[CA] [CA11] Failed Rudder Drive Test

[David R.]

I have an Evolution autopilot with an ACU-400 and, I believe, a Type 2 linear drive, which was previously installed on my 44 ft cruising sailboat. Although the unit would engage and take over control of the boat it would not hold a course or allow any deviations in course headings. After updating the software I ran the Dockside Wizard. During setup the Rudder Drive Test came back as Failed. Working with your customer service on the telephone it was suggested I send you pictures of the drive unit for identification and also of the ACU-400 to determine if was wired correctly. Please see the attached photos and thank you for you assistance.
