Hello all! In November I bought my first machine, a Bally "Dogies," and I've been fixing it up little by little since then. When I got it, the score motor ran constantly but nothing else happened. I've fixed a million little things and got it playing really well (thanks to pinrepair.com and tips I picked up from this forum), but it still has a few issues that I could use your help with:
1) During games, the machine power occasionally cuts off completely. This happens maybe one game in 20 or 30. I'm guessing that the hold relay is just letting go if something else in the game draws a lot of current, but I haven't been able to connect this to any specific in-game occurrence. Very frustrating! Do I just replace that coil (which looks pretty crispy) or is this a symptom of some other identifiable problem?
2) This game has a "cactus juice score" feature, which increments by a single digit when certain skill shots are made. Currently, the player 4 cactus juice score does not reset at the beginning of a new game, and this causes the score motor to run continuously. The player 4 cactus juice score solenoid is operated by Reset Relay #3 in the backbox. Looking at Reset Relay #3, there's one incredibly obvious loose wire hanging out right next to it, begging to be soldered back in place. But, the only switch with an empty lug actually has TWO empty lugs. No other loose wires are visible. One wire and two lugs, and I have zero idea what to do. The schematic (which is in German!!) hasn't helped me in this case, but maybe someone has an idea...? I can provide photos from the backbox. Schematic is attached to this post.
3) Regarding the match feature and knocker: I don't understand how the match feature is supposed to work. The 0-9 unit seems to work fine. But if the 1's digit of the score matches the match number at Game Over, isn't it supposed to increment the credit unit and send a pulse to the knocker? I don't understand how the position of the 1's digit could be known, other than at 0 and 9 when the switches change. I occasionally see that the credit number has incremented, but I haven't yet heard the knocker. I've also tried to run up the cactus juice score manually (I'm not a great player) which is supposed to score a replay -- no luck so far.
4) Is this game supposed to have a second bell? There's a clapper (but no bell) on the bottom of the 0-9 unit, and my other machine (Bally Sea Ray) has a bell mounted there.
Thanks for any and all help!
