Gene,
When my ST4000 autopilot first powers up it attempts to rotate the wheel a
1/4 turn or so. I think this is some sort of self test or indication that
the unit is on. Could be related.

Hi,
I mounted up my boat's wheel for the season and connected the servo motor to
it's electrical connection on the pedistal. When I switched the power on,
my power kept switching off and on at about a 1 second frequency on the
autohelm display and my tri-data display. My GPS, which is connected to the
same power feed was having the same problem. I disconnected the servo motor
electrical connector, and the power came on and stayed on.
My hunch is that the servo motor may be defective, but it was working fine
in the fall before I dismounted the wheel, which I store inside the boat. I
am going to dismount the wheel and re-assemble the whole works to see if
this could have been caused by a mechanical problem. I forgot that the
wheel lock was on when I first switched on the power which may have caused
the problem initially.
Has anybody seen this problem on their boat?Gene Musante 617-755-0680
