FAQs

What Areas Do You Serve?

We are based at 2050 SW Deerhound Ave. Suite 103 and 102, Redmond, OR 97756, near S Hwy 97. In addition to Redmond, OR, we proudly serve customers throughout Oregon, Washington, Idaho, and Nevada within a 150-mile radius, with extended service available across Oregon when needed.

Can A Bad Alternator Ruin Your Battery?

Yes. A failing alternator can undercharge or overcharge the battery, both of which can shorten battery life and create additional electrical problems. Common warning signs include dim lighting, charging system warnings, hard starting, or repeated dead battery issues.

What Is The Difference Between A Code Reader And A Diagnostic Tool?

A basic code reader retrieves stored fault codes, while a professional diagnostic tool provides detailed system data, live sensor readings, troubleshooting information, and advanced testing capabilities. Diagnostic tools allow technicians to accurately identify electrical, engine, and performance-related issues within modern trucks.
