I have been corrected - last word of 1st paragraph should have been 
'watts' instead of 'volts'.
I trust everyone knew that!

David,

The KX3 may still be running by virtue of the internal batteries if the 
KXPA100 power drops, but that will not prevent the KX3 from turning off 
the PA ON menu and dropping the power to 5 volts.

Check your power cable - look in the end of the APP connector.  If you 
see the end of 2 pieces of metal (both the spring finger and the contact 
blade) the contact blade is not latched, give it a push from the wire 
side until it latches.

Check the connections at your power supply, they must be tight - if you 
can move them at all, they are not tight.  Also check the fuse and 
fuseholder.  The fuse must make tight contact with the fuseholder contacts.

73,
