Battery Questions and Answers

Q: What are mistakes made when jumping a car?

A: 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.

Q: What should I be careful of when changing a car battery?

A: 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.

Q: How do I replace my car battery without losing car memory?

A: Use a car memory saver or other secondary power source. If you don't own a car memory saver, come to Barnes Auto Service and we can do this process for you. First, make sure to turn off your car before you unplug the battery. Next, plug the car memory saver into the cigarette lighter or the OBD2 connector. Remove the old battery and install the new battery and attach the connectors. Finally, unplug the memory saver from the car.

Q: Do I need to reprogram my car after battery replacement?

A: Your cars' complex electrical and computer systems rely on the battery. However, for a gas-powered car it is unlikely that you will need to reprogram or reset the electrical system or computer system after replacement. When you get your battery replaced at an auto repair shop, they may use a secondary power source when changing your battery to ensure that your electrical system and vital computer systems do not lose power. Reprogramming or resetting the electrical and computer systems only needs to be done if your car battery has been dead or disconnected for a long period of time. During a reset your car computers will return to the original manufacturing setting and lose any data it has collected such as information for oxygen to gas ratios during shifting.

Q: Why is my engine stalling after replacing my car battery?

A: If your car lost battery power completely then your car's computer system may have lost valuable information to regulate engine performance causing it to stall even after you replace the battery. However, the car's system will quickly collect new data and engine performance should return to normal. In some case you may need to have the throttle body, or your idle air control valve cleaned out as carbon deposits can build up inside these parts, pushing them beyond the computer's ability to regulate engine performance.

Car Starting Questions and Answers

Q: How do I unlock my steering wheel?

A: 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.

Lights Questions and Answers

Q: What are the 3 situations where headlights are required?

A: First, you should make sure both of your headlights are in good working order before driving your car. Headlights must be in use from sunset to sunrise. Headlights are also necessary when you cannot see more than 400 feet in front of you. You should also use your car's headlights whenever windshield wipers are in use. In addition, some studies have shown that when drivers elect to always drive with their headlights on it can reduce automobile accidents.

Q: Do parking lights and turn signals use the same bulb?

A: Yes, your car uses the same bulb for the front turn signal and parking lights. Side bulbs are located on the inside of the wheel wells. All lights on your car will eventually burn out and need to be replaced.
