Have a Dixieland bingo pinball that starts and plays normally, however I can't continually "flip" the coin switch to add additional credits to add more cards and increase odds. I can manually activate the multi-play relay but nothing happens. If I manually add credits on the replay register I can then add more cards and increase odds. My question is, is the Start Relay AND Multi-play relay supposed to activate simultaneously and make it possible to add more credits by continually activating coin switch? If someone could enlighten me on the sequence of events that will allow me to add multi-play credits I would be very appreciative. Thanks to whoever solves this.

Thanks to all for your input and expertise. I now see the reason for running the replays down to zero before any more coins are accepted.
