Why accurate diagnosis matters
Electrical symptoms rarely point to one obvious part. A dead battery could be the battery, alternator, or a parasitic draw. Proper testing prevents replacing good parts.
Electrical questions & answers
Why does my battery keep dying?
A recurring dead battery can be a failing battery, a weak alternator, or a parasitic draw. We test each to find the actual cause.
Can you fix power window and lock problems?
We diagnose and repair many common electrical accessory issues. We'll let you know if a concern is outside our scope.
Do electrical problems trigger warning lights?
Often, yes. We read the codes and test the related circuits to find the root cause rather than assuming from the code alone.
