[Elecraft] Help with KBT2

[Brian]

Hello all, 

 

I just installed a KBT2 in my working K2.  Set my power supply to read 13.9V
on the internal K2 meter and let it charge for a couple of days.  Now that I
tried to use it I cannot transmit at all or the internal battery voltage
drops off very quickly and the radio will shut off and come back on. 

 

I get 13V on the battery terminals and at the connector that connects to P3
with my Fluke meter.  When I plug into P3 with the K2 off I still get
battery voltage of 13V but as soon as I turn the K2 on I get 11.2V on the
internal K2 meter.  I also get 11.2 volts at P3 with my Fluke and the K2 on.
I thought it was just a bad battery that can't hold a load but I tried it
with a known good battery and it's the same voltages.  I have no idea where
to go from here.  

 

By the way, I have a KPA100 that plugs into P3 and it works just fine.
