Frequently Asked Questions
What are the signs of a failing alternator?
Dashboard warning light (battery symbol), dim headlights, electrical issues (windows moving slowly), whining noise from the engine bay, and a dead battery despite being recently replaced are all common signs.
Can a bad alternator damage my battery?
Yes. A failing alternator can undercharge or overcharge the battery, both of which shorten battery life significantly. If your alternator fails, have the battery tested before fitting a replacement.
