Picture of panel for info.
A/p = KFC-200

On the ground or during flight the AHRS Light Fail will come on and drop the autopilot intermittently. This is what it is supposed to do per the STC.
Few minutes/seconds later AHRS light will extinguish and A/P can be re-engaged.

I have tried -
EA-100 was sent to Aspen for 24-Hour shake/bake/freeze and tested good.
2 different Aspen 1000 PFD's
3 different ACU's
Replaced Ethernet cable
Checked wiring.
Any help from the Aspen/Avionics Guru's out there is greatly appreciated!
