[Elecraft] KPA-500 low voltage on start

Cary,

You use a Dryer plug!  While that is overkill for the KPA500, it is 
definitely OK.
If you cut the 120 volt end off the power cable, you will have a white, 
a black and a green conductor.  The white and the black wires should 
connect to the "hot" 240 volt connectors in your plug, and the green 
wore should connect either to the neutral or the ground connection 
(depends on whether your dryer plug is a 3 conductor or a 4 conductor).

Actually, if you mix the neutral and live, you will end up with 120 
volts, so I presume you have some different problem.

My 220 socket is wired like a dryer 220 socket so I removed the plug from the cable (OK per Dale at Elecraft0 and installed a 220 plug for the socket.  When I start it up the HV reads .1 (yes, point one) and 0 current.  Could I have the neutral and live backwards? I have a call into Support but he's on another call so i figured maybe someone out thee knows?
