Electrical Faults
1. Question the driver - Symptom ≠ Fault — Interrogate the Interface!
2. Stop and think - Pause Before Probes!
3. Eliminate broad faults - Resistance Rules the Realm!
4. Scan systems - Code Sweep: Go Wide, Not Just Deep!
5. Wiring diagram - Blueprint Before Breakpoint!
6. Commonality check - Shared Path or Solo Act?
7. Pull-up/pull-down logic - Voltage Bias: Up or Downstream?
8. Access points first - Touch What’s Tappable!
9. Tool efficiency - Data Density Over Drama!
10. Non-intrusive testing - Probe Without Poke!
