Hey there. I know this is a pin site but I recently purchased a Rush the Rock sit down arcade driver and none of the lighted buttons or marquis is working. I am a bit of a newb at this but i checked all the bulbs and fuses and none seemed blown. I was told to check the the common ground lead in the light circuit. Unfortunately, I am not sure where this is. Any help or pics of how to help would be greatly appreciated. Game plays fine, just love my lights. Thanks in advance.
