[Elecraft] K3..Power Poles and my bad,very bad

[Howard K2HK]

I had a very senior moment yesterday related to PowerPoles and could use some help. The power supply that my K3 is powered by has an auxiliary cigar lighter  outlet. In the midst of a project (too late at night)I plugged that cable into a similiar PowerPole which turned out to be the cable from another  P/S which happens to be a 24 VDC supply.The K3 went dead in a blink. Does not restart. First, any suggestion of where to start looking? Second, although this never happened to me before  it is something to be aware of if you have several terminals dangling at your desk. Embarrassing situation!
