Black Knight worked great for years, I tried to play it about a week ago and found 3 blown fuses. 2 of the 3 coming directly off of the transformer (2jon the right side), and the second one to the left below the power board. I am new to trying to repair my own games so please excuse my lack to using the correct terms, just learning. Note: Have not tried just replacing the fuses yet. Thanks Steeljaw St.Louis Mo.
