Hi, having problems with a AUTOHELM 1000. Does anyone have a schematic or
experience with this unit.
Thanks

I should know this but I just can't get my brain around it.
I have a data logger that will accept 4-20 mA or 0-2.5VDC.  I want to track
the current going to the refrigeration compressor which I figure will be in
the range of 0 to 25 amps (to be safe for start ups).

My husband wants a portable gps for our 18ft.outboard Wellcraft. He also
wants to use it for the car on occasion; but one made for boats primarily.
Santa doesn't want to spend too much. I'm looking at the Christmas circulars
and have no idea where to get one, maybe a marine store ...

I will be spending some time while my boat is cold and shrink-wrapped to
plan,
test and install a new computer system for navigation and entertainment
purpose.

Doas anyone know of any such program?
Best regards
Rickard

Is this economically (or otherwise)feasible? I understand that they draw
very low voltage/current making them real easy on batteries while providing

I'm not quite sue if this is the right place but any info would be helpful.
Could anyone here please provide me with a circuit diagram for a soundboard
which plays the submarine diving noise? I'll need a complete list of
everything in simple language due to be being new at this.

Can anyone provide information as to why the Horizon SL45 gauge is
back-ordered so long? Is there an alternative 4" round gauge to fit in
a bulkhead cutout? My sailboat originally had a datamarine guage (no
longer available). I already put in the Airmar ST650 paddlewheel that

I have a problem with a Centennial Style 5102 antenna.
The antenna simply "does not get out".
The boat owner mounted the antenna to a short stainless steel mast
on top of his houseboat. The boat has a metal roof.

I have an 8KW Westerbeke diesel generator (about 12 years old) which
has an odd vibration issue at times.  This happens most often under
moderate to heavy load and lasts for 15 to 20 seconds at a time.  The
vibration is so violent that the guages are impossible to read and it

I am in the final stages of building a 38' steel ketch and am currently
looking at the installation of a SSB system (Icom M802 / AT-140). I have
read back through the forum postings and gained some good knowledge, however
am wondering if anyone can help out with some the problems ...
