Auto Electrical Repair FAQs
Why does my car keep dying even with a new battery?
A new battery that keeps dying usually points to a bad alternator, a parasitic drain from a faulty component, or corroded cables and connections. We'll run a full charging-system and parasitic-draw test to pinpoint the cause.
How long does an electrical diagnosis take?
Most electrical diagnostics are completed within 1–2 hours. Complex intermittent issues may take longer, but we'll always walk you through what we find before doing any repair work.
Can you fix wiring problems on older cars?
Yes. With 30+ years of experience, we work on everything from classic vehicles with traditional wiring to modern cars with CAN bus and multiplexed systems.
My check engine light is on — is that electrical?
It can be. The check engine light is triggered by the engine computer, and many causes are electrical — sensors, wiring, grounds, or the computer itself. We'll scan for codes and trace the real source.
