Just recieved a deluxe bowler that was shipped to me. The game is very clean and was restored at one point. The seller said it worked prior to shipping, but I can't get it to launch the ball. I checked the lever switch and it is making contact when engaged but the coil is not firing to release the ball. I checked all the fuses and the jones plugs are all tight in the backbox. Any ideas on what I can check or where I can find schematics?
