Check fuse ratings and types before first power-up

Look for over-sized fuses (an 8 A where a 5 A belongs) and fast-blow fuses where slow-blow are specified, not just blown ones. Most fuses are in the backbox, but solid state flipper games also have fuses on the flipper board on the left side of the cabinet.
