Your battery gets the engine started, but it’s your alternator that powers everything else — every mile you drive. A failing charging system can leave you stranded without much warning, which is why Franklin Automotive takes electrical diagnostics seriously. Our experienced technicians are well-versed in the complex charging systems found in today’s vehicles, from feature-loaded SUVs like the Toyota 4Runner and Jeep Grand Cherokee to everyday commuters like the Nissan Altima and Honda CR-V. If your dashboard warning light is on, your headlights are dimming, or your battery keeps dying, don’t wait — bring it in and we’ll get to the bottom of it.
Call (615) 472-8052 Schedule your charging system test at 307 5th Ave N, Franklin, TN 37064 — we'll make sure your vehicle's electrical system is running exactly as it should.

Signs Your Alternator is Failing
A struggling alternator rarely goes completely silent before it gives out. Because it’s responsible for keeping your headlights on, your ignition running, and every electronic system in your vehicle powered, the warning signs tend to show up in multiple places at once. Look out for:
- Headlights that flicker or appear dimmer than usual, especially at idle
- A grinding or whining noise from the engine bay that changes with engine speed
- The battery or ALT warning light illuminating on your instrument cluster
Slower-than-usual power windows, a radio that cuts in and out, or a battery that won’t hold a charge overnight are also common signs that your alternator is no longer keeping up with your vehicle’s electrical demands.
Professional Charging System Testing
At Franklin Automotive, we don’t replace parts on a hunch. Before any repair is recommended, we conduct a full charging system evaluation to rule out simpler causes — like a worn serpentine belt, a corroded terminal, or a battery that’s simply reached the end of its life.
Our diagnostic process covers:
- Measuring alternator output voltage under a real-world electrical load
- Checking for parasitic draws that could be silently draining your battery
- Inspecting the serpentine belt for wear, cracking, or slippage
Getting the diagnosis right the first time means you’re not paying for parts you don’t need — and you’re leaving our shop with a fully healthy electrical system.
