Altemator 12V 35A (SOOW) S. E. V.
The alternator produces 3-phase altemating current. The altemating outputs of
each phase are rectified by means of 6 silicon diodes (3 positive and 3 negative
diodes). During starting, the field current is fedto the rotor trom the battery via the
regulator.
The alternator must therfore only be run ij the battery is connected. Ij a battery iso-
lating switch is fitted the engine must not be started until battery has been switched
on.
Use of an altemator ensures continuous charging of the battery even if the engine is
idling for long periods.
The SEV altemator bas an integral electronic regulator.
.
Follow the connection diagram precisely. Incorrect connection will probably
damage alternator or voltage regulator and repair will be expensive.
In addition to the above:
1. Check carefu1ly that all connections are made as shown in diagram.
2. The altemator must never be run unless both battery terminals and the
regulator are connected. Remove the altemator drive belt before discon-
necting the battery.
3. If the battery is to be charged trom an extemal source, first disconnect bath
battery terminals.
4. When welding on board (steel hu1ls), disconnect the battery negative terminal
beforehand.
Starter, BOSCH
It is very important that the starter should not be exposed to sea water. The engine
must not be started if the level of water in the bilge reaches to the flywheel. Pump
out sufficiently to avoid splashing the starter.
Battery
The battery should be contained in its own box made of wood or special plastic and
it should be positioned as near to the engine as possible. The battery box should be
0( weU ventilated and the battery firmly secured.
Check the battery regularly. Top up with distilled water to keep the electrolyte level
1/2 cm-1 cm above the plates. After topping up in cold weather, run the engine for a
while to ensure circulation of the electrolyte. Keep the battery terminals and cable
clamps clean. Remove any oxidation and coat lightly with vaseline. Make sure the
cables are tightly clamped onto the terminals.
The electrical equipment is not covered by the engine guarantee.
