More information about the game here. https://pinside.com/pinball/forum/topic/40s-united-pinball-machine-cleaning-question
There is no schematic for this game so I'm asking your help with troubleshooting this issue here.
-------------------------------------------------------------------------------------------------------------------------------
The game used to complete the reset sequence but now it stops with the 900,000 and 90,000 lights lit.
The 10,000 Step Up Unit is staying energized causing the loud buzzing but I'm not sure what's keeping it energized? What should I look for?
Thanks in advance,
Bruce
