Fuses; Battery - Mercedes-Benz 300TD 1980 Owner's Manual

Fuses

The fuse box is located in the
engine compartment.
A summary of the protected
equipment is printed in the fuse
box cover.
Fuse arrangement in the box —
starting at engine side, proceeding
from inside to outside —
upper row: odd numbers
1 ,3 ,5 etc. up to 13;
lower row: even numbers
2, 4, 6 etc. up to 14.
Fuses must be replaced, not re­
paired or bridged.
Spare fuses are stored in the fuse
box (observe amperage and color
code).
Determine the cause of a short
prior to replacing a burned-out
fuse.
After replacing a fuse, screw on
the fuse box cover firmly.

Battery

Check the fluid level in the cells
from outside approximately every
4 weeks, and more often in summer
and in hot zones.
The fluid level must be between the
lower and the upper markings.
Only replenish with distilled water.
Do not use metal funnels and do
not perforate the diaphragm of the
battery overfill protection.
Electrical System
The battery is filled to the maximum
level when the water level in the cell
filling chamber stops going down.
If battery acid is to be extracted
for battery diagnosis purposes,
perforate the diaphragm with the
hydrometer or the tube attached
to it.
Coat battery terminal clamps with
acidproof grease. Keep battery clean
and dry.
Only tow vehicle with the battery
connected.
Only charge battery with the rapid
charger when it is disconnected
from the vehicle circuit.
Note:
While the engine is running the
battery terminal clamps must not
be loosened or detached as other­
wise the alternator and other elec­
tronic units would be damaged.
