Inspection
Indicator sign (If equipped)
1. Check that the indicator is blue.
2. If the indicator is not blue, check if the electrolyte level lies
between the upper and lower lines.
3. If low, add distilled water, being careful not to overfill.
4. If the electrolyte level is acceptable and yet the indicator
is not blue, the battery must be recharged.
Specific gravity of electrolyte
Measure the specific gravity with a hydrometer.
Specification: 1.27-l .29 (at 20°C [66OF])
Note
l If the battery charge indicator is not blue when the
specific gravity is normal, the indicator could be
defective.

Terminal and cable
1. Check the tightness of the terminals to ensure good electri-
cal connections.
2. Check for corroded or frayed battery cables.
3. Check the rubber protector on the positive terminal for prop-
er coverage.
4. Clean the terminals if necessary, and coat them with grease.

Slow charging
It is not necessary to remove the vent caps to perform a slow
charge.
Quick charging
Remove the battery from the vehicle and remove the vent caps
to perform a quick charge.
Warning
l Before performing maintenance or recharging the
battery, turn off all accessories and stop the engine.
l The negative cable must be removed first and in-
stalled last.
l Set the battery in water when quick charging to pre-
vent overheating the battery.

Caution
l Be sure the battery connections are not reversed, because this will damage the rectifier.
l Do not use high-voltage testers such as a megger, because they will damage the rectifier.
l Remember that battery voltage is always applied to the alternator B terminal.
l Do not ground the L terminal while the engine is running.
l Do not start the engine while the connector is disconnected from the L and S terminals.
1. Remove in the order shown in the figure.
2. Inspect all parts and repair or replace as necessary
3. Install in the reverse order of removal.
