Flow transducer zero

[MGoodacre]

Hi

I've installed a Red cube and getting not readings on fuel flow. fuel calibration has been done and set to 68,000
I have checked for voltage which is reading +12v
yellow wire from the EMS connected to the white from the red cube - is this possible to test with a multi meter if so how?
black wire connected to aircraft ground - should this be to one of the 3,13,16,17,30 pins and not to aircraft ground ?

any help please

I connected it to pin 13 and I get fuel flow readings.

FYI - all the sensors should be connected to 1 of the Dynon ground wires you can 'pair' off a ground if you have need to.

I understand the way I installed my red cube it will not work or give good reading….with the wires coming out downward…it’s not stated in the EI instructions tho! So I have to reinstall mine….arghh. And make a new support for it

Try it first. These things have been installed in all sorts of orientations with successful results.
