The vehicle has a battery-drain or intermittent wake-up complaint. A fuse is removed for testing, then refitted, and the problem disappears. That is useful history, but it does not prove the fuse was the fault or the vehicle is repaired.
In a Pico technical-forum discussion, Steve Smith explains that removing and reinserting a fuse can alter a connection or reset the protected controller. The post examines using voltage drop across a known fuse resistance to estimate current, while discussing limitations such as temperature, measurement noise and current-clamp drift.

Preserve the state you are trying to understand
For a garage referral, record what woke the vehicle, how long it had been left and what changed immediately before the symptom disappeared. Include whether doors, keys, diagnostic equipment or a charger were involved. Keep the original measurements alongside any later readings.
An advanced measurement is only helpful if its resolution and assumptions suit the question. Do not apply a resistance value from an unrelated fuse or treat a tiny noisy signal as a precise current figure. This is a diagnostic planning point, not a universal current limit for a sleeping vehicle.
What an owner can contribute
Write down how long the car stands before the problem occurs and whether it started after an accessory or electrical repair. Keep recovery and battery-test reports. Avoid repeatedly disconnecting the battery before the workshop can capture the fault, unless the vehicle’s safety instructions require it.
This discussion concerns professional low-voltage diagnosis. Do not probe traction-battery circuits or remove high-voltage components. Send AXION the fault history to discuss the appropriate assessment route, including whether the complete vehicle is needed.
