I am experiencing trouble with the current sensor. I am using the attopilot 180a. In mission planner it does not detect any current flow. I thought it was a problem with the Pixhawk but after speaking with 3D Robotics we chased down all of the known possibilities. Or so we thought. They sent me a new Pixhawk and I began setting it up as before. After setup I gained additional problems as well as the Pixhawk not reading the current flow. I have double checked all of my settings in mission planner and all of my connections. As a test I connected a multimeter to the outputs of the attopilot. I noticed the voltage for the volts output (which seems to be working in Mission Planner) reads 1.51v when my battery measures 23.7v. on the current output i notice the multimeter reading 2.3- 111mv as I increase the throttle on the quadcopter. My question is this. Is this a normal reading on the attopilot 180a board? If so, how do i get Mission Planner to read these values. If not, what what possible fixes are there. I performed another test with the 3D Robotics battery monitor using a 4s battery and it too does not read the current flow. I am baffled.

the additional problem i gained was the new Pixhawk even when setup to motor spin at start up does not. I am leaning on issues on the Pixhawk but that does not explain the problems on the first Pixhawk

Thanks again for the help.
