Another game I am trying to get going while on break. Here's a history of what I've done.
1. The game played but then started to go to TILT on start-up. My guess was connector issue and/or issue with Normally Closed slam switches.
2. Slam switches look good. Rebuild connector from the coin door/slam switches.
3. Replace ALL boards with new after market replacements. New power supply, Ni-Wumph, and driver board. I had these so I wanted to make sure that the issue wasn't with the boards I had in the game.
4. Replace power supply to CPU connector with a brand new connector from Docent Electronics. Replace CPU to Driver Board connector with brand new connector with diodes from Docent Electronics.
5. Game will now boot into attract mode. I can go into the Ni-Wumph settings to choose my game and options.
6. But, when I start a game, the displays go blank, no controlled solenoids work, no switches work. Only flippers and pop bumpers work.
Since I have almost all new stuff, any ideas of what to check?
Thanks, Johnie
You need to run the self tests. Do all the switches register correctly?
I suspect at least one is not, and you may have a shorted switch diode
or a switch line shorted to ground or (worse) lamps, or (worst!)
solenoid bus...

PS - you didn't mention Ground Upgrades!
PPS - Also, make sure the small transformer has a fuse on it's 120VAC
input - the fuse should be around 3/4A slo-blow.
