How to Handle BatteryNJSC0003CAUTION:
If it becomes necessary to start the engine with a booster
battery and jumper cables,
1) Use a 12-volt booster battery.
2) After connecting battery cables, ensure that they are
tightly clamped to battery terminals for good contact.
MEL040F
METHODS OF PREVENTING OVER-DISCHARGENJSC0003S01The following precautions must be taken to prevent over-discharg-
ing a battery.
+The battery surface (particularly its top) should always be kept
clean and dry.
+The terminal connections should be clean and tight.
+At every routine maintenance, check the electrolyte level.
This also applies to batteries designated as ªlow maintenanceº
and ªmaintenance-freeº.
MEL041F
+When the vehicle is not going to be used over a long period of
time, disconnect the negative battery terminal.
MEL042F
+Check the charge condition of the battery.
Periodically check the specific gravity of the electrolyte. Keep
a close check on charge condition to prevent over-discharge.
CHECKING ELECTROLYTE LEVELNJSC0003S02WARNING:
Do not allow battery fluid to come in contact with skin, eyes,
fabrics, or painted surfaces. After touching a battery, do not
touch or rub your eyes until you have thoroughly washed your
hands. If acid contacts eyes, skin or clothing, immediately
flush with water for 15 minutes and seek medical attention.

System DescriptionNJSC0004M/T MODELSNJSC0004S01Power is supplied at all times
+through 40A fusible link (letterB, located in the fuse and fusible link box)
+to ignition switch terminal 1.
With the ignition switch in START position, power is supplied
+from ignition switch terminal 5
+to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the engine
starts.
A/T MODELSNJSC0004S02Power is supplied at all times
+through 40A fusible link (letterB, located in the fuse and fusible link box)
+to ignition switch terminal 1.
With the ignition switch in the START position, power is supplied
+from ignition switch terminal 5
+to park/neutral position relay terminal 5.
With the ignition switch ON or START position, power is supplied
+through 10A fuse [No. 20, located in the fuse block (J/B)]
+to park/neutral position (PNP) relay terminal 1.
With the selector lever in the P or N position, ground is supplied
+to park/neutral position relay terminal 2 through the park/neutral position switch
+from body grounds, F9 and F10.
Then park/neutral position relay is energized and power is supplied
+from park/neutral position relay terminal 3
+to starter motor harness connector terminal 1.
The starter motor plunger closes and provides a closed circuit between the battery and starter motor. The
starter motor is grounded to the engine block. With power and ground supplied, cranking occurs and the engine
starts.
