How Do you change the battery on a NZ2000?
How Does Aviation Mic Circuit Work?
Short story:
Buy one of these elements and some clip leads and try it.
Long story:
Seems like the basic problem is to get wide voltage swings like a old carbon mike would produce from a electret element as per this explanation
This Mic schematic gives a clue.
This list seems to be the long way around the horn.

good deal.
Now
these guys

are talking about drilling out an airbud and mounting a mic elemnt within.
This allows recording of stereo phonic sound, just the way you ear would hear it.
Sneaking recording devises into concerts and such.
What if you took your idea of a In-The-Ear speaker in one ear, and put a MIC element in the other ear. You should be able to record the human voice, through the ear canal, and do away with ambient wind noise?

How do I build up pitot/static hoses?
Freon service hosekit to scavenge the nice end fittings. Each kit offers 6 fittings, so order 2 kits and you will have plenty. They have a nice soft flare seal that is replaceable. Destroy the end crimp. Purchase 3/16 soft rubber service line. Cut to length and have a hose shop crimp new brass sleeves.
You need to end up with at least:
1 Static Hose, 30 Ft with a T, two 10 foot hoses. Long enough to wrap around the fuselage to reach the static ports.
1 pitot hose, 30 Ft with a T, at least a 6 foot on the end. Long enough to reach to each pitot tube.
This does not speak to the airplanes that will need to have the Pilot, AND copilot AND Standby Pitot/Static to be run simultaneously Two more t’s and 4 short hoses required for that.

Why does the Numner 1 Gen Switch trip on a 900
When 6PA cover is off, USE PLASTIC TOOLS. Lots of exposed high power 28VDC.
1.How sure are we that we did not put the bad APU GCU in the number 1 position this spring(During APU Uncommanded Shutdown troubleshooting)? How sure are we that we did not put a bad EXCHANGE GCU in the #1 position.
2.Has 8P1 Been swapped? Tap on 8P1 while Generator is running.
3. Backpin GCU pin P. Watch this voltage while the generator is running. Should be ~27 VDC. fluctuating voltage would be a symptom of the failure.
4. A poor connection at Pin F of the GCU could cause the internal voltage regulation to fail. Check Pin Tension. Ring all the way out to Generator B lead
5.Visually inspect CR17, CR23 4.Remove CI1, Remove 6PA panel plug A and megger the leads on CR17, CR23
6.Remove 6PA panel plug A, and megger the Plug a Pin U to ground. Check the harness side going forward to the red switch.

Early June: CI1 and CI3(?) swapped (Switzerland)
HES 1 replaced with new. (Switzerland)

How do I trouble shoot an XM weather

Good Morning Butch,
I received an email from Andy Brown that the XM is still inoperative on VP-BMB. I called XM toady and asked if the account is active yet. They informed me the receiver currently installed is still attached to Honeywell’s demo account. The demo account consists of Aviator Pro level service. They could not tell me when this account will become inactive. Longtail should contact XM and set up an account for receiver ID# CE6NK0CA (800-985-9200).
XM said you should still be able to receive all data associated with Aviator Pro on the demo account. I would suggest the following steps for troubleshooting this issue:
1) Activate the account with XM.
2) Do a system refresh using the ID CE6NK0CA at xmradio.com/refresh just prior to the next flight. The refresh should be requested while the aircraft is outside with a clear view of the southern sky and have power available for up to 45 minutes afterward.
3) Inspect the receiver for a red led with power applied.
4) Check for power and ground at the receiver. (28VDC at pins 18 and 19; GND at pin 37)
5) Check center/shield resistance of the XM coax at the receiver with the antenna connected with a digital meter. It should be around 30 ohms.
If these steps do not yield positive results I would like to connect an EFB to the receiver data connections that the File Servers are currently using to see if we have a File Server issue. Can you provide the Part Numbers of the File Servers?
Thanks,
