Commercial Truck Electrical Repair & Diagnostics in Los Angeles, CA

Modern commercial trucks depend on increasingly complex electrical and electronic systems. When a warning light appears, batteries repeatedly lose their charge, a truck will not start, or electrical equipment stops working, accurately diagnosing the cause is critical.


L.A. Fleet Care provides commercial truck electrical repair and diagnostic services for diesel trucks, fleet vehicles, tractors, trailers, and other commercial vehicles throughout the Los Angeles area.


Our goal is to identify the source of the problem rather than simply replacing parts without determining why the failure occurred.

Diesel Truck Computer Diagnostics

Commercial trucks use onboard computers and electronic control systems to monitor engine performance and many other vehicle functions.


When a warning light or operating problem occurs, diagnostic equipment can provide important information about the affected system.


However, a diagnostic trouble code does not always identify the exact failed component. Proper diagnosis may require additional testing of wiring, sensors, electrical circuits, batteries, charging systems, or mechanical components.

Commercial Truck Electrical Problems

Electrical problems can be particularly frustrating because symptoms may be intermittent.


Common issues may include:

  • Truck will not start
  • Batteries repeatedly going dead
  • Alternator or charging problems
  • Check engine lights
  • Warning lights
  • Wiring problems
  • Blown fuses
  • Lighting failures
  • Sensor problems
  • Starter issues
  • Trailer electrical problems
  • Lift gate electrical issues
  • Intermittent electrical failures

Proper electrical testing helps isolate the cause before repairs are performed.

Battery, Starter and Charging System Diagnostics

A commercial truck that will not start does not necessarily need a new battery.


The problem could involve the battery, alternator, starter, wiring, electrical connections, excessive electrical draw, or another component.


Testing the complete starting and charging system helps determine why the failure occurred and reduces unnecessary parts replacement.

Fleet Electrical Diagnostics

Electrical problems affecting fleet vehicles should be addressed early.


Intermittent starting problems, warning lights, lighting issues, and battery problems can eventually result in a vehicle being unavailable when it is needed.


L.A. Fleet Care can incorporate electrical system inspections and diagnostics into ongoing commercial fleet maintenance.
