While i had the old girl open i noticed something strange the fuse for the lights had blown. Why is this strange you ask?  Because the scoreboard was still lit up.  When i replaced the fuse the scoreboard went out and the playfield lit up dull untill the fuse blew again and the scoreboard came back on. During all this none of the relays inside the machine moved so why is it changing from the scoreboard to playfield? Any one with any ideas?
