When coming to a stop door locks reset and check charging system comes on

[FranklinB]

I own a 2014 Edge limited.

 I replaced the alternator and have had the battery and charging system checked.

When slowing the door locks reset, the charging system alert comes on as well as the dash dims. It also occurs when I begin to move after the stop.

At night the headlights dim and then come back to full power.

Last night on the freeway all the lights came on suddenly then emitted a bright flash and back to normal. 

Any suggestions would be greatly appreciated.

so did this problem exist before you did the alternator replacement?

I'll presume so, so you need to figure out where the loose connection is. 

whether at the battery itself or the far ends of the primary power cables, there is almost certainly a loose connection. 

The tests of your battery and charging system are irrelevant because they are not being performed when the problem is occurring.

I'd start by testing at night or in a dark area, lights on, hood open and start trying to wiggle any heavy electrical connection you see, and watch the lights for change.
