Charging System Diagnostics - John's Auto Care - Boulder

The most expensive repair is where a problem is mis-diagnosed and a perfectly good part is needlessly replaced. That’s why our shop utilizes cutting-edge diagnostic tools to pinpoint charging system issues and experienced technicians to provide their expert analysis and interpretation of those results. This process ensures the accurate identification of your charging system issue, saving you time, money and aggravation.

Our Charging System Diagnostic Service includes a thorough inspection of the battery, alternator, voltage regulator, and associated components. We go beyond the surface to detect hidden problems that could affect your vehicle's performance.

Transparent Communication: We believe in transparent communication and pricing. Once we’ve completed our diagnostic assessment, we'll provide you with a detailed digital report of our findings, explain any issues and recommend the necessary repair or replacement, along with complete, all-inclusive pricing.

Expert Alternator Replacement Service

Alternator Repair Replacement - John's Auto Care - Boulder

If you’re experiencing electrical issues like dimming or flickering lights, a warning light on your dash, sluggishness or a battery that keeps dying, it could be a sign that your alternator has reached the end of its life and needs replacing. This situation is commonly misdiagnosed as a bad battery, especially if it’s an old one, which is why we do a complete diagnostic check on your charging system before determining the problem.

If your alternator does need replacing, we will replace it with a high-quality component that meets or exceeds industry standards and back up the repair with our 3 yr/36,000 mile nationwide peace-of-mind warranty.
