Frequetly Asked Question
Why does my battery keep dying even after I replace it?
A new battery won’t fix underlying charging or drain issues. We’ll test your alternator, check for parasitic drains, and inspect key electrical circuits to pinpoint the problem.
What’s a parasitic draw and how do you fix it?
It's when an electrical component continues drawing power even when your car is off. We use multimeter testing and circuit tracing to identify the faulty part and fix or replace it.
My dashboard lights flicker or don’t come on — why?
It could be a grounding issue, a failing alternator, or faulty wiring. We test your voltage flow, control circuits, and wiring integrity to fix it right.
Can you program key fobs and ECUs?
Yes. We have the tools to reprogram or replace most keys, fobs, and electronic control units — including immobilizer and security systems.
Yes, we work on both traditional and high-voltage systems. Let us know your vehicle type when booking, and we’ll match you with a qualified technician.
