Spent 3 hours hunting a short until I tried the hair dryer trick
Had a service call on a 15-year-old house in Phoenix where the porch light kept tripping the breaker. I pulled every damn box apart looking for a chafed wire or a bad splice. Finally remembered an old timer told me to hit suspect junction boxes with a hair dryer on high heat for 2 minutes. Sure enough the insulation softened just enough on a buried wire nut that it started arcing and tripped again. Has anyone else used heat to find intermittent shorts?

Hair dryer trick beats my method of just crying in the crawlspace.
