Semi Truck Alternator Repair

Your alternator powers critical electrical systems, from cab lights to safety sensors. When it fails, your truck can quickly become unsafe. Thompson Truck Source offers complete semi truck alternator repair services, including testing, rebuilding, and replacing alternators to ensure steady, reliable power.

We understand the demands placed on heavy-duty trucks and use advanced diagnostics to address issues at the source, rather than just treating the symptoms. That means you can reduce recurring breakdowns and keep your fleet productive.

A faulty starter is one of the most frustrating issues for drivers. Our team provides efficient fixes and semi truck starter replacement when repairs aren’t enough. Whether you need a solenoid fix, wiring repair, or a full unit swap, we have the tools and expertise to handle the job.

We also offer commercial truck starter repair service for fleets of all sizes, making it easy for managers to keep trucks road-ready without long delays.

Signs Your Truck Needs Alternator Repairs

Knowing when to schedule semi truck alternator repair can prevent costly breakdowns. Here are common warning signs:

  • Dim or flickering lights: Headlights and interior lights may fade or change brightness as the alternator struggles.
  • Battery issues: A dead or constantly drained battery may indicate that the alternator isn’t charging correctly.
  • Electrical malfunctions: Power windows, dashboard displays, or in-cab electronics may operate inconsistently.
  • Warning light: Many trucks have a dashboard indicator, often shaped like a battery, that signals charging system trouble.
  • Unusual noises: Grinding or whining sounds near the engine could mean a failing alternator bearing.

If you notice any of these or other signs of trouble, it’s time to visit a truck alternator repair shop before the problem escalates.
