I power my 2.6 board from both sides with 2 becs.  the input side bec failed and sent 12 volts to the input.

I have been using the APM boards for 2 years and thought I was being safe by powering with 5v becs.. I had no idea the bec could fail in such a BAD way, by just becoming a passthrough!

Now board does not not respond on usb and doesn't work.  Is there anything I can do or is it completely dead.

thanks for a reply.

  • check the resistance of the 2 fuses. You may have just blown a fuse
