Add A Fuse $8

This is a highly recommended added security if your upgrading your circuit boards.  Williams pinball machines didn't add fuses between the transformer and power supply.  Any type of short coming from the transformer could potentially damage the new circuit boards.  Adding this fuse block is a must.  This installs in a few simple steps:

  1. Screw the fuse holder near the bridge rectifiers
  2. Cut either the Red (left bridge) or blue (right bridge) wires near the installed fuse block.
  3. Preferred method would be to solder on the cut wires to the fuse holder.  Wire connectors are added for convenience.
  4.  Add the fuses
