Hey guys, purchased a Black Hole about a month ago, but am just now getting to it. I put in a new Vreg, and a new Schewmmer sound board in there, but everything else is pretty much factory. When I boot the pin up, I get 000000 on all the displays so all looks good initially. Then, when I coin up and hit the start button, I get a flashing 0 on the Player 1 display, and a 1 on the Ball in Play display (which I assume is normal). However, no ball comes out of the trough, and the flippers are non-functional. Any idea what my troubleshooting path would be at this point? Driver board?

The fuse was blown out so I replaced it. Once I replaced it, one of the three balls would release from the trough when starting a game, but the flippers still wouldn't flip. About 30 minutes later, I smelled something burning. Sure enough the fuse blew out again. I'll check the connectors tonight. Could bad connectors at the driver board be a culprit for the fuse blowing out?
