12 volt warning in cold while plugged in

[TaxmanHog]

Assuming the 23B70 TSB for the LVB Sensor fixes this charging issue, is there a test I should ask the dealer to do to prove that the LVB is fully functional and not in need of replacement as well?

One of the members who is a Ford tech mentioned a load test that takes a few hours to complete, not the 3 minute version you get from autozone.
