At the house that I live in, we have a solar panel that charges a ~12V sealed lead battery, which is then hooked to a power inverter and used to power some household devices. One of those devices was a boombox, which had the ability to be powered by 8 'C' alkaline cells in series.
I got the great idea that it would be more efficient to avoid converting from DC to AC then back to DC inside the boombox. I checked the voltage on the battery (almost 14V, but that's to be expected), then used my voltmeter leads to join the battery to the boombox, paying attention to the polarities. When I clipped the second lead in place, it started to melt within two seconds, and smoke was coming off it. The boombox's internal components had noticeable heat rising off them; it doesn't work anymore.
While I do view almost starting a fire as a sign of success in any experiment, the fact remains that it didn't work and worse, I don't know why. Anyone have some insight?
