Ouch! Yeah, the 3 decade fade on Bally blue can look green. Trace the wires back to the transformer lugs to make sure you have the right one in the right place.

Plug in JUST J-2 to the rectifier board and try it. J-2 is what brings the A/C to the board. If it blows then, your problem is in the cab wiring. If it doesn't blow, but it does with J-1 added, your problem is in the play field. More difficult to find, but not impossible. Don't get discouraged!

That would be one way. Start with the obvious. Unplug the coin door and try again.

Quoted from fatcake:

There's a quick hum and buzz before the fuse blows. Is that just the roasted board making that noise or does the transformer make that noise?

Could be either or. Bummed to see this latest post. If you only have 6 and 7 on J-2 plugged in and are still blowing F-1 chances are that BR1 is blown and shorted. You can verify that with your multimeter on diode check.
