Low battery on K2 without battery

[Scott McDowell-4]

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?

Scott,

What does the K2 internal voltage (tap DISPLAY) read?  How about during
transmit too?
If it is substantially lower than the voltage at the power supply, look
for a problem with the power cord or the connections to the supply or
even with the supply itself - substitute a charged automotive battery or
a gel cell for the supply as a test.
The voltage will normally be 0.2 volts lower than the supply because of
the series protection diode, so more drop than that is significant and
indicates a bad connection somewhere.

Scott:

You might also check to see that the shorting block on P7 on the Control
Board is in the correct position. If you have it in the EXT position,
then, if I remember correctly, you will get the Low Battery warning.

Sorry...
