Frequently Asked Questions

How do I know my alternator is failing?

Look for battery warning light on dashboard, whining or grinding noise from engine, burning smell, dimming lights, or difficulty starting. We confirm with diode and load tests.

Can I drive with a failing alternator?

Not recommended. A failing alternator won't charge your battery, and you may get stranded. If the battery light is on, get it checked immediately. We offer same-day diagnostic service.

How long does alternator replacement take?

Most alternator replacements take 1-2 hours depending on your vehicle model. Diagnostic testing takes 30-60 minutes. We can usually complete the job same-day.

New vs reconditioned alternator - which is better?

New alternators offer longer lifespan and better warranty. Reconditioned alternators are cost-effective for older vehicles. We offer both options with warranty and help you choose based on your vehicle's age and budget.
