[ale] fried innards

[Calvin Harrigan]

So the power supply sank 30+ amps at 12 Volts (360 watts) via the 20 
gauge or so wires long enough to melt the connector?  That is a 
questionable supply, as far as safety is concerned. Which is why I 
recommended replacing it with one that has over current protection.
