FREQUENCY CENTRAL Microbus (Power Supply) [BOM]

Doing some checks on the pins, i can’t seem to get a reading from the 7912 ground and other grounds on the board, could I just run a wire from the 9712 ground to some other ground? I might have wrecked the through hole.

with the 2000mA power supply, looks like @lookmumnocomputer uses a 2000mA one as well.
