Maintenance: Electrical system
Electrical connections
Also check that all electrical connections are dry and
free of oxidation and that there are no loose connec-
tions. If necessary, spray these connections with a
water-repellent spray (Volvo Penta Universal oil).
Battery. Maintenance
WARNING! Risk of fire and explosion. Never al-
low an open flame or electric sparks near the
battery or batteries.
WARNING! Never mix up battery positive and
negative terminals. This may cause sparks and
an explosion.
WARNING! The battery electrolyte contains ex-
tremely corrosive sulfuric acid. Protect your skin
and clothes when charging or handling batteries.
Always use protective goggles and gloves. If
battery electrolyte comes into contact with un-
protected skin wash off immediately using plenty
of water and soap. If battery acid comes into
contact with the eyes, flush immediately with
plenty of water and obtain medical assistance
without delay.
Connecting and disconnecting
First connect the red battery lead + to the battery +
terminal. Then connect the black battery lead – to the
battery – terminal.
When disconnecting the battery, disconnect the
– lead (black) first and then the + lead (red).
Cleaning
Keep batteries dry and clean. Oxidation or dirt on the
battery and battery terminals can cause short-circuits,
voltage drop and discharge especially in damp weath-
er. Clean the battery terminals and leads to remove
oxidation using a brass brush. Tighten the cable ter-
minals well and grease them with terminal grease or
petroleum jelly.
Topping up
The electrolyte should be 5–10 mm over the plates in
the battery. Top up using distilled water if neces-
sary. Charge the battery after topping up for at least
30 minutes by running the engine at fast idle.
NOTE! Certain maintenance-free batteries have spe-
cial instructions which must be followed.
