Our Electrical Diagnostic Process

We follow a structured method to isolate the fault precisely.

1

Initial Consultation

You describe the symptoms – dim lights, dead battery, etc.

2

Visual Inspection

Check battery terminals, fuses, and wiring for corrosion or damage.

3

Battery/Charging Test

We test the battery and alternator output using professional equipment.

4

Parasitic Draw Test

We measure current draw with all modules asleep to find the leak.

5

Circuit Ground Test

We verify voltage drops on power and ground circuits.

6

Module Communication Check

Use the factory scan tool to see if all ECUs are online.

Electrical Diagnostics Questions

Quick answers to your electrical worries.

Usually a parasitic drain from a module, interior light, or faulty alternator diode.

We use current probes and thermal cameras to isolate shorts within an hour.

Yes, but a proper diagnosis ensures the alternator is actually charging and no drains persist.

CAN bus testing starts at $129, and if a module is dead we'll quote replacement separately.
