(2) Upon completion of the test, set the engine speed at idle and
turn off the ignition switch.
(3) Disconnect the battery ground cable.
(4) Remove the test voltmeter and ammeter and the engine ta-
chometer.
(5) Connect the alternator output wire to the alternator “B” ter-
minal.
(6) Connect the battery ground cable.

Caution
White
I Blue
I Care should be taken in the event battery case is cracked
or leaking to protect hands from the electrolyte. A suit-
able pair of rubber gloves (not the household type) should
be worn when removing battery by hand.
3. Inspect battery carrier for damage caused by loss of acid from
battery. If acid damage is present, it will be necessary to clean
area with a solution of clean warm water and baking soda.
Scrub area with a stiff bristle brush and wipe off with a cloth
moistened with ammonia or baking soda in water.
4. Clean top of battery with same solutions as described in Step
(3).
INSPECTION OF BATTERY NOBEIBA
VISUAL INSPECTION OF BATTERY (1)
The batten/ contains a visual test indicator which gives blue signal
when an adequate charge level exists, and white signal when
charging is required.
VISUAL INSPECTION OF BAlTERY (2)
Make sure ignition switch is in Off position and all battery feed
accessories are Off.
1. Disconnect ground cable from battery before disconnecting
(+) cable.
5. Inspect battery case and cover for cracks. If cracks are
present, battery must be replaced.
6. Clean the battery post with a suitable battery post cleaning
tool.
7. Clean the inside surfaces of the terminal clamps with a suit-
able battery terminal cleaning tool. Replace damaged or frayed
cables and broken terminals clamps.
8. Install the battery in vehicle.
9. Connect (+) and (-) cables to battery in the order of mention.
10. Tighten the clamp nut securely.

8-82 CHARGING SYSTEM - Service Adjustment Procedures
BATTERY CHARGING NOEEICDZ
Caution
When batteries are being charged, an explosive gas forms
beneath the cover of each cell. Do not smoke near batteries
on charge or which have recently been charged. Do not
break live circuits at the terminals of the batteries on
charge. A spark will occur where the live circuit is broken.
Keep all open flames away from the battery.
Battery electrolyte temperature may temporarily be allowed to
rise to 55°C (131°F). Increase of electrolyte temperature above
55°C (131°F) is harmful to the battery, causing deformation of
battery cell, decrease in life of battery, etc.
CHARGE RATE
If the test indicator is white, the battery should be charged as
outlined below.
When the dot appears or when maximum charge shown
below is reached, charging should be stopped.
NOTE
If the indicator does not turn to blue even after the battery is
charged, the battery should be replaced; do not overcharge.
