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.

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.

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.
