A four-block fuse holder held up against four commonly fused wires leading to a factory-installed 20A fuse holder.
The four-block fuse holder installed in the pinball backbox, with each fuse holder wired to a separate GI string from the light board, coin door, and Playfield. The other side of the fuse holder is grounded together and attached to a lead going to the transformer return.
My Williams Pokerino pinball machine operating with all four fuse lines individually fused. This game is running LED GE 44 globes so can operate with 5 amp fuses for each circuit.
Very glad I did this General Illumination mod to my Williams Pokerino pinball a few nights ago.
It popped a (now isolated) Playfield GI 5A fuse and that lead me to discover that it still had incandescent bulbs installed instead of LED ones.
6.5A draw on a 5A fuse was not going to last long.
