[Elecraft] Help - Elecraft Shutting Down

[Don Wilhelm]

Ron,

Most problems of that nature are not a problem with the K3, but a 
problem with the power system.

Check your power supply and the power cord.  All connections must be 
tight and the PowerPole connector that plugs into the K3 must have the 
contact blades fully inserted into the housing.  Look at the business 
end of the connector - if you can see two metal ends (both the latching 
spring and the contact blade), the contact is not latched - push it 
further into the housing until it latches behind the spring.
What is the voltage reported by the K3?  If it is low, you might have a 
problem in your power supply.

73,
