A short to power in a vehicle wiring loom forces the user to disable the ignition circuit to turn off park lights, and there is no efficient way to locate the short without tearing through the entire wiring harness.

Workarounds Described

• pulls every fuse and connector in the cabin
• uses multimeter to check resistance on park light circuit
• pulls 30A ignition fuse to turn off park lights
• considers tearing through the whole wiring loom

Implied Software Gaps

• Non-invasive signal tracing tool that pinpoints short-to-power locations within sealed wiring looms without unwrapping

ShortSniffer Probe

ShortSniffer Probe is a handheld device that injects a low-current, modulated signal into a wire circuit and uses a directional probe to trace the exact point of a short to power or ground through insulation and tape. No need to cut or unwrap wiring looms — the probe audibly and visually signals the path and the fault location.
