Yes. Your ammeter reading is out of calibration. As long as the
bus voltage is above 27 volts, there's no way your battery
could be delivering energy, I.e. show a discharge reading
on the battery ammeter.
Are those true "shunts"
http://aeroelectric.com/Pictures/Instruments/20-50_Shunt.jpg
or are your current sensors really hall effect transducers?
http://media.digikey.com/photos/Honeywell%20Photos/CSLA2CD.jpg
If hall sensors, it's likely that your G1000 battery current
sensor system has a -1.5A or greater offset that displays a
discharge even when the battery is charged and perhaps still
taking in some energy.
Temporarily run the battery cable OUTSIDE the hall
sensor. With all wires outside the sensor, it should
read zero all the time. Check the manual for any zero
adjust features that might be available. Alternatively,
ignore it. Battery ammeters are of limited usefulness
anyhow. Your original battery was probably okay if it
was still cranking the engine well. I think I'd opt to
ignore the reading.

Subject: | Re: Icom A-210 intercom |
Chris,
Mine is wired as you indicate you want yours done. It works as
advertised.
The only thing, is setting the squelch level for the intercom to
break, is not well explained. After getting the values set, there is
no method to save the setting. If turned off, it will go back to
default, which is too low for my plane. Once reset again, pushing the
button IN saves the changes. I just guessed.
I am having issues with the radio receiving though. Sent it back last
fall. They changed the firmware, and re-seated some boards. It has
worked fine till yesterday. It will not receive. If turned off, and
back on, it works fine. But for how long? I will call tech support
once again. They know my voice.

Bob,
One last question. With a carbon fiber can the ground plane be on the
inside or should be on the outside.

Kevin - funny you should mention that. Yesterday I was running the engine
with the intercom turned on, for the first time. I couldn't adjust the VOX
squelch enough to prevent it coming on, anywhere above 1,500 RPM. They
don't seem to have enough range in the adjustment. Let me know if you hear
anything from their Tech Support.

I agree..
However, since the carbon fiber is somewhat conductive and therefore
shielding in nature, I might be concerned if the thickness of the surface
(including any foam/honeycomb core material) were significant.
Significant depends on what frequency the antenna operates at. The higher
the frequency, the more critical. If it's vhf it probably won't have any
major tuning effect. If transponder, I suspect a noticeably de-tuning
effect might be noticed. I would also guess that any de-tuning can be
addressed with a slightly longer radiator. You would need proper
equipment to check that out.
Regards,
Matt-

Subject: | Re: Icom A-210 intercom |
Sam,
I got mine to work but had to set the squelch to 25 (I think) and
then push the button to save it. If I did not save it and turned it
off, it would default to 15. The default setting would open up
squelch and I could hear the background noise.
I don't know for sure what RPM, but on TO roll it would open.
My visit with tech support today was to identify my lack of
reception. I have no other problems. That I know about. I left a
message with the service manager. He is to call me back. Looks like
another trip to the service dept. for my A 210. I asked them about a
replacement radio. Tech support skirted that issue fairly fast.
