An old gal my Ex knew had a problem with the light no coming on in her garage, the switch was in the kitchen by the door, and about a 30 foot causeway between the house and the garage. 1 check power to switch, ok check switch, ok check the other end in the garage,, nada,, now this means somebody has to crawl through the crawl space in the causeway celling, which was full of pink insulation,, OH and did I mention it was about 85 out side and sunny. So in I go ,with my tracer in hand crawling through a mountian of pink stuff, and it is singing quite cheerfully and then stopped about half way in the middle, so I start digging, figuring I ll find some place a where some critter chewed through things. And what to my wondering sweat filled eyes should appear ,,,, but a fuse box with a disconnect! Someone that built the causeway, ran out of wire and use it for a J box. However they didnt take out the fuses, just connected the wires, both positive and return to 15 amp fuses!!! Good thing I had a couple wire nuts and a roll of tape in my pocket cause I was figuring critters. Turns out her hubby wired the place, so I said nothing, I was picking fiber glass outa my hide for days
