A healthy alternator should output around 13.5 to 14.5 volts.
“A common misconception is that a new battery guarantees a trouble-free electrical system,” says automotive electrical expert, David Miller. “A failing alternator can quickly drain even a brand new battery.”
Common Causes of Battery and Alternator Problems
Understanding the underlying causes can help prevent future issues. Batteries can fail due to age, extreme temperatures, or excessive drain from leaving lights on. Alternators can fail due to worn-out brushes, a faulty voltage regulator, or damaged diodes.
Simple Solutions and Preventative Measures
Regular maintenance, like cleaning battery terminals and checking the alternator belt, can extend the life of these components. Ensuring your battery is properly secured can also prevent damage from vibrations. “Regularly inspecting your car’s electrical system is like getting a checkup for your car’s heart,” adds Miller. “It can catch potential problems early and save you from costly repairs down the road.”
Remote Diagnostics and Software Solutions
