I picked up a acnc last week and after a few games, the servo fuse blew. It calls for a 3 amp fast blow. I think its the first time a machine I had called for a fast blow fuse. All the 3 amp fuses I have say slow blow on the package or nothing at all as far as fast and slow go. Can I use a 3 amp slow blow? Any input why my fuse could have blown?
