"Battery not charging" light when the battery + alternator are fine

テキスト:

My 2004 GMC Yukon shows “Battery not charging” rather frequently on the dash but by all measures, the battery and alternator are fine.

* I’ve got a steady 14.6v every place I can measure when the car is running
* 12.6v when it’s not
* I’ve checked AC ripple with the car on and see none.
* The battery voltage gauge on the dash shows the same things I measure (12.5v when off, 14.5 when running)
* The light is obviously wrong, but its weird that the system which is telling me its not charging (via the light and message) is also telling me that it’s fine (via the gauge).

Anyone know how it could be thinking the battery isn’t charging even though it is?
