Transport Diesel knows heavy duty electrical systems.

The electrical system is primarily composed of the starter motor, battery and alternator. These three parts are responsible for starting the engine, keeping it running and powering all electrical components like the radio, lighting, windows, locks, windshield wipers, air conditioning and more.

Over time, factors like vehicle age, mileage and daily driving conditions can affect your electrical system and keep it from starting or operating normally.

A malfunctioning electrical system in a heavy duty truck can present several signs and symptoms that should not be ignored. Some of the most common signs include

1. Dimming or flickering lights
2. Slow engine cranking or starting problems
3. Warning lights or error codes on the dashboard
4. A dead battery or alternator
5. Blowing fuses or tripped circuit breakers
6. Inaccurate readings from gauges and sensors
7. Electrical equipment failures such as power windows, air conditioning, or radio
8. Sagging or overloading of the battery or alternator, electrical arcing or burning odors
9. Unusual noises or vibrations coming from the electrical system.

If you notice any of these symptoms, you should have your truck’s electrical system inspected by Transport Diesel’s professional technicians as soon as possible to avoid further damage or potential safety hazards.
