[Elecraft] K2/10 low battery message

[Scott McDowell]

Hello
Has anyone ever had their low battery mesage
keep coming on every five minutes on their  k2/10.
Where does this message originate from?
I have re-soldered every joint from the power
input up to the power switch and can't figure out
 where the power circuit goes from there.
 All components check good up to that point.
I even re-soldered the power switch. Anyone ever
have a bad power switch? The low battery
messages never comes on during transmit.
I have the K2/10 connected to the same 30 amp
power supply that I used on my K2/100, and
I never had a low battery message on it.
I don't have a battery installed so that is not
the problem.
I never got this message on my K2/100 running
100 watts, so I believe the problem is in the K2.
Any one know where to start looking?
