This Fireball Classic machine had some issues when purchased and all have been solved except one..Problem is with the 1 amp SB fuse blowing on initial power up of game..
First of all the game boots up and plays fine. New Alltek Ultimate CPU board. New Alltek lamp board.
All scoring / targets/ displays/bumpers/ flippers/etc are working fine; the only issue is the under playfield 1 Amp SB fuse.
I may have it narrowed down the problem. But need a little help solving the issue.
This is the scenario of the problem
--When i unplug the solenoid expander board and power up the game; the 1amp SB playfield fuse does not blow- the game plays fine except for the spinner not working.
--When i plug in the solenoid expander board and power up the game;the playfield 1amp SB fuse blows - the game still plays fine; the spinner works fine but the pop bumpers/kickers work at a reduced power.
I have replaced the original solenoid expander board with a newer "Great lakes Modular" version with the same results.
I have repinned the connector to the solenoid expander board. All wires match up with the original with the same results
I even have switched the original Solenoid Driver Board with a new Alltek Solenoid Driver Board - still the same results
In a nutshell- To play the game you either have the spinner working and have half power on the playfield because of a blown fuse or replace the fuse and unplug the solenoid expander board and play the game at full playfield power with no spinner.
Have anyone got a suggestion
