[Elecraft] KPA500

[Ron D'Eau Claire]

1) Do you have the yellow tap connected to the PS board and the other taps
mounted on the rear panel? 

2) Are the "parking" connectors on the rear panel for the unused taps
insulated from the chassis and each other?

3) Are the wires to the rectifier board (on the "Z" bracket just behind the
front panel) connected correctly?

4) Are the Primary connections to the power supply board (just inside the
left side panel) correct? 

If those things are all correct, post the question to K3Support at Elecraft
dot com. They will work through it with you. 

Good luck!

I just finished assembling my KPA500 (s/n 625).  I was very careful in
following the instruction, or so I thought.  When I plugged it in and turned
on the rear rocker panel switch, the fuses immediately blew.  I have the 120
VAC power cord and the 12 Amp fuses installed.  Any suggestions where to
start?
