A Zero-Ohm Resistor Can Become Intermittent When Its Termination Breaks
A zero-ohm resistor reportedly measured an unstable 4-30 ohms while installed, but measured near its nominal low resistance after removal.

What the evidence preview establishes
One termination had lost a substantial portion of its metallization and nickel barrier. The report considered this damage the most likely explanation for the intermittent resistance while the resistor was mounted; it found no broader as-fabricated construction defect.
Why this case matters
When a zero-ohm component measures high or unstable resistance in circuit, inspect both metallized ends and section the suspect termination. Interpret post-removal resistance in light of changed contact geometry and probe resistance.
