[Elecraft] Low battery on K2 without battery

[Scott McDowell]

Hello
For some reason the low battery messages keeps poping up on my K2
in the receive mode.
I have the p7 jumper on the internal side, and have tried it on the
external pins, but I still keep getting the low battery message.
On my first K2 I  had the battery deal turned off, but don't see anything
in the manual on how to turn it off on this one.
It's drawing 240 ma on receive and the internal volt meter doesn't work
but the power supply voltmeter shows 13 volts.
Any ideas?
