I'm getting some strange random resets during game play. I've had the targets reset or I just had the game do a match and game over while a ball was still in play. The game has a newer Alltek MPU and lamp driver and a brand new Alltek SDB that I just put in a few weeks ago. It looks like the one thing that hasn't been rebuilt is the power supply. It looks like it still has the smaller rectifiers. Some of the connectors have been repinned but not all of them. I'm also getting a random left top bumper firing but it doesn't score when that happens. Don't know if that's related. I've recently added some compacitors to help with missed scoring to the 100 point bumpers and the sling shots. I don't know if any of that is related. That was done weeks ago and this problem just started. Not sure where to start looking. Should I repin the rest of the connectors or should I be looking at that power supply?

I just checked it. It's actually TP6 on this board. I got 5.02 volts DC. I'll look at the diodes. Thanks.

Will do, thanks.

Thanks guys. J4 on the MPU looks brand new. One or 2 others look new but it looks like I've got some work to do.
