We service your auto battery and electrics issues

At Jake's Auto Garage in Harper we understand that the charging and electrical systems are the most intricate and complex systems on your vehicle, particularly modern cars. Our highly trained technicians have access to the proper equipment to diagnose and repair any electrical issues that your car may be faced with. We have the mechanics and the tools to get the job done right the first time!

At one time, batteries were primarily used for starting the vehicle. However, these days batteries do a lot more than that. A bad cell or weak battery can cause many kinds of electronic malfunctions for a vehicle. Alternators no longer simply spin and generate power either. Typically, information is fed through the ECU and an array of sensors communicate with the alternator, telling it to switch on and off and how much power to provide.

The bottom line is, in a world of ever-increasing complexity concerning your vehicle’s electrical systems, our expert mechanics are now a necessity rather than a convenience. We can test, isolate, and repair any issue, big or small; from oil changes to complex wiring issues, your car is in good hands here at Jake's Auto Garage in Harper.
