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.

I took my 93 Nissan to Dennis Hall back in March because it was idling rough and had them go ahead and do a rear end service on it as well. They did great work and at an adorable price. It is now August and I noticed it looked like my rear end had leaked a little bit and called them to see if I need to schedule an appointment to get it looked at again. They told me to just stop by and they would check it out free of charge to make sure everything still seemed correct. They got me in and out quickly and very pleased they took the time to make sure their work was correct and didn't make me have to pay for another service. I will be going back for all my vehicle needs 10/10 auto shop!

Had an issue pop up when we were traveling on the interstate. We stopped here and they helped us out super quick and were very nice. If I lived in town this would be my mechanic.
