I have my quad put together and a couple of folks suggested some changes in my wiring scheme to eliminate the possibility of harming the APM.
The comment that I had been following can be found here as well as the post following it. I have removed all but one + lead from the ESCs but now the APM will not power up. I double checked to ensure that the one ESC servo connecter connected to the output of the APM has 5v. It does. I double checked to ensure that the grounds are all connected to the distro ground and they seem to be.
The advice that I was given makes sense to me but, prior to me removing the +5 volt leads from the output connectors the APM would fire up, I don't want to damage my APM, but I'm not sure what else to do.
Does anyone have any suggestions as to what the problem could be.
