I am trying to finish up repairing my black knight, system 7 and have a few questions. Please fill in any blank spots you can. Here are my issues:

-When I turn the game on, it goes into attract mode, no errors. New power supply. Everything is receiving the right power. How do I start a game? My displays dont work, do I cant tell what is going on, but pushing the start button to the left of the coin deposit does nothing.

-My displays dont work. Getting proper voltage, but a couple of the HV drivers are BLAZING hot....I assume I just need to replace these?

-Many times, when I power the game on, it goes into attract mode anf the Multi-Ball solenoid rhythmically fires about every 2 seconds. Pushing the diagnostic button stops this, as does unplugging the switch inputs on the driver boards. Anyone seen these? Maybe a short somewhere? I read one spot where someone mentioned the game wont start and will fire this solenoid if it is not sensing the right start up conditions, like number of balls.

-My CPU has a couple DIP switch banks on the upper left. For the life of me, I cant find the use for these, and they are not in the manual. I know they are from early system 7 games. Anyone know what they are for.

Please help!
