Just an update . Game seemed to be working fine when I first set it up .Thought it may have been a connector or something came loose during transport . Took the translite out to have a check around and noticed the little red LED's on the main CPU board - when you turn the game on the bottom one comes on and the top one comes on for about 3 seconds or so ( middle one is unlit) . After about 3 seconds the top one goes off and the middle one blinks constantly with the bottom one remaining on the whole time . Can't think from memory but the blinking means there is a problem somewhere correct ??? ( Been a while since I've owned a Williams).

Haven't really had much time to check it out but will have to download a manual and see what I can find .
