Thanks Lucas for the follow up!
Today, I recieved a Lithum battery back up with an manual switch to engage the back up battery. I'll try and get it installed and tested in the next few days. The fix is to try and smooth out or rather, remove the voltage waves by passing the current thru the battery back up.
My alt is a plane power (brand new) so we're testing to see if the ap is sensitive to the voltage waves in my existing power flow and that could be causing the pitch and roll action in my ADI II.
My current power flow is being drawn from my main bus so power is already flowing from my existing 12 v battery, thru a breaker on my main bus via a stand alone circut to the ap. Here's hoping for some good results.
Again, If others are experiencing this and have found a solutions please post. TT is wanting to chase down a fix. I've had a couple of PM so I'll keep posting to get this down and squashed.
