I am bench testing my EFIS and have connected the AHRS and magnetometer. The EFIS start up page indicates "AHRS Communication: FAIL"
To verify it is getting power, I placed a meter on the magnetometer pigtail which gets its power directly from the AHRS. It shows that is is receiving full battery power (12.5 volts).
I then tried to check the output wires from the AHRS to the EFIS at the EFIS connector but wasn't sure how to set the dial on the electrical meter. I think I got very low reading on the brown wire and negative number on the yellow. Not sure what these numbers mean if anything.
Any thoughts on how to bench test the AHRS? Or should I just send it in to GRT?
