Im having issues with my gameplan machine and I need to know what happens voltage wise at test points 3 and 4 on the mpu board at power up. I believe I have a reset circuit problem but I'm running out of things to replace to resolve it. If you could test your machine and post the results it might lead me on the right path. Thanks in advance.
