I've been doing all the suggested upgrades for the power supply board, ground mods, etc, and I'm finally ready to get the game going. I started by plugging in just the power supply board, and here's what i got:
TP1 (+60vdc, i have 69.5)
TP2 (+42vdc, i have +52)
TP3 is ground (and these measurements were taken using TP3 for reference)
TP4 (0.8vdc where it's supposed to be 5vdc)
TP5 (+8vdc, I'm getting 8.3vdc).
I plugged in J3 and suddenly i got 5vdc at TP4. Plug in J2 (CPU connector) and my +5 is gone again. Could anyone could send me a pic of J3 to the power supply board from their game? I think mine might be slightly off, in that pin 6 (+5vdc) is unoccupied, but pin 7(also +5vdc) has 2 wires going to it...
Thanks!
Edit: i have installed a 15,000 uf cap in place of the tall orange cap in the cabinet, all new bridge rectifiers.
