[Jukebox-list] Rockola 1438 - LAST PROBLEM?

[wbabbott at cox.net]

Ron, I guess it's a ladder switch, there are three banks of buttons. I took a meter and checked the contacts between #1 and #2 "at rest" and there's continuity at all points except at bottom points where pushing the button send signal to pinbank?.. Any other ideas?

> I'm down to my last problem on the 1438. When I push the #2 selector button, I hear a buzz in or around the pinbank, but nothing happens. Of course it happens on all four selections that match the #2 selection on the four sided selection drum. All other push button keys work and make selections, BUT, only #1 pushbutton works AND removes a credit in the accumulator. All higher buttons including the non-working #2 button fail to remove a credit from the accumulator. I figured I might have a problem with the #2 pushbutton switch. So, with much consternation and frustration, I figured out how to remove the push button switch bank (not an easy task). I examined the #2 button and switch, but I don't see anything out of place. The #2 and all other buttons properly operate the sliders and return to there proper position.
