But when I did the first time test, the motors works nice (controlled by the Mission Planner)

So you mean to reverse red and black wire bec connection on the AMP ?? i'm a little afraid about that..
So that will not make S + - but S - + ??

Check your power distro and voltage out to APM/IMU, remember the red wire alwais is on center pin +

From top view connention is S + -

i've just checked the 2 wires (red at centerpin and black on bottom) with my multimeter and he says : 5,0 V

 

My power distro is good because the 6 esc makes all bip when Mission Planner make the test just after the firmware upload.

 

But i've a 3S Lipo for my Hexa. is it enough ?

I've just tested something : just plug lipo and the 2wires from an esc to test if the apm launch.. but nothing :(

And it's 5V...

No solutions for me ?? no test to do ??

i've seen 2 solder holes near outputs with + and - .. does they power the APM ? Does 5V works into this ?

 

Help me please..

I don't know if it's damaged because when i plug the usb with mission planner, all works nice ! The gyro, magneto, gps, Rx... all works fine.

So i think there's a problem with the power input... How can i check that ?
And if theres a fuse, how can i know if the fuse is ok and where it is, and how can i change it ?

Thanks guys !

I had an idea : if a fuse is dead, electricity doesn't pass through : so i've test the fuse and they are OK, so it's not that...

There's 2 fuse. one on each card and they're both OK...

I think the Imu shield is OK because it works with usb
I think APM is OK because all works with usb (the leds are on and the arducoter2 is uploaded)

So i think there's something is wrong between the 2 wires and the rest of the card...

Alexandre,

 

What are those ESCs? Do they have proper internal BEC?

 

Have your checked that ESC will output 5V from middle pin? You said that you measured 5v from bottom and middle pin on ESC connector but how about when connector is connected to APM R/C Connectors. Do other pins also see this +5v? You should see +5v between every middle and lower pins at APM 3 row pinheader.

 

Yes there are + and - holes on side of the PCB but you cannot put 5v to there, it should be higher like 7.2v.

 

3S is enough for hexa.
