Good deal.  Just out of curiosity, what voltage did you measure?

Comment by Dennis Fuente on January 8, 2014 at 2:16pm

I have checked the voltage at the regulator and it is above 3.3 v so i have ordered a replacement for it my hope is that nothing else has gone down.

Thanks for the help

@Dennis,

This regulator is being used to take the 5V board input and regulate it down to 3.3V.  When a regulator fails, it could fail multiple ways, no output (Hi-Z), output grounded, or output shorted to input, for example.  This one in particular seems to favor failing with the output (normally 3.3V) shorted to the input (5V).  You will need to perform the check documented in the video on the page that I linked to confirm if this is indeed the issue that you are observing.  It's a pretty simple test if you have a basic multimeter.  If that's the issue, replacing the regulator should get you back up and running.

Ok so help me wrap my head around this the regulator blows but it dose not blow open as i would expect it leaks a higher voltage i think the chip quality is the issue.

  So after the regulator is replaced everything works normally ?

Thank you Bo Wingo! This is exactly what I need.

Take a look at the "AC3.1 & blown 3.3V regulator" blog post to understand the issue of the blown 3.3V regulator and how AC3.1 uncovered the issue.  This information should also help you zero in on identifying whether this is actually what happened to your hardware.

@John McGrath and others. I am curious about the regulator that has been mentioned. Do you have a location on the board or schematic? I ask because I bought a used APM 2.5 and have had issues with it concerning updating to 3.1. I'd like to replace mine and see what my results are.

Comment by John McGrath on January 7, 2014 at 2:14pm

Guys if you have a bad regulator why not fix it? Most are all DIY types on here get a soldering iron (low wattage) and replace it then get the better update. If mine was blown thats what I would do.

So i went back and installed 2.9b and the same thing occurred bad gyro health prearm health bad on the flight data page and i cannot arm the ESC's funny it all worked prior to updating to 3.1 is there a way to fix it ? not going to purchase another APM any help appreciated.

Hi Sean 

 Yes i see that this is a common problem after updating to 3.1 i would think that 3dr would take care of the issue guess not. 

Thanks for the information i am going to try and go back to previous 2.9
