No "Data" from Compass or AHRS sensors

[Johnjthomas44]

Need some help! I have a Voyager with Odyssey G2 B2.0.0.2 and A 1.2.0.2. software. Last flew the aircraft in October and everything worked perfectly. Due to a variety of non-aircraft reasons, haven't flown the aircraft since. I changed out the starter solenoid and main battery as part of the aircraft's conditional inspection and noticed when I went to start the aircraft in January I had Red Xs on the EFIS and the little Infinity instrument says something to the effect of, "no compass data and "no AHRS data". GPS data is good. I've checked all the normal connections on the back of the EFIS panel and all are tight as are the connections to the sensors, any idea on what could be going on? Thanks.

Either your AHRS and compass sensors are not getting power (check if you can see the usual flashing LEDs on them) or the data connection to your EFIS is not making contact - if the aircraft has been standing for some time perhaps some corrosion on contacts ? Try removing and replugging the connectors.

Thanks Rainier, I'll try it!

The SP-4 red LED flashes with power on the system. The SP-6 light is on steady but faint and kind of faintly pulsates rapidly but doesn't blink (on, off, on, off), the light pulsates from dim to very dim, and back and forth. Any ideas? Thanks.
