6.5 MAINTENANCE AND CONTROLLING OF THE ELECTRIC
SYSTEM
DANGER:
When the boat is connected to the shore power, the ZINC anodes must be
controlled often. If the anodes are damaged or filled with “holes” there can be
something wrong with the shore power system or the marina electric system or any other
near boat or a close electrical system. Disconnect immediately and do not connect until
the source is found.
DANGER:
➢ Clean the battery surfaces on a regular basis to prevent short - circuits.
➢ Check if the ventilation holes are open, so that gas can exit. (Starter battery or
service batteries are “gel” batteries and need no ventilation.)
➢ The battery poles and the cable shoes must also be kept clean and greased with
acid free fat / Vaseline to prevent corrosion.
Fluid level in the cells (does not apply to GEL batteries):
Control the levels by opening the plugs on the batteries. It should be at least 5 mm over
the plates. If the level is too low, fill it up with distilled water. Do not use water from the
tab. It contains minerals or pollution and can harm the batteries.
DANGER:
Do not use open fire when you control the liquid level. The gas that develops during
recharge is explosive. You can smell it. It smells like “rotten eggs”. Do not use open fire
if you smell something strange or similar to this, until the cause is known or found.
Possible errors:
See enclosed user manual from the battery supplier.
