Had a guy worked for me in the Air Force... decided to bypass a circuit breaker using the same logic.... look for the smoke. F-15 Attack Radar system. When the smoke cleared... pun intended.... was over a half a million dollars in damage.Back in the day......I was a pup...there was this mechanic @ local shop - one of the best, fastest line mech's ever. He was semi-literate though, so when it came to wiring issues he'd "jumper the fuse and watch for the smoke" Lol (really). When he first started work, the backlog was 3 months, after a month, it was a week.
Not the best troubleshooting method.
