I recently picked up a Gottlieb Mayfair, it's my Fall/Winter project. Before I start tearing down for a restore I want to get the machine working properly, but I'm having some startup issues. The score motor is constantly running when I drop a quarter start a game (is this the only way to start a Gottlieb? On my Williams, the left flipper switch turns on the machine). I've checked a few initial things, the score reels on both players reset to the 0 position properly. I've also tried to eliminate the coin door as a problem, by removing the jones plug then jumping the slam switch and momentarily jumping the start button and I get nothing.
Can anyone point me in the right direction of where to look next, what other switches could be stuck causing this problem or anything else. Also, I'm still somewhat a repair novice and this his is my first Gottlieb EM.
