About This Service
Modern vehicles rely on complex electrical systems for everything from starting the engine to controlling safety features. At Sanchez Automotive, we diagnose electrical problems systematically — testing the alternator, starter, battery, wiring, and related components to find the actual cause of the problem rather than replacing parts based on guesswork.

Frequently Asked Questions
How do I know if my alternator is bad?
Signs of a failing alternator include a battery warning light, dim or flickering lights, a battery that keeps dying, or a whining noise from the engine. We test the alternator output to confirm whether it's the cause.
What's the difference between a battery and alternator problem?
A bad battery typically causes a slow crank or no-start after the vehicle has been sitting. A bad alternator causes the battery to drain while the vehicle is running. We test both to determine which is the actual cause.
Why does my car battery keep dying?
A battery that keeps dying can be caused by a bad battery, a failing alternator, or a parasitic drain — something drawing power when the vehicle is off. We diagnose which is the cause before recommending a repair.
Can you diagnose wiring problems?
Yes. Wiring problems can be complex to diagnose, but we have the tools and experience to trace electrical circuits and identify shorts, open circuits, and damaged wiring.
