Curiosity

[jhetley]

Took a malfunctioning UPS apart, unscrewing this and unplugging that. Found the traditional black sooty area of the circuit board. Looked like a power transistor. It let the magic smoke out. In theory, I could repair it. But tracking down replacement parts for a piece of electronics that is more than ten years old? Anyway, the battery should still be good and may fit one of our other units.
