Electrical problems traced to the source.

Today's cars run on dozens of computers talking over a network of wires. When something electrical goes wrong, guessing gets expensive fast. Our technicians use wiring diagrams, scan tools and meters to find the actual fault.


What we diagnose and repair
  • Batteries that keep going dead and parasitic drains
  • Alternators and starters
  • Lights, power windows, door locks and mirrors
  • Blown fuses and shorted or corroded wiring
  • Warning lights and module communication faults
  • Backup cameras, sensors and accessories


Hybrids and electric vehicles add high-voltage systems on top of the usual 12V wiring. We are a Slate Automotive authorized repair partner and service hybrids and EVs every day, so we know how the two systems interact and how to work on them safely.

Frequently asked questions

  • How do I know if it's my battery or my alternator?

    If the car will not start but runs fine after a jump, the battery is the likely cause. If it dies while driving or the lights dim as you drive, suspect the alternator. We test both to be sure.

  • What is a parasitic drain?

    It is something that keeps drawing power after the car is off, like a stuck relay, a glovebox light or an aftermarket accessory. It slowly drains the battery overnight. We track it down circuit by circuit.

  • Why are electrical problems hard to find?

    Many are intermittent and depend on heat, moisture or vibration. The more you can tell us about when it happens, the faster we can reproduce it and find the cause.

A+ has been my auto repair shop for the last 5 years. They have an outstanding crew that are always very professional and thorough in assessing the car, identifying issues, and fixing them right the first time. If you have japanese car this is the #1 shop.

This is my first time going to A+ Japanese Auto Repair and I plan to return for other car repair/maintenance services. I appreciate the total transparency and honesty. The complementary ride to and from the shop is extremely helpful. As a bonus they have loyal rewards program and all work is backed by a warranty which they explain what it is. The staff is friendly and answer questions that you have.

Took my 19 year old Tacoma to A+ Japanese Auto based on the reviews. I knew it needed a 150K service, and they suggested an inspection along with an oil change so they could determine what services were needed. The front office staff was exceptional from the time I made my appointment, arrived to the shop, and discussed the recommended repairs. The technicians took detailed photos shown me by my service provider. She explained all of the details regarding the repairs necessay and helped categorize the repairs based on safety. I was very impressed with this level of service, and highly recommend this business.

The founder of A+ came to the United States from Turkey and started out as a bicycle mechanic, then spent years as a head technician at a dealership. In 1997, in his mid-40s, he opened A+ Japanese Auto Repair in San Carlos. It was a family affair from the first day.
