Battery, checking<br />

Página 14 de 28<br />

27-19<br />

An insufficient electrolyte level allows the cell<br />

plates to dry, resulting in a loss of battery<br />

capacity (reduced output). If the cell plates are<br />

not completely submerged by electrolyte,<br />

(sulfuric acid/water mixture) corrosion will occur<br />

on the plates, plate bridges and cell connector.<br />

Optimum battery function is not possible under<br />

these conditions and battery failure results.<br />

If electrolyte level is too high, electrolyte (sulfuric<br />

acid/water mixture) may leak out and damage<br />

the surrounding area, i.e.: plenum and engine<br />

compartment.<br />

CAUTION!<br />

Before beginning repairs on the electrical<br />

system<br />

Switch off all electrical consumers.<br />

Switch ignition off and remove ignition<br />

key.<br />

- Check electrolyte level visually, either via charge<br />

indicator (if equipped) or from min./max.<br />

markings on battery housing.<br />

Electrolyte level reading from min./max. marking on<br />

battery housing -arrow-.<br />

Electrolyte level must be above the minimum<br />

marking or just reach the maximum marking.<br />

If no minimum and maximum markings are visible<br />

on the battery housing (either not molded-in or not<br />

visible due to installation location) or if the battery<br />

housing is black, the sealing plugs must be<br />

removed. Then determine electrolyte level by<br />

viewing inside the battery cells.<br />
