I have an interesting problem on my Funhouse that I'm not sure how to tackle:

If the flippers are activated at the same time a ball hits any of the inlane/outlane switches, I blow fuse F112 which cuts all coil power. This was after a playfield swap I just finished. I've verified all the connections on the lane switches and flipper coils.

The flippers and switches work fine otherwise. Only when they're activated at the same time doesn't the fuse blow.

Thanks in advance for any guidance.

Have you confirmed fuse ampacity and if it should be fast acting or slow blow?
I would start with those easy things to check.

Do your two opto switches work? I ask because I had a similar situation after my restoration and it was blowing the same flipper fuse. Turns out I had the connectors on the opto board swapped. They are one of the few connectors next to one another that are not uniquely keyed on that game. Luckily I didn't break anything aside from my pride.

Yes ... it’s the correct fuse.

I think I spoke too soon. The fuse was wrong, or at least I think so. The electronics shop I brought them from told me they were slow-blow, but they looked different from what I’ve seen. I purchased more tonight from a different shop and they didn’t blow at F112. However, I’ve hit a string of fuses blowing in different sockets. I definitely found some things out of sorts wrong fuses and one shorted fuse. The symptoms remain but I think I’m getting closer. I had to cut my troubleshooting short tonight, but will revisit tomorrow.

Thanks for the help guys.

check the flipper coils and make sure the diodes arent broke

Ok then, this may likely not be a wiring issue ... stoopid-ass me mounted the flipper linkage upside down, so the end of stroke tabs never make contact. Face meets palm. Fixing today, then will report back.

Um ... yeah. Root cause was having the flipper linkage reversed, so no end of stroke at all... all good. Moving on.
