Maintenance: Electrical system
Electric welding
Disconnect the positive and negative battery cables.
Then disconnect all the leads to the generator.
Always connect the weld clamp to the component be-
ing welded and as close to the welding point as pos-
sible. Never connect the clamp to the engine or in
such a way as current can pass across a bearing.
IMPORTANT! When welding has ceased, plug
in the connector and connect the leads to the
generator before reconnecting the battery
cables.
Electrical installations
Defective electrical insallations can generate stray
current from the electrical system. Stray current can
impair the galvanic protection for the propeller, pro-
peller shaft, rudder, keel, etc. and cause damage due
to electrochemical corrosion.
IMPORTANT! Service on the boat’s low-current
circuit should be carried out by a person with
electrical training and experience. Installations
or work with shore power equipment must only
be performed by an electrician qualified for high-
current installations.
The following points must always be taken into
account:
1. If the shore power line is connected, it must have
a protective earth on land, never in the boat. The
shore power equipment must also be equipped
with an earth fault breaker.
The shore power equipment (transformer, con-
verter, battery charger, etc.) must be intended for
marine use where the high-voltage section is
galvanically isolated from the low-voltage sec-
tion.
2. Electric cables must be run and clamped so there
is no risk of it being exposed to chafing, moisture
or bilge water in the keelson.
