Hi guys, I've been running through the various steps in Pinwiki about fixing WPC reset issues and am at a point where I could replace BR2 and C5 but don't see a need. I've tested all of the bridge rectifiers and they are good.
Basically, I'm losing .2 volts from the driver board to the rom. I have a stable 5v on the driver board but on pin 32 of the game rom I only have 4.98V. I assume this is what is causing my resets? I have redone the header on the CPU board as well as the driver board and have also redone the 7 pin connector between the two. When I unplug the connector from the CPU and test the voltage directly at the 5V on pin 3 and 4 I get 5V on each.
Where on the CPU board am I losing the .2 volts before it gets to the rom? I guess the last thing I can try is replacing c31?
