Auto Electrical System Repair

Vehicles today have complex electronic systems that all must work in perfect harmony to ensure that the car functions properly. However, the diagnostic professionals at Thurston County Transmission have been offering help with auto electrical in Lacey WA to drivers since 1989.

If one or more of these systems has a problem, it throws the whole vehicle out of whack pretty quickly. Our crew has the experience necessary to get to the root of your electrical auto problems. There are four general areas of issues that drivers face:

Alternator and charging systems

When owners start having problems with the alternator or charging system of their vehicles, the first sign of trouble is often a dimming of the headlights. Other times the problem manifests itself with the engine failing to crank or being slow to crank. The charging system is responsible for keeping the car battery charged and it supplies voltage for the entire electrical system.

A faulty alternator, voltage regulator or wiring can cause real problems for a vehicle. A slipping or broken drive belt can also cause charging problems. Once the charging system fails, the battery will discharge quickly and the car will shut down soon after because none of its on-board electronics will get enough power. Our team of diagnostic pros hold years of experience in dealing with alternator and charging systems and can help get your vehicle powered up and back in action.


Battery problems are usually quite easy to diagnose. A quick test of a car battery by a diagnostic expert can tell whether the battery has reached the end of the road and needs to be replaced. Our experts understand which battery brands to trust, and can simplify installation for customers.

Electrical diagnosis and repair

In general it is best to get your vehicle’s electrical system completely checked out and tested once every two years. Sometimes drivers will notice driving problems that can be directly linked with electrical issues such as voltage variations.

Electric problems directly affect how functional a car is on the road, due to the fact that most modern cars use computerized control systems. Even minor spikes in voltage can cause major problems with these controls. Thurston County Transmission has the diagnostic tools to get to the root of any problem and can also perform routine maintenance checks.

Computer scanning and flashing

The process of scanning or flashing a car computer is complex. This may coax some additional performance out of your vehicle, however. Professionals may be able to help you scan or flash the computer in your vehicle if electronic errors keep coming up and no obvious fixes are resolving the issue.
