Basically, we should be able to fix this via the forum if your willing to get your hands dirty a bit.

Im not familiar with gen 1 Zac games... ive only worked on Gen 2, but essentially, the games work very sinilar.

The under playfield fuses are there to seperate power to the coils from the boards.
Each fuse is in series with a row of playfield coils.... on Gen 2 this is AFTER the flippers.. so flippers will work but not solenoids.

On Gen 2 there are 2 fuses.. both should be 3A SLOW BLOW... make sure what you have is Slow Blow.. fast blow cannot handle the inrush current and will pop instantly.
If fuse is correct, then follow the power line through its daisy chain to each solenoid... chances are one of these is locked on, short, etc.
Disconnect the faulty coil by removing the wires... dont join them together.. this acts as a short also..... just tape them up as they sat on the coils ( so 2 seperate taped bundles).
The game would now be able to be played but wiothout this coil.

If the fuse is popping at start up when all solenoids fire, then chances are you have a fast blow installed or smaller current value fuse.



Basically, a blown PF fuse indicates a fault  away from the boards
