Vehicles today have miles of wiring.  Most of what used to be just mechanical is now computer driven.  When a vehicle has an electrical problem it can affect anything from your wipers and your radio to your transmission not functioning or your engine not starting.  Our full electrical diagnosis starts with a scan of your vehicle's on board computer. We then check grounds. We check to make sure it's charging properly. We check for corrosion and check for damaged or cut wires. From there we trace wires using an electrical schematic for your vehicle.
