How to Fix a Bad Starter on a Car

Introduction

A car’s starter is an essential component that ignites the engine. If the starter malfunctions, the car won’t start. In this article, we’ll show you how to fix a bad starter on a car.

Step 1: Identify the Problem

The first step in fixing a bad starter is to identify the problem. If you turn the key, and nothing happens, it could be a bad starter. However, if you hear a clicking sound, it could be a weak battery or a loose connection.

Step 2: Check the Battery

If you suspect a weak battery, you can use a voltmeter to check its voltage. A fully charged battery should read around 12.6 volts. If it’s below 12 volts, it might be time to replace the battery.

Step 3: Check the Connections

If the battery is okay, check the connections between the battery and the starter. Loose or corroded connections can prevent the starter from working correctly. Clean the connections and tighten them if necessary.

Step 4: Check the Solenoid

If the battery and connections are okay, the problem could be the solenoid. The solenoid is a small component that connects the battery to the starter. You can check the solenoid by using a multimeter to measure its resistance. If it’s out of range, you might need to replace the solenoid.

Step 5: Check the Starter Motor

If the solenoid is okay, the problem could be the starter motor itself. You can check the starter motor by using a jumper cable to connect the positive terminal of the battery to the positive terminal of the starter motor. If the starter motor turns, it’s working correctly.

Step 6: Remove the Starter

If the starter motor doesn’t turn, it’s time to remove the starter from the car. You can do this by disconnecting the battery and removing the bolts that hold the starter in place.

Step 7: Disassemble the Starter

Once you’ve removed the starter, you can disassemble it to check for any damage. Look for worn brushes, a damaged armature, or a broken solenoid.

Step 8: Replace the Faulty Parts

If you find any damaged parts, you can replace them with new ones. You can buy replacement parts from a local auto parts store or online.

Step 9: Reassemble the Starter

Once you’ve replaced any faulty parts, reassemble the starter and reinstall it in the car. Make sure all the connections are tight and secure.

Step 10: Test the Starter

Finally, test the starter to make sure it’s working correctly. Reconnect the battery and turn the key. If the engine starts, you’ve successfully fixed the bad starter.
