Alternator Repair

Your vehicle's alternator must be in good repair. The alternator provides electrical power while the engine is running. It also recharges the battery that brings your engine to life. Without an alternator the battery will quickly drain leaving you and your wheels dead in the water.

Alternator Symptoms

alternator repairTelltale signs of alternator repair issues include dash lights that flash momentarily; dimmed or dimming headlights; and flickering gauges. There may even be an odd smell (of burning rubber or hot wires) and/or a growling sound beneath your hood.

Most 21st century vehicle dashboards have instruments clusters that carry warning lights, one of which is an ALT light (short for alternator). At the outset of alternator problems, the ALT light may flicker or light up only when accessories are used.

Do you ask your vehicle to multitask—to run headlights, wiper blades, the radio, heated seats and the like all at once? Your alternator must work harder to supply you with the electricity you need to do all that. When your alternator isn’t working properly, or you’re asking too much of it, it may signal your vehicle to put on the warning light. Dim and extremely-bright headlights frequently indicate an alternator that is going south on you. Accessories that begin to misbehave are another stark symptom that all is not well with your alternator.

I had to bring my car back in due to more electrical problems, the diagnostic fee was waived since I had just been in two weeks ago for similar issues. Solved the problem with a new alternator and that was it! Very fair of the folks to do that. I'll be coming back again.
