Electrical problems are where parts-cannon repairs get expensive. A battery that dies overnight, a fuse that keeps blowing, a window that works on Tuesdays — these need a wiring diagram, a meter, and patience. We find the actual fault, whether it's a chewed harness, a corroded ground, or a module that's staying awake.
Signs you need electrical diagnostics & repair
- Battery dies when the car sits
- Fuses blow repeatedly
- Intermittent electrical gremlins
- Multiple warning lights at once
- Dash flickers or gauges drop out
What we do on site
- Pull codes from every module, not just the engine
- Perform a parasitic draw test if the battery is draining
- Trace the circuit with a wiring diagram and meter
- Inspect grounds, connectors, and harness routing for damage
- Repair wiring properly with soldered or crimped-and-sealed connections
Doing this in a driveway
Diagnostics are easier at your home, honestly — the car is in the environment where the problem happens and we can leave a draw test running overnight.
Parts we use
Wiring, connectors, fuses, relays, grounds, or the failed component once identified.
Pricing: Hourly diagnostic, quoted up front, with the repair estimated once we know the cause. Every job is quoted in writing before we start, and there's no upsell — how our pricing works.
FAQ
Electrical Diagnostics & Repair: common questions
Why does my battery die overnight?
Something is staying on. Common culprits are aftermarket stereos, glovebox or trunk lights, a stuck relay, or a module that won't sleep. A parasitic draw test pinpoints the circuit.
Do you fix rodent-damaged wiring?
Yes, and we see it constantly in rural Iredell and Alexander County. Mice love soy-based wire insulation. We repair the harness and can add deterrent tape.
