Picked up a sorcerer the other day. We had found a few things broken and repaired them, game plays, sounds, all controlled lights work. Only thing not working is the GI lights in the backbox and playfield. Checked all fuses. With no defects. On power supply board, at 3J9, I only have 1 or 2 volts. Manual says it should be 6.3VAC. Any ideas?????
