Helpful answers
Electrical Diagnosis
questions.
Why does my new battery keep dying?+
The charging system may be weak, the vehicle may have an excessive key-off draw, or a connection may be poor. The battery itself is only one part of the system.
Can you find an intermittent electrical problem?+
Often, yes, though intermittent faults can take time. Details about weather, temperature and when the symptom occurs help us reproduce it.
Do you repair damaged wiring?+
We diagnose wiring faults and can repair many damaged wires, terminals, grounds and connectors when the location and condition make a durable repair possible.
