My EFIS-D10A has started going Attitude Indeterminate on power up and goes to its grey & black condition after a short period. I am in the process of final assembly and recently added the EDC unit w/o OAT probe at this point. All worked following the installation and the unit powered up fine. I hadn't powered it up since early December. Yesterday I powered up to do a radio check following some mic/phone jack work and the unit would not boot without going Attitude Indeterminate (it spins as if the unit is rotating).
