Quoted from jstree:Hi there!
I bought a Project counter force, and have run into a strange set of behaviors:
things i have done:
new rottendog power supply grounded to speaker
docent harness from power supply to CPU
Repinned Connectors from CPU to DRIVER BOARD
All fuses checked, all coil resistances measured OK
Had bad Q relay coil, replaced with new coil.
new Niwumpf System 80 Board
the problem:
The unit powers on just fine and goes into attract mode
can cycle all coils ( Coin door stuff disconnected tho) and all lights and switches thru niwumpf. Each switch test fine, etc no noticable problems.
Start a game and the soundboard plays the first couple sounds.
The first time the ball touches a switch ( yes, ANY switch!!) the LED on the Niwumpf board flashes 3 times, locks up and displays a couple very bright random characters on the displays.
confused, as the switches test fine. if it was a short/accidental contact on the switch matrix , it would be only when one switch trips.
Im stumped with a hypothesis that fits the facts. sound board? ( why would sounds work in test but freak out CPU during game?) harness connector? (theres no common wire between all). Some kind of loss of 5V power? ( the main capacitor has been replaced on the bottom board but i think thats 12vdc anyway?)
Im stumped... any ideas?
Mine does the same thing and I'm currently working with Ace on the problem. Additionally, my Niwumpf had a strange flickering issue with the lamps in attract so he sent me a replacement board hoping it would fix both problems.
The new board corrected the lamp issue, but I still get the lockup at game start with one bright character in two displays. Unfortunately, he no longer has a Counterforce to test with, but I'm happy to do whatever testing is needed as he updates code.
An original Gottlieb MPU with a Flipp sound board works perfectly in my game, so I doubt you have any other issues with your machine.
