Modern cars are rolling computers. When something electrical goes sideways — a battery that won't hold a charge, a starter that hesitates, a check engine light you can't ignore — diagnosis matters as much as repair. At Complete Brake Service, auto electrical is part of the comprehensive automotive care we've offered since 1986. We isolate the actual cause, then fix exactly what's wrong — not a parts-cannon guess.
From a dead battery in your driveway to an intermittent gremlin no one else can find, we handle the full range of common electrical issues on cars and light trucks.
Battery testing and replacement, alternator diagnosis, charging system inspection, and the math to tell you if a battery, alternator, or parasitic drain is the real cause.
Starter motor testing and replacement, ignition switch issues, no-crank and slow-crank diagnostics. Fixing the cause, not just throwing parts at the symptom.
Check engine light scans, computer module diagnostics, sensor testing, wiring and circuit tracing. The hard-to-find intermittent stuff lives here.
Headlights, brake lights, turn signals, dash lights, power windows and locks, fuses and relays. The everyday electrical fixes that make a car feel right again.

Electrical issues rarely fix themselves. Catching them early often turns a $50 fix into a $50 fix — versus a tow and a much bigger bill.
Real diagnostics, fair pricing, and the experience to spot the root cause behind the symptom.

Since 1986, we've worked through every kind of electrical gremlin from carbureted classics to today's CAN-bus computers. Pattern recognition matters.
Brakes are the namesake, but we also handle oil changes, tires, alignments, suspension, and electrical for light vehicles. One trusted shop for everything your car needs.
Diagnostic findings come with a written quote. You decide what gets done, with full understanding of what's needed and what isn't.
The questions Columbus drivers ask us most about electrical issues.
Common signs include slow cranking when starting, dimming headlights at idle, the battery warning light, frequent need for jump-starts, or a battery that's more than 4-5 years old. The most accurate answer comes from a load test, which measures whether the battery actually holds the cranking amperage your engine needs. We do load testing as part of our standard electrical workup.
The starter motor uses battery power to crank the engine. Once running, the alternator generates electricity to power everything and recharge the battery. If the car won't crank at all, it's usually the battery, starter, or a connection. If the car runs but the battery keeps dying or the lights dim at idle, the alternator is the more likely culprit. Diagnosing which is which takes about 15 minutes with the right equipment.
Three common causes: the battery itself is failing, the alternator isn't charging properly, or there's a parasitic drain — something staying powered when it shouldn't (a stuck relay, an interior light, an aftermarket accessory). A good electrical diagnostic isolates which one. Just replacing the battery without finding a parasitic drain means you'll be doing it again in a few weeks.
Typical car batteries last 4 to 6 years, depending on climate, driving habits, and battery quality. Short trips and extreme heat shorten battery life; long highway drives and moderate temperatures extend it. If yours is past 4 years and showing any starting symptoms, get it tested before it leaves you stranded.
The check engine light is the engine computer telling you it detected something outside expected parameters — anything from a loose gas cap to a failing oxygen sensor to a serious misfire. The only way to know is to scan the stored fault codes. A solid (non-flashing) light usually isn't an emergency, but it should be checked soon. A flashing light means stop driving — it usually indicates a misfire that can damage the catalytic converter.
Yes — and it's some of the work we take the most pride in. Intermittent electrical issues (a no-start that starts the next day, a window that works most of the time, a dash light that comes and goes) are notoriously hard to find but almost always have a logical cause. We use systematic testing, scope and meter readings, and pattern recognition to track them down.
Yes. We replace bulbs, clean and reseal foggy headlight assemblies, fix wiring issues to lighting circuits, and replace failed LED units in newer vehicles. Lighting failures are also a common ticket item at traffic stops, so it's worth fixing promptly.
