*Ever* is a rather strong statement! I've been known to "short out" fuses
in troubleshooting boards with a higher rating fuse than is called for for
troubleshooting purposes, and yes, even short them out with a jumper wire
(although granted very rarely!) One example was a shorted chip that for
whatever reason, I didn't find with the VOM. Running it a short time with
the fuse shorted out heated up the chip and I was able to feel where the
problem was. Troubleshooting vs normal operation :).
