i folks.  Like most of us, I have a ST4000+ wheel autopilot.  Problem is it is 
ery prone to doing 'crazy ivans' (reference from Tom Clancy's Hunt for Red 
ctober).  I have tested the flux compass following RM's diagnostic guidelines 
nd it checks out ok.  I don't think my set up has a 'course computer, just a 
control head' ... does this make sense?  Could this be an electrical supply 
roblem (short, broken wire?).  Anyone with any insight?  I don't want to have 
o replace the whole system if it is an easy fix or just one bad component.  
nyone have an old but working control head and/or compass ... I would like to 
se the 'swap and test' method, versus paying for expensive technician time to 
rouble shoot with test equipment.  Happy to pay 'rental fees' for these 
omponents and outright purchase the parts that fix my problem.  Any thoughts 
rom the forum?  Alan Hull #67 Holland, MI
