I recently installed the Tru-trak 
http://www.trutrakflightsystems.com/ttfsproducts.html altitude hold (altrak) 
and found it to be fairly easy to install.  I like the one button operation 
and it holds the altitude perfectly.

My problem is that when I key the mike (ptt)  and the altrak is turned off 
the indicator light come on.  When keying the ptt and the altrak is turned 
on I get the flashing light, like when first starting up.  I haven't had a 
chance to determine if it causes a dis-engage of the altrak system or not. 
I also note that my ptt causes my fuel gauge to head off toward empty.

Any ideas as to what I have going on?  Any suggestions for trouble shooting? 
I sent an email to TruTrak, but have not heard from them.  The rep I bought 
suggested that I separate the ptt wires from the bundle coming up into the 
back of the panel.  I haven't tried that yet.

Thanks for any input and thanks for all of the great ideas that I get from 
reading posts on LML.
