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.

Yes checked AX/BX relays. Game now reliably does start up sequence with the start button. Hold (R) relay energizes and then releases during start sequence. Game over and first ball still on after start sequence complete.
