Common Electrical System Problems and Symptoms

Dead Battery

A dead battery is a common electrical system issue in heavy-duty trucks. This can be caused by a faulty alternator, parasitic drain, or an old battery that needs to be replaced.

Ignition System Failure

Ignition system failure can be caused by a faulty starter, a damaged ignition switch, or a dead battery. This can lead to a truck that won't start or stall during operation.

Dimming or Flickering Headlights

Dimming or flickering headlights can be caused by issues with the alternator or a loose or corroded electrical connection.

Electrical System Warning Lights

Warning lights such as the check engine light, battery light, or charging system light can indicate issues with the electrical system. These lights should be addressed immediately to avoid further damage to the truck's electrical system.

Malfunctioning Alternator

A malfunctioning alternator can lead to a dead battery, dimming or flickering headlights, and other electrical system issues. A professional diagnostic and electrical repair service can quickly diagnose and repair alternator issues.

What Our Customers Are Saying About Us

Mike Murphy

Absolutely the best….Real Mechanics…quality work…friendly staff…and Fair Prices…

Alan Lopez

Family owned where you feel like part of it. King pin, front axel leaf spring and all brakes replacement performed plus alignment( about 3 blocks straight when tested, didn't try more for safety reasons) . No issues at all. Easy access shop for small trucks and trailers surrounded by a huge yard where parking spots available for rent. King pins removed with the proper press no hammer, no heat. Third party financing available. I strongly recommend this business.

Orlando San Jorge

Excellent shop, every work done here is +5 stars, but alignment is from other world, if you make your alignment here, you really get what you are trying to get, maybe the only place in USA where this job is really well done! Nice people, friendly, they took a little longer than other shops, but is just a value added to get the quality they offer in their works. If I have to say it in numbers, I should say: 99.9% of the times you don't have to came back to the shop for the same issue. Nice work guys, keep it that way!

Let me tell you if you want your truck fixed fast take it here. I had my truck at a shop for 4 months couldn’t fix it. Decided to bring it here and they fixed it in 4 day like are you serious. Best part was that they charge me about the same price the other shop tried to charge me for doing nothing.
