What Is The Best Test To Check A Starter?


A starter is one of the key components in a vehicle’s electrical system, responsible for turning over the engine and allowing it to start. Over time, starters can wear out or develop faults, resulting in difficulties in starting the engine. To determine if the starter is the issue, there are several tests that can be performed. In this article, we will explore the best tests to check a starter.

1. Visual Inspection

The first step in checking a starter is to perform a visual inspection. This involves examining the starter for any signs of damage, such as corrosion, loose connections, or frayed wires. If any issues are detected, they should be addressed before proceeding with further tests.

2. Battery Voltage Test

The next test involves checking the battery voltage. A weak or dead battery can often mimic symptoms of a faulty starter. To perform this test, follow these steps:

  1. Connect a voltmeter to the battery terminals.
  2. Turn off all electrical loads, including lights, radio, and accessories.
  3. With the voltmeter connected, attempt to start the engine.
  4. Observe the voltmeter reading. It should remain above 9.6 volts during cranking.

If the voltage drops below 9.6 volts or if the battery is weak, the problem may lie with the battery rather than the starter.

3. Solenoid Click Test

The solenoid click test can help determine if the starter solenoid is functioning correctly. Follow these steps:

  1. Locate the starter solenoid, typically mounted on or near the starter motor.
  2. With the ignition key in the “ON” position, use a jumper wire to bridge the connection between the battery positive terminal and the solenoid terminal.
  3. If you hear a distinct click sound, it indicates that the solenoid is functioning properly. If not, the solenoid may be faulty.

4. Voltage Drop Test

The voltage drop test helps determine if there are any voltage losses between the battery and the starter motor. Follow these steps:

  1. Connect a voltmeter between the positive terminal of the battery and the positive terminal of the starter motor.
  2. Attempt to start the engine while monitoring the voltmeter reading.
  3. A reading of less than 0.5 volts indicates a good connection. Anything higher may signify a voltage drop issue.
  4. Repeat the test between the negative terminals of the battery and the starter motor.

If excessive voltage drops are detected, there may be a problem with the starter cables or connections that require attention.

5. Starter Drive Gear Test

The starter drive gear is responsible for engaging and disengaging the flywheel teeth. A faulty drive gear can prevent the starter from operating correctly. Follow these steps to perform the test:

  1. Disable the ignition system to prevent the engine from starting.
  2. Locate the starter drive gear on the starter motor.
  3. Manually rotate the drive gear in both directions.
  4. If the gear does not engage or disengage smoothly or makes strange noises, it may be faulty.


Performing the tests mentioned above can help diagnose starter-related issues in a vehicle. It is essential to follow these steps carefully and observe any signs of abnormalities. In some cases, professional assistance may be required to accurately diagnose and resolve starter problems. Regular maintenance and inspection of the starter can also help prolong its lifespan and prevent unexpected failures.
