[DG] [DG11] Autopilot Drops into Standby and other issues

[randy@onlinecruisingguide.com]

Hi There-
We're using an ST6001+ autopilot head and course computer for same (not sure of model, but 2002 era).

This system is also networked via STng to 2 MFDs (A65 and E98), radar, AIS, STng bus, converter, Tridata, Wind instrument, etc.

Issues:
1) Phantom “Next Waypoint” prompts when there is none in the system, and we’re not even on a route, simply a Go To cursor, for example.

2) Unit drops from Auto into Standby, typically with no alert and no warning, of course. Sometimes it will beep. This is most often when autopilot is in a very low-strain situation. Sometimes (but not often) in a heavy seaway.

I have already re-done every electrical connection at main course computer (gray box), and confirmed voltage is not an issue (we run lithium batteries, voltage almost never lower than 13.1). It often will do this on flat water, motoring with 13.5+ volts in the system.
