I want to power the input side of my APM 2.5 with 10A bec. I also want to use a 90A Attopilot to monitor current and voltage.
I have it set up very similar to my APM 2.0 and have used the same pins as for APM 2.0, A1 A2 for the voltage current.
I have checked the settings in MP and A1 and A2 are selected appropriately.
I do not get any current readings though. I have set up properly in MP for the Attopilot.
Is there something I am doing wrong?
I have JP1 removed, and power output rail with a separate BEC.
Am I doing all this right? Maybe my Attopilot is not working?
I have pretty much the same setup with a APM2.0 and I have no problems with it.
Does anyone have a working setup similar to what I am trying to do?
Maybe I have to use the Power module with APM 2.5 to get voltage current?
Thanks!

Yep that was it.. I didn't even think about that until I was looking very closely at the board through a scope.. then I saw "in" and Out and thought, oh crap, I did it backwards.. Sometimes I just make life hard on me.. haha.. thanks for all your help..
Maybe somebody will learn from my mistake..
okay I found the problem... hardware failure...
But does anyone know what the missing component is and whether I could replace it with a "std size" component that I could possibly solder in place?
any thoughts?
here is a datasheet for the this.. It doesn't help me, but maybe someone here can use it to figure out what component I need?

There's a offset that can be set if required. See http://code.google.com/p/ardupilot-mega/wiki/APM_Parameters#AMP_off...(_ArduPlane_:AMP_OFFSET)
You don't need the power module.
