No power from RC Pins

hi to all, 

 

After several succesfull flights with my Arduplane (v2.26) i have problem.

when i plug my 3s lipo to esc, only a red led(PWR) lights up on ATMEGA 2560 board. When i plug the usb everything works great (except servo movement) and i can play with mission planner and read inputs from all sensors and rc inputs.

 

i may exceded the current trying to use 7 12gr digital servos (4 for flight control-3 for camera). wrong servo throws fried one of my servos and since then the problem appeard (iam not exacly sure if it happend before or after the new firmware update) .

i already checked for the soldered part and its ok.

 

is there eny way to reset a fuse or something? should i buy another fuse or buy another board? power the board using another trick??

 

thanks you all 

James

  • Have you had any issue with the PPM encoder after this fix?

    Hello everybody!!

     

    Problem found and Solved!!!

    it seems that servo burnout, burn this little ground line on apm board from rc pins ground to board ground

    i solderd a piece of cable from rc pins ground to board -+ holes and everything works again!! be carefull when using many powerfull digital servos with high draw.

    Thanks a lot Burt, i was hoping this to work out too.

    It seems i have exacly  the same symptoms like Dave Whittington http://diydrones.com/profiles/blogs/ardupilot-mega-home-page?id=705...  discribes a year ago, but my jumpers are solderd.. 

    a minute ago i powered apm board from + - holes with a seperate UBEC and aditionally a pluged my esc on rc rail, everything lights up but servos still dont move in any mode..

    i cant locate the fuses on APMboard, how the look like/ name? for sure nothing missing i double checked all images with my board

    i will have my polymeter back tomorow to check every end..

     

    Thanks again for helping me Burt

    I have had a very similar problem. The last time was after 2 good flights. After changing batteries, I couldn't get the yellow gyro, or red GPS led to light. I had no xbee connection. After hooking the plane up to usb I could upload firmware, but couldn't connect to change settings. I could connect to test all the hardware with the MP terminal, all tested well.

    I also when over all solder joints on the APM, tried it again same thing.

    I then loaded the Hil firmware, now everything seemed to work. I then reloaded the 2.26 again, had the same problem back again. ???

    I next loaded 2.24 firmware from the Arduino interface, It rebooted the APM and all seemed to work again.

    I have had this happen 2 times both times I had to go to older firmware, then reload the 2.26.

    Give this a try and see if it works for you.

    Hi James,

     

    I'm sure you have, but I will just ask! Did you check this page here

     

    And have you looked at this information here

     

    You can power the board in another way by following the above steps , I thought that the fuse reset itself after a power down on the APM, I could be wrong!

     

    Let us know how you come along with the above information.

     

    Regards

     

    Martin
