Gal 3 five vdc supply

I have had intermittent s/d for a few weeks,super reset car everytime .finally saw active faults …saf processor..EPROM FAULT. Pic pal inhibit high .also no coms to fire service and hall I/o boards .shows cs open but no saf actually open .I have 4.7 to 4.8 on supply after reset had 4.8 steady …I’m heavily leaning towards the supply,Prior calls were full of junk Bc of super resets but com losses seemed steady before his resets .But GAL I TAKE IT WITH A GRAIN OF SALT ,is this behavior indicative of a weak supply ?im not good with gal nuances,MCE KONE I know will wack on 4.8 never saw a gal do this

The Galaxy Controllers I have like there 5vdc to be at least 5.2vdc. When it drops below 5 I start to have issues. Most of the time I just adjust it with the pot on the power supply.
