No Output in Out 2 ( counting begins from 0)

after getting the entire thing setup. it turns out i dont get any output on out 2. so i went back and did the dancing servos test and it remained true, i looked at the soldering to make sure there were no unintended bridges, looked clean. what could it be, as a temporary solution i was wondering if there is a way to code for the apm to treat in4 and out 4 as in2 and out2 so i can solve the problem and get airborne. any help with that/? as far as the out 2 issue how can i test whats exactly going on, i seem to be getting power but no signal for the servo / throttle to respond to commands. In the CLI it clearly shows through the tests that in and out on 2 are fine , so it must be a physical problem either the powers not comming through as it should or there is no servo signal coming through? ways to test this and troubleshoot would be really appreciated.

Hi Mahmood, this does sound like a hardware issue and it looks like you already checked your board from top to bottom. Still, can you provide clear pictures of the whole board, front and back?

So what i have done is i used a bunch of jumper wires to test exactly where problem is with regards to the pins that come out of out2, the power works fine , its the pin that send the servo its signal, so i just did a continuity test to make sure there weren't any cut traces till the Ic3 and its fine, so im still wondering what next to test ?

I am sure this must be a hardware issue. ill post a video of the malfunction... there must be a software way around it though unless out 2 is specifically always going to be the motor in which case i cant run the autopilot correctly
