Service Description

<h2>Battery, Starter &amp; Alternator Service</h2> <p>Few things are more frustrating than turning the key and getting nothing. Whether your vehicle will not start, cranks slowly, or the battery keeps dying, MZ Auto Repair in Fort Washington, MD can quickly determine whether the problem is your battery, starter, alternator, or something else entirely.</p> <h2>Common Symptoms</h2> <ul> <li>Vehicle will not start or cranks slowly</li> <li>Clicking noise when you turn the key but the engine does not start</li> <li>Battery keeps dying or needs frequent jump-starts</li> <li>Dimming headlights or interior lights, especially at idle</li> <li>Battery warning light on the dashboard</li> <li>Electrical accessories behaving erratically</li> <li>Grinding or whining noise when starting</li> </ul> <h2>How We Diagnose the Problem</h2> <p>A no-start condition can be caused by a weak battery, a failing starter motor, a bad alternator, corroded connections, or even a parasitic drain that kills the battery overnight.

Extreme heat, like Maryland summers, tends to shorten battery life.</p> <h3>How can I tell if it is the battery or the alternator?</h3> <p>If the car starts with a jump but the battery dies again quickly, the alternator may not be charging. If the battery is simply old and cannot hold a charge, it needs replacing. We test both to determine the actual cause.</p> <h3>Do you offer a warranty on batteries?</h3> <p>Yes, the batteries we install come with a 24-month/24,000-mile warranty.</p> <h3>What is a parasitic drain?</h3> <p>A parasitic drain is an electrical component that continues drawing power when the vehicle is off, slowly killing the battery. Common causes include faulty door switches, aftermarket accessories, or a malfunctioning module. We perform targeted testing to find and fix the source.</p>
