Why Is My Truck Having Electrical Problems?

Electrical issues in heavy-duty trucks can result from factors such as aged components, loose connections, corrosion, or short circuits. A precise diagnosis by a professional technician is essential to pinpointing and resolving the underlying causes of these problems.

What Happens When an Alternator Fails?

When the alternator fails in a heavy-duty truck, the battery's charge depletes rapidly, leading to electrical system malfunctions and potential engine stalling. It's crucial to address alternator issues promptly to avoid breakdowns and potential damage to other electrical components.
