Default Flashing Battery Light

Hi all,

Have a NB8A running MSPNP Pro. For some odd reason the battery light will randomly come on and off when driving causing the car to stutter for a split second. Only happens when off the gas/initially pressing gas pedal.

Alternator just replaced, battery holding charge and belt has been tightened. Thinking it may be ECU related but unsure, any ideas on how I can start to diagnose this?

A lot of a few events might help, just to look at voltages.

Does anyone have picture references to all grounding locations by any chance?
