Scratching my head on this. Beginning work on project Fathom. Installed a working Weebly.com Universal MPU board with dips set for Fathom. Installed a known good solenoid driver board. Installed all 3 balls. Turn on game and after MPU gets 7th flash one feature light comes on, the outhole kicks out one ball, then another, and game freezes there. If I then take a ball and put it back in the outhole, it kicks out 2 times again, then the displays come on and the all the feature lamps come on in attract mode, but doesn't coin up and the credit button doesn't do anything. All 4 switches at the outhole test good and are adjusted. What do you suppose is going on?

Quoted from jj44114:

Did you run the switch test to check for closed switches with the balls removed?

Yes. There are no closed switches indicated during the switch test.

Quoted from Xenon75:

or you have a shorted cap on one of the switches causing havoc with the switch matrix.

If there was a shorted cap, wouldn't that show up during the switch test as a closed switch?

Quoted from TractorDoc:

I'd suggest the fun task of re-pinning the connectors

Yeah, I knew someone was going to suggest that. Ugh! You're probably right, and I am going to order parts tonight. Just hoping there was something else, subtle or otherwise to try first.

It's really going to suck if I repin all the board connectors and still have this problem!!!
