I've got this over at Pinside, as well, but I figure it can't hurt to ask here, too. I'm having an issue with fuses blowing in my World Cup Soccer. At first, when I tried starting a game, F112 would blow. I disconnected J106 and J107 (output to the flashers and coils), put the playfield up, left the coin door door open, and turned the game on. The game booted up with no issues. When I closed the coin door, I blew the main fuse. After further tests, activating the top coin door switch blows the main fuse.
I tested BR3, and it tests fine. Now, if I disconnect the Fliptronic II board entirely, and disconnect J102, the game boots and starts (with no coils, working, of course). If I plug in J102, the game blows the main fuse instantly. Any ideas? It seems as though BR1 is a common culprit here, but I'm not sure how BR1 could be an issue when the Fliptronic II board isn't even connected to anything. Thanks!

Re: WCS94 blowing main fuse
When you say "main fuse," are you talking about the one by the service outlet or a different one?

The one by the service outlet.
Re: WCS94 blowing main fuse
Just a little clarification on this: if J102 is plugged in, the game blows the main fuse as soon as the coin door is closed. If the coin door is open, the game boots fine.Now, if I disconnect the Fliptronic II board entirely, and disconnect J102, the game boots and starts (with no coils, working, of course). If I plug in J102, the game blows the main fuse instantly.
Re: WCS94 blowing main fuse
Figured this out. There was some old flux on the power driver board that was causing continuity between some of the pads. Cleaning up the flux took away the continuity, and the game works again.
Re: WCS94 blowing main fuse
Wow, Flux usually isn't conductive (as far as I know). Congrats on the fix
Re: WCS94 blowing main fuse
Yeah, I looked it up afterward, and apparently a lot of flux formulations have some (low) conductivity. I always assumed flux didn't conduct, as well.

Re: WCS94 blowing main fuse
Best to clean up flux anyway, it will corrode copper over time and cause other problems.
