Resistance is reading 0 when I connect ESC to Pixhawk Cube

As soon as I plug and ESC into my Cube resistance goes to 0. Have tried plugging ESC in one at a time and the same thing happens…

Does anyone have a troubleshooting idea for this issue? Can see full photos of build components here: https://photos.app.goo.gl/qVRPXUJ7hkRAxDGr8

Thanks for taking a look.

Where are you measuring?

Power at XT60, connected like so to multimeter https://photos.app.goo.gl/ycuAQzawdBTrh7m96

Video demonstration here, one of the ESC’s is connected upside down in the video but the same result when any one of the ESC’s is connected correctly: https://drive.google.com/file/d/1yqYsWrbrQ6F3BEp_MA-3AqEniIrBx79B/view?usp=sharing
