I rescued a non working Galaga cabinet out of someone's garage... paid $25 for it
Broke into it ;-p and found that it has a few bad fuses. I pulled the game board and tested it in my test rig and it runs perfectly.
Pulled the monitor chassis and it looks great...
I disconnected the main PSU board and started from the AC line filter. Got 120v from the filter but nothing out of the ISO transformers... I then saw that the fuses kept blowing after i changed them.
The only thing connected is the 2 ISO transformers (monitor and Midway psu transformer). I then saw that there is continuity between the AC outputs on both ISO transformers. Disconnected them to make sure...
That cant be right ?.. So im guessing they are bad ? Is that what happens when they (ISO transformers) go bad ?..
