Failure #3: Intermittent Fault Flag (Pin 4 toggles randomly)

• Diagnosis: Monitor across the shunt resistor (R25) with an oscilloscope.
• Root Cause: The 2021 layout places R25 too close to a switching MOSFET (Q2). Electrical noise triggers the LM339 comparator.
• Fix: Replace R25 with a 0.01Ω 1% metal film resistor and reroute the sense traces (per the schematic layout notes).
