Here is some of the chronology of what happened:
1) Bought a un-working game and replaced the MPU with an Alltek
2) Rectifier board pins are in bad shape and the wires were soldered directly to them but once I replaced the MPU the game played except the backbox feature lamps; Shoot Again, Ball in Play, etc did not work
3) I had a great time playing about 400 games as is then a drop target broke
4) I fixed the drop target without un soldering anything and reassembled
5) I turned on the game and only got GI lighting
6) Thought I might have blown a fuse so I removed all fuse from the rectifier board and checked. They were all good. Checked fuse under playfield which was good as well
HERE IS THE BONEHEAD MOVE:
When replacing the fuses, I accidentally inserted F2 fuse between F2 and F3, thus leaving the F2 fuse open and shorting (I suspect) the other. When I turned on the machine...here is what happened:
1) Audible buzz, MPU had red LED and Cap on right next to heat sink on solenoid driver board started smoking
2) Turned off the machine and ordered a Rottendog replacement driver board
3) verified all fuses (double checked so as not to make the same bonehead move!)
4) Turned on machine MPU red LED and Driver board Red LED

Is the rectifier board the problem? What do you think the problem with the backbox feature lamps is? I Ordered a new rottendog will install it soon.

Thoughts?
