Gravity Conversion; Battery Terminal Connections - Isuzu 4BG1 Instruction Manual

NOTICE: The battery electrolyte is dilute sulfuric acid. So, be careful
r
.
not to stain your body and clothes with it. If stained, rinse
portion in clean water.
Gravity conversion
The specified electrolyte temperature for the gravity measure-
ment is 20°C (68°F).
Measure the electrolyte temperature and do the conversion in
accordance with the following formula when the temperature
does not fall to the specified temperature.
30 = St + 0.0007 (t -20)
S20 ; gravity at 20°C
St ; gravity measured
t ; electrolyte temperature whe measured
Battery terminal connections
Periodically, check. the battery terminals for loose connection
and corrosion.
For the check interval, follow the machine manufacturer' s
standard. Loose connection will cause hard engine starting or
deficient battery charging.
If the terminals are excessively corroded, disconnect the battery
cables and polish them with a wire brush or sandpaper.
Never reverse the "+" and "-" terminals when reconnecting the
cables. Even a short period of reverse connection could damage
the electrical parts.
