Hello everyone! I have been trying to get this Dancing Dolls up and running. I think that I am really close. I notice that the L (red pop bumpers and targets) and Y (yellow pop bumpers and targets)relays activate when a target is hit, but do not remain on. This means that the red and yellow targets and pop bumpers are never worth big points (lame). From this video (https://www.youtube.com/watch?time_continue=4&v=htuKUSIz2uo) it looks like they should be held on.

If I manually trigger the relays they will stay on. I have tried to trace the circuits out, but am getting frustrated.

I believe the key is in the normally open switches on the L and R relays. When they close they do not seem to energize the coil and the relay opens back up after its initial closure.

Any suggestions?

Thank you!

It looks like there are a number of normally closed switches that are part of the hold circuit. One at the Outhole, one on G and also one on the score motor at 4C. This assumes the Red target switch is actually scoring. If not, there are other things upstream of the ones I listed.

Thanks, This is what I thought, and when retracing the wires (Motor switch was easy to find and test, same with out hole) I found the switch on G and found an unsoldered wire on that switch. I bet when I get back later tonight and solder that back it will work. Stay tuned and thanks for the assist. Sometimes it is good to get someone to talk it through and un-complicate things.

I hate soldering on the relays as there are always a bunch of wires in the way.
