Circuit and draw testing
Parasitic draw testing, ground checks and wiring repairs track down the faults that come and go.

Auto Electrical Repair questions
Do I need a battery or an alternator?
Testing tells us in a few minutes. A weak battery and a failing alternator feel similar from the driver's seat but cost very different amounts.
Can you find an intermittent electrical problem?
Usually yes. It takes real diagnostic time, and we quote that time up front so there are no surprises.
Do you repair wiring instead of replacing the harness?
Where it is safe and reliable, we repair the damaged section rather than sell you an entire harness.
