I recently acquired a Bally 1034 from an estate sale. It has had it's share of issues. But, it was up and running pretty quickly. But, now it seems to have an issue with the hopper. When it pays it spits out a few coins then pauses briefly like it has a jam (you can hear a hum). However, you can freely spin the pinwheel. When it does this "stop pay". If you remove the hopper and slide it back in it will then continue to pay (may have to do this once or twice).
After the pay is complete with proper number of coins. All lights come on and works properly. Now, when you play the next game you will hear the payout solenoid chatter for a couple of seconds. After the first game is played it will not no longer chatter until the next payout. Then it starts over again.
I guess one question I have is: What is the purpose of the 30uf capacitor located on the hopper?
