. thanks very much for your paitence,at least i have learned how to test ac now.and now i know my way around this circuit,i will remember the lesson well,p.s. globes are 44,that i can get to,slings.mitchell has ordered some 555 spotlights to lighten the lower playfield area.

sorry about putting you through all that. I measured the string voltage on the backbox insert and it was 4.5v. We know now that all your gi circuits through the boards are fine.
that is why your other data east looks dull also.
