Any help is appreciated - experiencing 2 problems with Bank Shot, add-a-ball from Gottlieb 1976.
Problem #1) When score achieved, have it set to 60,000 points, and a WoW/extra ball is achieved, the WoW doesn't light up on backglass right away, the "knock" does sound but, the solenoid is sticking (humming occurs) on the WoW stepper (am assuming) - until ball drains or goes into a kick-out hole - at which time the humming stops & the WoW lights up on backglass.
Problem #2) Upon last ball draining, when bonus points are awarded, the "knock" sounds, but the WoW light doesn't come on & doesn't award an extra ball. The "Game Over" light comes on instead.
Thanks for any suggestions.
