Starters are components that are responsible for getting engines to turn over so that they can receive air and burn fuel. When this commercial truck part doesn’t work, you won’t be going anywhere. But since starters work together with the battery, alternator, and ignition switch, it isn’t always easy to tell if this commercial truck part is to blame for your engine problems. If you’re having trouble firing up your semi, here are a few signs that you need a new starter.

5 Signs of Bad Starters in Commercial Trucks

1. Slow Start or No Start

If the engine doesn’t start and jumping or replacing the battery doesn’t help, the starter may be the culprit. If the engine starts but takes longer than usual to turn over, it’s possible that the starter is not receiving enough voltage. Since slow-starting will only cause more mechanical damage over time, have the commercial truck part inspected, and if necessary, repaired or replaced.

2. Dim Dash Lights

Failing starters can sometimes get the engine to power up, but will need to draw extra voltage to work correctly. As a result, you may notice that the dash lights dim anytime you turn the ignition.

3. Unusual Noises  

Hearing any assortment of odd sounds upon ignition could indicate a starter problem. Clicking, for instance, suggests that the component isn’t receiving enough electrical power. Grinding, on the other hand, can mean that the starter drive gear is worn out. A whining sound is a sign that the starter gear is not engaging with the flywheel.  

4. Oil Leak

An oil leak can do more than leave your engine without essential lubrication — it can also soak the starter to the point where it will no longer work correctly. If you spot an oil leak, have it repaired as soon as possible and make sure the starter is still in working shape.

5. Smoking

Smoke coming from under the hood can sometimes mean that the starter is getting too much power, has shorted, or is outfitted with a bad connection. Whatever the cause, don’t operate your vehicle until it has been inspected and serviced.
