Throughout the past year I have been working on and off on my Devil's Dare restoration. I'm almost to the point where the game runs 100%, but there's just one problem holding be back!
I replaced the majority of the header pin connectors, sprayed with dexoit on others, and have installed a new rotten dog power supply and Ni-Wumpf driver board. I wasn't going to go with the driver board, but since I plan on picking up another system 80 game or two in the future, I figured it would be a good idea as a quick diagnostic tool. The board is great because theres lights indicating circuit failure..
this is where my problem comes in:
--the lights on my replacement board all indicate a ground issue (i think). "E10, "E7", "E4" are all lit and from what I gather on the ni-wumpf website, they should not be on.
--I know I need to perform the grounding mod, but I don't see how I would incorporate these modern boards into the modification...
why I believe I have a problem (symptoms)
when I finish a 3 ball game, the solenoid located under the right flipper will automatically "knock" 3 times in a row and credit my game. I have played devils dare at funspot and this issue is not there.
sounds can be intermittent - sometimes they work great without issue, other times certain sounds/music will be distorted. I ran the sound board test and I get the "ahhhhh" and "beeepbeeep" sounds, which I think that indicates a working board. the system diagnostics has issues when it arrives on 17. The sound cuts out...
