Checking 

 

 

 

Risk of explosion caused 
by oxyhydrogen gas. Risk 
of poisoning and caustic 
burns caused by 
swallowing battery acid. 
Risk of injury caused by 
burns to skin and eyes 
from battery acid or when 
handling damaged lead-
acid batteries

No fire, sparks, open flames 
or smoking. Wear acid-
resistant gloves, clothing 
and goggles. Only pour 
battery acid into suitable 
and appropriately marked 
containers.

Risk of accident caused 
by vehicle starting off by 
itself when engine is 
running. Risk of injury 
caused by contusions and 
burns during starting 
procedure or when 
working near the running 
engine

Secure vehicle to prevent it 
from moving by itself. 
Wear closed and snug-
fitting work clothes. 
Do not grasp hot or rotating 
parts.

Load battery (G1) with 
volt ampere tester (079) 
and check charging 
current of alternator (G2) 
with increased engine 
speed

 Vary load resistance 

long enough until the 
maximum load current is 
achieved; when this is 
done, the regulating voltage 
must not drop below 12.7 
V.
