Would an ADHARS failure cause erratic amp indication? I have two busses and two alternators along with two batteries. At the same time as the amp readings (volts remained constant at 14v plus) the PFD tumbled and other readings like wind vector and speed also was erratic. I am assuming that the 14v indicates that the Alternators are charging and the erratic amp readings are EFIS related and associated with an ADHARS problem... Correct?

An AHRS failure wouldn't normally cause an erratic Amp indication. A short interruption in the power to the AHRS can cause the attitude on the PFD to drop momentarily drop out. I have never seen the AHRS cause a current irregularity.

Thanks Ben.. Flew 3 hours and all was well from start to shutdown... No transients.. Nothing abnormal. Electrons!! I think there is a connection somewhere that needs attention..also dual AHARS may be in the works
