What we service
Electrical services at All About Automotive
Battery testing and replacement
Load testing on every battery check — not just a surface voltage reading. We test cold cranking amps against the battery's rated spec and replace it if the capacity has dropped to a point where cold-weather starting becomes unreliable.
Alternator service
Charging system output test, voltage regulator check, and alternator replacement. A failing alternator will drain your battery and strand you without warning. We catch it early with a systematic charging system test.
Starter motor repair
If you hear a click or nothing when you turn the key, the starter motor or its relay may be at fault. We test the full starting circuit — battery, cables, relay, and starter — before replacing any component.
Electrical diagnostics
Wiring faults, blown fuses, bad grounds, and failed modules. Electrical problems require a systematic diagnostic process. We use wiring diagrams and circuit testing tools to trace faults to their source.
Lighting and fuses
Headlights, taillights, brake lights, interior lighting, and fuse box diagnosis. We check for circuit problems behind a failed light before replacing bulbs so the same fuse does not blow again.
Sensor and module diagnosis
Oxygen sensors, MAF sensors, crankshaft position sensors, and other electronic components that trigger warning lights or affect driveability. We confirm the sensor is the fault — not the wiring — before replacing it.
Why it matters
Modern vehicles run on electricity
Every system in a modern vehicle — engine management, transmission shifting, ABS, stability control, and climate control — depends on electrical sensors, modules, and wiring. An electrical fault does not always produce an obvious symptom right away. It can appear as an intermittent warning light, a sensor code that clears itself, or an accessory that sometimes works and sometimes does not.
Those intermittent symptoms are worth diagnosing while they are intermittent, not after they become a hard failure. Electrical diagnosis is the one area of auto repair where the cost of a correct diagnosis up front is almost always less than the cost of misdiagnosis and unnecessary parts replacement.
Common questions
Battery and electrical FAQ
How long do car batteries last?
Most car batteries last three to five years under normal driving conditions. In the Pacific Northwest, battery life is often shorter than the national average because of the combination of cold starts in winter and heat soak in summer. If your battery is more than three years old, we recommend having it load-tested — not just checked for charge — at your next oil change. A load test tells you how much capacity the battery has left under real starting conditions, not just whether it holds a surface charge.
What causes a car not to start?
A no-start has three common causes: a dead or weak battery, a failed starter motor, or a failed alternator that did not charge the battery on the last drive. Less common but possible: a bad ignition switch, a faulty neutral safety switch (automatic transmissions), a blown fuse, or a security system lockout. We start with a battery and charging system test before pulling anything apart. That narrows it down quickly and avoids misdiagnosis.
How do I know if my alternator is failing?
Common symptoms include a battery warning light on the dash, dimming headlights especially at idle, electrical accessories behaving erratically, and a battery that keeps going dead even after being replaced. The alternator charges your battery while the engine runs — if it stops doing that, the battery drains and eventually the car stops. An alternator that is failing but not dead yet may charge inconsistently, which is why symptoms can seem intermittent before the car simply will not start.
Can you diagnose electrical gremlins — lights, sensors, accessories not working?
Yes. Modern vehicle electrical systems are complex, and most electrical problems require scan tools, wiring diagrams, and a methodical diagnostic process to trace correctly. We do not guess at electrical problems. We perform circuit tests, check fuses and relays, pull codes where applicable, and trace the fault to the actual component or wiring section before recommending a repair. Electrical problems that are misdiagnosed the first time become expensive.
