Tod,
Somewhere between your power supply and the anode of D2, there is a problem.
It may be a high resistance in a connector or a burned PC board trace or a
relatively low resistance (but not zero) path to ground which is dragging
down the power supply output. With the power source de-energized,
All checked out OK
I just completed the voltage checks on page 27 of the assembly manual
Here's a comparison of the results when working versus now
U1 pin 1 was 4.94v now 19.5mV
U3 pin 6 was 6.05v now 2.47v
D2 Anode was 14.83v now 2.7v
D2 cathode was 13.75v now 2.5v

Ok, you have an open circuit somewhere between the power supply and the
anode of D2 - there are only a few pieces involved - the wire in the power
cable, the male connector, the female connector in the KX1 and a bit of PC
board trace going from the connector to the anode of D2. Continue the

Greeting all,
I have a mail into elecraft, but thought I'd throw this out to the list.
I took my KX-1 out camping a few weeks ago, where it was working
fine. I finally unpacked it yesterday, and much to my dismay, it
seems to be dead.
Here's what I discovered:

Tod, look for a short in the +12 circuit to ground. The swollen batteries
suggests they were feeding lots of current into a dead short for a long
time.
Open the unit and do the resistance checks at the top right column on page
54 of your manual. If those checks disclose a short, follow the PCB

I am assuming that you are the builder of your KX-1. Go through the
troubleshooting and testing sections in the manual. Post what you find.
