When your car’s alternator fails, it can be a frustrating experience. A broken alternator can cause your car’s battery to die, leaving you stranded on the side of the road. However, fixing a broken alternator is not as difficult as you might think. In this article, we will walk you through the steps to fix a broken alternator and get your car back on the road.
Step 1: Diagnose the Problem
The first step in fixing a broken alternator is to diagnose the problem. The most common symptoms of a broken alternator include a dead battery, dimming headlights, and a warning light on your dashboard. If you notice any of these symptoms, it’s time to check your alternator.
Start by inspecting the alternator belt. If the belt is loose or broken, it could be the cause of your problem. Tighten or replace the belt if necessary. If the belt is in good condition, you will need to test the alternator.
Step 2: Test the Alternator
To test the alternator, you will need a voltmeter. Start by disconnecting the negative battery cable. Then, connect the voltmeter to the battery terminals. Start the engine and rev it up to 2000 RPM. The voltmeter should read between 13.5 and 14.5 volts. If the reading is below this range, the alternator is not charging the battery and needs to be replaced.
Step 3: Remove the Alternator
If you have determined that the alternator needs to be replaced, it’s time to remove it from your car. Start by disconnecting the negative battery cable. Then, disconnect the wiring harness and remove the alternator belt. Finally, remove the bolts that hold the alternator in place and remove the alternator from your car.
Step 4: Replace the Alternator
Once you have removed the broken alternator, it’s time to replace it with a new one. Install the new alternator in the reverse order of removal. Remember to tighten the alternator belt to the proper tension and reconnect the wiring harness.
Step 5: Test the New Alternator
After you have installed the new alternator, it’s time to test it. Use your voltmeter to check the voltage at the battery terminals with the engine running. It should read between 13.5 and 14.5 volts. If the reading is lower, you may have a problem with the new alternator.
Step 6: Reconnect the Battery
Once you have tested the new alternator, reconnect the negative battery cable. Start the engine and check for any warning lights on your dashboard. If everything is working properly, you’re good to go.
Conclusion
Fixing a broken alternator is not as difficult as you might think. By following these simple steps, you can replace a broken alternator and get your car back on the road. Remember to always be safe when working on your car and consult a professional if you are unsure about any of the steps.
