used as a long-term solution. It is recommended to get any necessary repairs or replacements done promptly.
Step 7: Reconnect Battery Terminal
Finally, reconnect the negative terminal of the battery and start your vehicle to ensure everything is working correctly. If you have followed all the steps correctly, your alternator should now be fully functional, providing enough power for all your vehicle’s electrical components.
