Welp, it appears that there's another problem when installing Speedball. We've double checked the instructions of Speedball three times now, and we can't find anything wrong/missing with Speedball wiring.
There seems to be no power from 12 to 1 and 5. Currently, the D1 LED is not lighting, nor are the LEDs on the small "A" tube are not lit. (In total 3 LEDs not lit.) The rest of the LEDs are on. When it comes to voltage checks, here are the numbers we had from testing.

Thank you so much again, and sorry for the problems.
