Arnold, Thanks. This is a good clue about your
Maramu. I will find my wiring diagram. It is very small
and difficult to read, but I'll study it and try to
put it in a format you can read.<br><br>No response
is necessary. David

David, I'll get back to you after the first of the year. It is possible you were wired for both 120v & 240. I had a Maramu that was. If you have a diagram on board I'd be happy to review it. Arnold

Arnold,<br><br>This is excellent information and
advice. Thank you! I would appreciate very much a copy of
your wiring diagram. Since I am the third owner of
this vessel, I am discovering and slowly understanding
my electrical system.<br><br>I want to keep the 220
volt system for Europe and the Caribbean and add 120
volt for the United States. My electrical panel has 12
volt and 220 volt. <br><br>My shorepower plug on the
boat is 50 amp 125v/250v. My very large original
battery charger<br>says 120 - 240 volt. I do not have a
transformer, unless it is part of the battery charger.
<br><br>Is it possible that my boat was already wired for
120 and 240 by Amel? <br><br>Of course, I do not know
whether the 50amp 125/250v female plug on my boat was a
modification after the boat was built, or if so, whether it
was wired correctly.<br><br>Any other thoughts? RSVP
& Thanks.<br>David Lambertsen, s/v Have Fun!

I had my SM wired for both at the factory. I
assume you will want to be able to connect to 120v shore
power. The simplest way is the way Amel did it. Get a
120 to 220 transformer. Run a new 120v cable for
shore connection. Connect the transformer's output to
your 220v system. If you intend to use the boat in the
Caribbean or Europe you will want to retain the 220v
system. I'm assuming your charger is also 220v input. You
should have a simple plug in arrangement to change when
you switch from one to the other. If you like, I'll
be aboard over the Xmas holiday and can get at my
records and send you a wiring diagram. Incidentally,
because you have a transformer you'll be protected from
shore current driven electrolisis. Arnold/Pagan

Bonjour, mes amis les Amels...I sail 1989 Maramu
258, which I moor on the Eastern Shore of the
Chesapeake Bay, on the East Coast of the US. I am sailing
the Chesapeake now as I rebuild this boat, which I
bought 1.5 years ago in Puerto Rico. It was then named
"Tansanit"; now I call it Have Fun! My two teenage sons are
my crew. I plan to voyage in a few more years, but I
need to work. <br><br>I am very interested in learning
what others have done in the US to convert the
shorepower electrical system from 220 volt to 110 volt. Can
anyone advise me of how to keep the 220 volt systems on
my electrical panel, while adding a 110 volt
inverter/charger? What have you done?<br><br>I wish everyone fair
winds and safe seas.<br><br>David Lambertsen, s/v Have
Fun! Maramu 258
