Hi

my autohelm 3000 compass died recently. I took the control unit apart and
found three copper wires which act as brushes to send signals to the compass
unit. In my unit these wires are loose, are they suppose to be loose??? It
looks like they should be soldered to the printed circuit board. anyway I
cleaned the wires(brushes) and the commutator rings on the compass unit and
put it all back together. surprisingly It works. I'm worried about how long
it will work if these wires(brushes) are supposed to be attached to the
circuit board.

Anyone ever take one of these units apart??? Any Info would be appreciated.

thanks
