I am a novice to Pinball repair but I have recently acquired a Gottlieb Royal Flush 1976 pinball machine that powers on and the lights come on but the score motor starts running as soon as the machine is powered on and does not stop. Pressing the Start button on the machine does nothing. I have started researching and have learned some valuable information and am starting to get a greater knowledge of what is going on and should be happening, but I have not been able to fix this problem yet.
Update: When powered on the Tilt Hold Relay (H), 1st Ball Relay (U) are set off.
Last Ball Relay (BX) goes on and off.
I figured why not try posting to a forum and see if I could get some results there while doing research.
