Looking for some help. I thought I'd worked these problems out but I ordered parts and have replaced them and the problems are still there.
Firstly, when I start a game, it puts a ball into the shooter lane followed by another a second or two later. I can't play a game as it wants to spit out an extra ball at the start of each game and then gets confused during game play. When testing from the menu, the optos in the trough for ball 1, 2, 3 and 4 all read the same way, open when there is no ball and closed when there is (I might have that arsed about but I think that's right) but ball 5 says closed and stays that way. I tried swapping optos around on the boards which I had read somewhere helped someone out but it didn't help. I have replaced both opto boards for the trough now but the problem is exactly the same. Testing the shooter lane switch and it operates as expected so I don't know what could be causing the problem. Anyone got any suggestions?
My next problem is that the scoop for TV/Final Draw doesn't recognise when a ball goes into it. When I first turn the game on, the solenoid for this scoop fires 6 or 7 times which I'm guessing is a sign that it thinks there is a ball there and it's trying to kick it out. In testing the optos from the menu it doesn't change if there is a ball dropped into the scoop or not. I figured the only thing here that could detect a ball being in there would be the optos so I replaced them but the problem is exactly the same. Once again, anyone got suggestions?
I'd really appreciate thoughts on what to test or even diagnosis from those that know or have had the same problem(s). This was a grail pin for me but unfortunately it only worked for a little while before I encountered problems. I've got to add LED's, Cliffys and mirror blades to it yet, but am holding off on that as I want to know that it's playing properly before I pull it down to replace bits.
I've read many pages of this thread but still many more to read. It's an awesome thread, it's just so big.
