(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.
ll3Y1848 2. Remove battery from vehicle.
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.

IGNITION SYSTEM-Service Adjustment Procedures 8-113
SPARK TEST - ENGINE CANNOT BE CRANKED
If spark test is performed by cranking while the catalyst is hot,
unburned gas will be supplied to the catalyst, and this is not de-
sirable to the catalyst.
For this reason, use the following methods which allow spark test
to be performed without cranking.
1. Remove the distributor cap.
2. Check signal rotor position in relation to the pick-up. If it is not
the position shown in the illustration, turn the crankshaft man-
ually so that the projection of the signal rotor is moved away
from the center part of the pick-up. In order words, the signal
rotor should be positioned so that current can flow to the
ignition coil.
3. Disconnect the high tension cable from the center tower of
the distributor cap, and hold the end of the cable about 5 - 10
mm (.2 - .4 in.) away from the cylinder block of the engine.
4. Turn the ignition switch to “ON”. Then, when a piece of metal
(the tip of a screwdriver for instance) is inserted into the de-
tection coil of the pick-up and then moved away, a spak can be
generated.
