So I had a flipper on the cellar playfield always sticking, so I replaced the solenoid. And now upon start up the F4 solenoid fuse blows on start up. I thought my soldering job was poor so I reinstalled the old solenoid, but it kept blowing the fuse.
Now with A9-P3 and A9-J3 disconnected, the game fires up fine. Which is leading me to believe that I did something wrong when replacing the solenoid. Also at the request of a fellow pinhead, he suggested moving up to a 10A fuse, but when I did, I got a burning smell. So back down to 8A.
Any ideas what I should look for?
