What exactly were the voltages and where did you measure them?
I can't remember, but here are some numbers from two different ARII PCBs I posted in a different thread.
ARII PCB #1 = +5VDC & 1.3mVAC
@Game PCB = +4.87VDC & 1.1mVAC
---------------------------------
ARII PCB = -8.50VDC & 1.1mVAC
For +12V and -5V I get +11.76V and -5.20V, respectively.
ARII PCB #2 = +5VDC & 1.4mVAC
@Game PCB = +4.89VDC & 1.4mVAC
---------------------------------
ARII PCB = -5.20VDC & 1.4mVAC
For +12V and -5V I get +11.97V and -8.61V, respectively.
********************************************************************
ARII PCB #1:
At C31 I got 10.3(AC) & -24.8(DC)
At -5V I got 1.5(AC) & -5.2(DC)
ARII PCB #2:
At C31 I got 8.3(AC) & -24.8(DC)
At -5V I got 3.1(AC) &
.002(DC)*
*That probably would have reached zero, but I heard a pop accompanied by smoke when the 7815 blew on the game board, which is right next to the cap that previously exploded and the red light on the game board stopped working.(See pic). (But the light started working again the next day). ?!?
Thanks.
