Mobile Alternator Diagnostic & Replacement Medford, OR

Starting at $299 (includes diagnostic)

If Your Battery Keeps Dying, It Might Not Be the Battery

The battery starts your car. The alternator keeps it running and recharges the battery while you drive. When the alternator starts failing, it stops doing its job. The battery drains. The car dies. You replace the battery. It drains again. Sound familiar?

Alternator failures are regularly misdiagnosed because the symptoms look like a battery problem right up until the point they don't. Dim headlights while driving, electrical accessories that behave strangely, a battery light that comes on and off, these are alternator symptoms, not battery symptoms.

We test the charging system before we pull anything apart. If the alternator is putting out proper voltage and amperage, we're not going to recommend replacing it. We trace the actual problem, could be a loose belt, a bad ground, a failing voltage regulator, and tell you exactly what needs to happen.

Frequently Asked Questions

Q: How do I tell if it's my alternator or my battery? A: Jump-start the car and disconnect the jumper cables. If the car dies quickly after running on its own, the alternator isn't charging — that's the alternator. A bad battery typically doesn't cause the car to die once it's already running.

Q: How long does alternator replacement take? A: Depends on the vehicle. Some are straightforward 1 to 1.5 hour jobs. Others have the alternator in tight locations that require more disassembly. We give you an honest time estimate before we start.

Q: Do you warranty the alternator? A: Yes. We use quality replacement parts and our work is warranted. Warranty details are confirmed at the time of service.

Q: Can you come if I'm stuck at home in Central Point? A: Absolutely. Central Point is right in our service area. Book online or call and we'll get to you.
