Hello,
I'm totally new to pinball and have acquired my first machine. It's a Bally special forces I think I got a good deal at 150.00. The machine turns on lights up and shows game over, but when I insert a quarter nothing happens? By this I mean the game still shows game over with no credits displayed. I'm not sure where to go from here, I have checked all the fuses I can find and they are all good. When I press The test button it's showing switches are closed? It says to press test button again to exit the menu but this does does nothing. I am technical (mechanically) by trade and have understanding of dmm but not so much the electrical side. Could someone please help me out?
Thanks
Geof

Update to this, I found some stuck switches did some cleaning and now when I start the machine weapon dt flashes on the screen. Also as far as I can tell the solenoid so don't fire (flippers) so I'm assuming they won't engage without credits in the machine?( still won't register credits when the switches are tripped)
