Re: [Amel] Re: shaft driven alternater Sharki #127

Geoffrey. I have a common 12 volt Delco alternator that was modified by putting
a 24 volt rotor into a 12 volt stator (case). It has an internal 12 volt
regulator.  It bolted up in place of the Amel supplied alternator, which on my
maramu was a Paris Ronn. I had to remove approximately 1/2 inch from the front
of the foot of the alternator that mounts on the bracket above the transmission,
and do a little machine work on the small diameter pulley to fit it onto the
alternator. The total cost of the alternator ready to go was only $120 US. It
puts out 16 amps at 6.5 knots, twice what the original did. If you ask around, I
am sure someone can direct you to an alternator repair shop that could test your
alternator and repair what you have, or provide you with an improved version.

We have Sharki 181 with a Valeo 25 amp shaft alternator.
It is a Type A290, this number has now been changed to 510837. I it is identical
to a Motorola unit, they look as though they come out of the same factory and
use the same brush set etc.

The current replacement has a UK list price of approximately £1200.00, yes one
thousand two hundred pounds! So I would suggest that you get yours repaired or
find a more sensibly priced alternative.

You should bre able to find an auto shop that can test and repair your existing
Best of luck.

Could somebody provide the specifications on the shaft driven alternater so
that I can have my current model checked. I get no output at 6 kts thru the
water... Does any body recommend a permenant magnet alternater.
