Hello, I am brand new to this site as I just recently picked up my first pinball machine. It is a 1975 Chicago Coin Red Baron. I got it at a good price and expected I'd probably need to put some work into it since it was stored in a warehouse for many years. I haven't had much luck finding information on this particular manufacturer or machine and wanted to make sure that I am going through the start up process correctly since I'm very new to this and haven't been able to get it to fully start. The machine powers on and when I hit the left flipper I get lights throughout the entire machine and sometimes when it powers up the cylinder inside will make 2-3 turns but not every time. I can also get it to turn by giving it a little push. This is where I am stuck and wondering if there is another step to the start up procedure that I'm missing. When I put a quarter in, it drops all the way through the coin mech, but it doesn't seem to register or acknowledge any credits and it does trigger the little wire on the bottom of the coin mech switch. I've pressed the credit button and nothing happens as well. I have looked everything over and do not see any loose wiring and I've gone through and cleaned every leaf switch I could find. I partially feel like it could be a tilt/ slam switch issue just because when I attempt to trigger one of the anti cheat switches, nothing seems to change although I am also unsure how the machine is supposed to respond when tilt/slam is triggered. The machine seems to be in relatively good shape and I was told it worked before it was moved to storage although I usually take that line with a grain of salt. I welcome any advice to help me get further. It would be helpful to know of there is just simply another step to the start up process that maybe I just don't know. I have worked on plenty of arcade machines, but pinball is a whole new level and a little intimidating. Thank you
