Struggling with a Card Whiz I'm working on.
Coin switches and start button won't energize the start relay. If I energize by hand it appears to start up but the game over (Q) and first ball (U) relays remain active.
So far in my troubleshooting I found a bad solder joint on a switch on the hold (R) relay. I also found a switch that didn't go through the plastic latch correctly on the first ball (U) relay. Those have been corrected.
