Batteries…
- Wear rubber gloves during the test as, in case of accidental
spillage, the acid contained inside the batteries can be harmful.
- To obtain a reading, fill the syringe with electrolyte contained
in each battery cell and read on the float the value of the specific
density. The higher the float on the electrolyte level, the more
charged is the battery.
- A value of 1.125 (generally marked in red) shows a state of
discharge, a value around 1.135 (yellow) denotes an intermediate
state of charge and a value of 1.260 (green) a state of maximum
charge.
• Readings can be influenced by a number of factors including an
elevated electrolyte temperature, which, because of expansion,
would give a low reading even in a state of full charge. Cold
electrolyte would cause the opposite effect. Best reading is
between 18
°
and 20
°
C.
• When topping the cells with water, readings might be unreliable
for a few hours: the added water might not mix readily with the
denser electrolyte. Repeat the test after a few hours for true values.
• If, during the tests, you realize that one or more cells constantly
show a lower value of charge than the others, it is very important
to isolate and change the battery as soon as possible: it would
damage the other batteries of the bank very rapidly.
12 Vdc sockets
◊
The 12 Vdc sockets are made in such a way that polarities can not
be inverted accidentally and therefore only the corresponding
plugs can be used.
• In the G.S.43' four 12 Vdc sockets are normally installed as
follows:
- Fwd head.
- Galley
- Aft head.
- 12 Vdc electric panel
Fuses
◊
The anchor windlass push-button switch is protected by a fuse
located inside the 12 Vdc electric panel.
◊
Each navigation light (red, green and white) is protected by an
extra fuse located inside the 12 Vdc electric panel.
