Looks like you are right. I would have exceeded 0.5A with the other 3 servos anyway. I didn't have power supply to the Output Rail. My mistake. I guess I was confused by the new supplied APM Power Module (rated 2.25A) and the absence of the JP1 jumper.
I tested and found continuity across the fuse near JP1, which I hope is not a bad sign.
Well, I didn't have a second power supply to the Output Rail. My mistake. I guess I was confused by the new supplied APM Power Module (rated 2.25A) and the absence of the JP1 jumper.

Below is my revised Electrical Schematic. I believe I have it right now. May have costed myself an APM in the process tho.
Here is a revised schematic with the mod you mentioned and the rails corrected. The Pan servo is a Henge MD260 with 600mA draw. I did not exceed the max by much, but that may have been the culprit.
I am not sure what to try next on the board. There is no apparent damage to it, but I can not get into "Logs" on the Terminal to erase them, and nothing else seems to make a difference. Resetting EEPROM, loading Arducopter or other versions of the firmware result in the Mavlink not being able to complete the connection.
If you can get to the terminal screen to do the reset and you can update the firmware and it all responds, then maybe you don't have too much if any damage to the board.
I found that the APM can be very picky about being connected via a USB hub. Sometimes it works and sometimes it doesn't. I ended up connecting directly to the back of the desktop machine when at home. What currently works and what does not work exactly? Is it just getting a connection to the mission planner (other than the terminal screen)? Does terminal work?
Yes, Terminal works.
The first line I get is always: 3No dataflash inserted 3COMPASS INIT ERROR
I can get response in all the terminal commands (setup, test, reboot, help) except logs. When I type 'logs' there is no response.
I can upload 'some' versions of Ardupilot and Arducopter firmware via Mavlink, but none of them work. Most versions fail partway through upload. I have Arduplane 2.70 on it now. The AHRS never gets past "INITIALISING" in any firmware.
I am connected to usb on back of computer. I've also tried a different computer.
Looks like you have a broken board then going by the missing dataflash and compass errors. Perhaps someone more familiar with how the hardware is connected up may be able to know of any possible fixes, but without dataflash being detected it's not surprising that the logs command fails :-(.
Thanks for the input Kieran. I will have to find out who is doing APM2.5 inspection and repair. In the mean time, looks like I will be ordering a new board :-(
If it were easy and free everyone would be doing it and the adventure would be over.
