Well I picked up a slot machine topper to put on one of my machines. I was using the 5 and 12 volt plug inside the coin door of my Elvis to power on the 5 volts chaser lights on the topper. Really just trying to see if the topper worked as I just got it. I wasn't paying attention and put the ground wire and 5 volts wire from the topper in the 5 and 12 volts on the plug in the coin door. The machine surged then a couple coils started to fire over and over again until I could turn the game off. Well now when I turn the game on all I get is some lights on the playfield and the display lights up Stern pinball. Thats it. I checked the fuses and they all seem good. I have a rottendog driver board in the game.
