[Elecraft] FUSE BLOWN AND NOW WHAT?

[Manuel Wilches]

Hello everyone:
this time I have to come forward and confess with full exposure in broad day 
light. I made a terrible mistake!

My KPA100 tested beautifully untill I got to the 20A power supply test (page 
45). As I turned on the K2 (#8 step) nothing happened. I checked and I had 
blown a fuse (the one that comes with the kit). I switched off everything 
and went back to figure 32 (page 38)...I had reversed the wires on j4 when I 
soldered them on the KPA100 board.

As I was taking my time to unsolder the cables, clean the pads etc. I 
thought I could  turn on the K2 on its own (as before) with my low power 
supply and nothing else attached to it. Well here comes the suprise...I 
cannot turn on the K2 at all. I have the 13,0 volts allright, coming out of 
my small PS but nothing happens. What did I blow away?

J4 was plugged in P3, of course, when I blew the fuse.

Your comments and recommendations will be very much appreciated.

Thank you
