Quoted from Marv:According to the guide the red and white wires are back to front
The guide is based on Bally who have white at pin 1 and red at pin 8. Stern did it opposite.
Red and white are for the general illumination which is AC anyway. But best to follow the manufacturer coloring layout.
So i've re-pinned the connectors on the TA-100 all showing correct voltages. I can't seem to get the 5v on the SDU-100 Rev C.
- Re-pinned connectors J3 and J4
- Rebuilt 5v section (apart from 2.2 Cap)
- New Voltage Regulator (tested on bench)
- Ground mods done and 5v TP1 -> Tp3
Now i can give the board 12v on the bench and all is well, but as soon as i plug it into the backbox no 5v, i've checked pin 12 on J3 and its giving out 12v unreg.
Its got me scratching my head some what..
Any ideas?

- New Voltage Regulator
Post a clear picture of the 5V regulator - there are low spec China fakes going around..
