Ok so a little while ago my Jurassic Park went down and narrowed it down to the power supply. Now mind you before this everything was functioning in the game. I got a new Xpin power supply, the cpu booted up fine, ready to go....hit start and the ball doesn't come out of the trough. When I hit the flipper buttons it also make the solenoid in the raptor pit go off but not the flippers themselves. Tested all the playfield switches in the test menu and all the switches in the trough. I thought that maybe there was something disconnected that would cause a problem with the switch matrix but I've looked and found nothing. Anyone have any ideas? Thanks.

I wasn't getting the right voltage to the main board and it wasn't going through the boot process. Before I put the new board in it wouldn't even do the T-Rex test.

I went into the test menu and tried to test the coils. I couldn't activate any of them until I got to coil#11 which is the GI Relay. After that I was able to fire the coils for the slings...the jets...ect.

Oh my god...things are worse. I didn't think about checking the playfield power board and upon doing so I discovered there was a blown fuse @f5 which is the power for the flippers...great.. I replaced the fuse and then the fuse for f9 blew. I replaced that one which is another 5A fuse....turn it on...watching to see what happens and all of the sudden smoke starts rolling out of the raptor pit. I'm waiting for the plastic to cool down so I can take it off and look at the coil. What the hell is going on here? For a guy whos only had Gottlieb, Bally and Williams games I don't know why this one is being so problematic.

Thanks for the help guys. That will get me started. ^_^
