Auto Electrical Repair & Maintenance Services
Alternators
An alternator is a crucial automotive component responsible for converting mechanical energy into electric energy (alternating current). It plays a pivotal role in your vehicle's engine, and any malfunction can result in your car's breakdown. If you encounter issues with your car's alternator, it is imperative to seek expert assistance.
Batteries
The battery is the powerhouse that supplies electrical energy to vital automotive systems such as the ignition system, starter motor, and lights. If you find yourself needing a jump-start to kickstart your vehicle in the morning, it may be a sign that your battery is deteriorating.
Depending on the extent of damage, a failing battery can either be repaired or replaced. If you are experiencing battery-related issues, do not hesitate to contact us in Doraville, GA. We offer convenient battery testing and replacement services, designed to swiftly get you back on the road. From battery replacement and charging to installation, testing, and recycling, we cover it all.
Starters
The starter serves as the motor, whether electric, hydraulic, or pneumatic, responsible for initiating the operation of your internal combustion engine. Starters are vital components within your car's engine, and any malfunction can lead to your vehicle's failure to start.
In the event of starter problems, it is crucial to seek professional assistance. Our team of experts is well-equipped to handle all your starter-related needs efficiently, ensuring you can resume your journey promptly. Visit J & N Auto Service today for expert starter services.
Battery FAQs
What are mistakes made when jumping a car?
Mixing up negative and positive cables is the most common mistake. When you mix up the negative and positive cable it ruins your car's alternator. Just remember black to negative and red to positive. Other common mistakes are using cheap cables that don't conduct properly, letting the cables swing and become detached, touching the clips together, and ignoring cracks in your battery or dirty battery terminals.
What should I be careful of when changing a car battery?
It may sound obvious but be sure that you do not drop the battery. Be careful not to let the tools touch both the negative and positive terminals simultaneously, as it could create a spark, cause the battery to short out, or even damage the vehicle's electrical components.
Make sure to separate the cables to the side so that they don't touch the battery until it is in place. Attach the negative cable first and then the positive cable. If have any doubts while you are trying to change your battery you should always call in an expert.
Car Starting FAQs
How do I unlock my steering wheel?
Place your foot on the brake and turn the wheel in the direction in which it has a little range of motion. This should ease the tension in the steering column and allow you to turn the key. Turning the key unlocks the steering wheel. Do not try to unlock your steering wheel without a key or if the battery is dead. This should only be done by a professional auto repair technician.
What does a dead starter sound like?
Clicking noises upon turning the key are a classic sign of starter failure. However, this isn't the only clue. A dying starter might remain completely silent or offer subtle warnings through whirring or grinding sounds before finally giving up the ghost.

What Our Customers Are Saying
I have been a customer of Jimmy's for at least eight years and he's the best mechanic in Atlanta. He has saved me tons of money over the years. He's honest and the best thing about his work is that he will get it right, when nobody else will. The people who know Jimmy and his work, faithfully bring their cars to him. When the job or the repair is really important, I only trust Jimmy. Mechanics everywhere owe Jimmy their gratitude for he surely is in a league all of his own in terms of consistency, quality, integrity and execution- all traits that 98% percent of mechanics know nothing about. Jimmy gets FIVE STARS from me, and you can take that to the bank brother!
Excellent, honest, fairly priced, fast service! I recently moved to Georgia and was in need of new rear brakes on my Suzuki SX4. I found J & N Auto online and gave them a call. Even though there were other vehicles being serviced, my brakes were finished within a couple of hours! This is not one of those franchise repair shops, just a good honest mechanic/owner with a staff of professional mechanics in a shop. I would DEFINITELY RECOMMEND Jimmy and his staff to anyone and will continue to call upon them in the future.
I decided to write this review months after my visit and I just wanted to say it was a great experience. My car still runs smoothly and the service was fast. Highly recommended.
Jimmy, the owner/mechanic, was professional and gave me a great deal, in comparison to my own research of what repairs I needed. Great place, huge shop, name brand parts, good customer service and repaired my vehicle in a timely manner. I recommend his services.
