Hopefully someone can help. I have a Bally Paragon I'm working on and the voltages are too high on the rectifier board. I have rebuilt the reset circuit on the MPU (acid damage) and installed new proms/roms (I jumpered the board correctly, I have checked and rechecked). I also rebuilt the rectifier board with all new components. The MPU does 6 flashes, but I can't get it do the 7th.
I installed a known working rectifier board and transformer into the machine and got nearly the same voltages, so I have ruled out those components. I am out of ideas though and any help would be appreciated.
Here are the voltages (all connectors attached to game):
TP1: 6.42 VDC - Should be 5.4 VDC
TP2: 258 VDC - Should be 230 VDC
TP3: 15.08 VDC - Should be 12-14 VDC
TP4: 7.13 AC - Should be 5.7 to 7.3 AC
TP5: 54.5 VDC - Should be 43 VDC
Here are the voltages with J2 only connected to the Rectifier board (isolated from the rest of the game):
TP1: 6.44 VDC - Should be 5.4 VDC
TP2: 186 VDC - Should be 150 VDC
TP3: 13.16 VDC - Should be 13-16.5 VDC
TP4: 7.45 AC - Should be 5.7 to 7.3 AC
TP5: 46.3 VDC - Should be 43 VDC
Any ideas what I should check next?
Thanks!
