Alternator or battery? The symptoms overlap
A failing alternator and a dying battery produce confusingly similar symptoms — which is why the parts-store parking-lot guess so often replaces the wrong one. Rough guide: battery problems show up when starting; alternator problems show up while driving (dimming lights, battery warning light, electrical weirdness, then a car that dies mid-trip and won't restart). We test both plus the connections between them before quoting anything.
Why these repairs are perfect for mobile
A car with a dead alternator or starter can't drive to the shop — that's the whole problem. The traditional path is a $100-150 tow plus shop diagnostics before repair pricing even starts. The mobile path: we come to the car, confirm the diagnosis, and replace the unit right there. One trip, one bill, no tow.
Frequently asked questions
How long does an alternator replacement take on-site?
Most vehicles: 1-2 hours once we're there. Some engine layouts bury the alternator and take longer — your quote reflects your actual vehicle, not a fantasy average.
Is a remanufactured alternator okay?
Often yes — quality remans carry solid warranties and save real money. We'll quote new and reman where both make sense and let you choose.
