Hi,
I believe your PS reading is too low. The PS reading on the KX3 should be
at least 13.8 volts. There is a polarity diode so your ext power supply
should be 14+ volts.
At least this what my KX3 needs to charge.

Good afternoon all, I installed the KXBC3 in my KX3 last night and it had
no error messages or problems.....up until now.
Here is what I did and what is happening.
1. Batteries that are installed are Ansmann 2850 MaH NiMH brand new min
charge on them if any.
2. Put time on KX3 for 16 hours of charge time and left the Astron power
supply for full 16 hours.
3. In the morning after charge time tried to turn KX3 on with just battery
power. It would not and found out needed to lower min voltage from 10v to
8.5v.
4. After doing this the rig came on and was fine on battery power.
5. Took rig to the park this morning and it failed to start again. Double
checked at home to make sure the new min volt setting saved and it did. I
then moved the min
setting to the lowest value which was 8.2 volts.
6. On the display I am getting the following now PS. 13.6 volts (not sure
way that as voltage on my Fluke meter at the Jack before it goes into the
KX3 reads 13.8v)
BT is reading 8.8v but is is fluctuating from 8.1v to 8.8v at times.
Now even with an internal battery reading of 8.8 or a little less the rig
should still turn on?? The only other thing I can think if is the 2850 MaH
batteries need more than 16 hours of charge time?
