let me start by saying I am a VERY HAPPY, long time Dynon customer. Here's my issue: my red cube stopped reading flow. was working. stopped. 0.0 flow reading. So I've read some threads and saw where I needed to verify +12VDC on Pin 15 (red wire) from EMS. I read 0.0VDC on this pin. I read 3.2VDC on Pin 14 (yellow wire) which sounds like close to what I should see. All readings taken from the EMS harness and with red cube disconnected, because I suspect the cube is fine and that I've somehow lost the +12VDC. Is there a little tiny fuse in the EMS I may have blown? Does the cube HAVE to get its +12VDC from this pin? Can it be powered off of a 3 AMP breaker, for example? Thank you.
