How To Test A Car Starter？

A modern starter is an electromechanical device that initiates an internal combustion engine. Both mechanical and electrical failures can lead to its malfunction.

A car starter is a reliable and durable part that can operate for years without issues with proper maintenance and careful handling. In most cases, bad starter symptoms can be noticed early, enabling timely replacement before a complete breakdown occurs.

Checking the Pinion Gear

To determine if the starter is faulty and requires replacement, inspect the pinion gear. A properly functioning gear should rotate in only one direction.

Testing Steps:

1.Remove the Bendix from the starter.

2.Secure it in a vise.

3.Attempt to rotate it in both directions.

If the gear moves freely in both directions, the gear must be replaced. Rebuilding a starter is not difficult, and the main thing is to buy the required spare parts at an affordable price.

Testing the Electrical System

If the starter motor fails to engage, first conduct a thorough inspection of the electrical part of the EO system before initiating any repairs.

Key Checks:

• Connection Integrity: Verify all wiring connections are securely fastened and free from corrosion.

• Mounting Verification: Confirm proper starter mounting and alignment.

• Battery Health Assessment: Test battery charge by activating headlights - significant dimming within 10-15 seconds indicates potential battery weakness.

Bench Testing the Starter

For a thorough assessment, professional testing on a specialized bench is recommended. This method provides a complete evaluation of the starter’s condition.
