Maintenance logs say work was done. This page says whether it worked: each recorded job is checked against the connector's readings afterwards.
A job “held” when readings returned to the connector's normal range and stayed there for at least 3 readings over 14 days. Jobs still being confirmed are not counted in the rate.
| Work | Recorded | Held | Relapsed | Partial / none | Confirming | Held rate |
|---|---|---|---|---|---|---|
| Contacts cleaned | 2 | 1 | 1median 32 days | 0 | 0 | 50% of 2 |
| Connector or cable replaced | 1 | 1 | 0 | 0 | 0 | 100% of 1 |
Small numbers: a rate from a handful of jobs is an early signal, not a verdict on a method or a technician.
Readings fell from 0.294 mΩ before the work to 0.312 mΩ and stayed within the normal range (≤ 0.32 mΩ) for 4 readings over 27 days.
Readings fell from 0.277 mΩ before the work to 0.218 mΩ and stayed within the normal range (≤ 0.242 mΩ) for 8 readings over 53 days.
Readings fell from 0.318 mΩ before the work to 0.25 mΩ, within the normal range (≤ 0.274 mΩ), but rose above it again 32 days later (0.288 mΩ on 19 Sept 2026). The underlying cause may not have been removed.
