CHARGING THE BATTERY CAUTION: G Do not “quick charge” a fully discharged battery. G Keep the battery away from open flame while it is being charged. G When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark. If battery electrolyte temperature rises above 60°C (140°F), stop charging. Always charge battery at a temperature below 60°C (140°F).

Do not charge at more than 50 ampere rate. NOTE: The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi- cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps indicated above refer to initial charge rate.
If, after charging, the specific gravity of any two cells varies more than .050, the battery should be replaced.
Trouble Diagnoses with Battery/Starting/Charging System Tester CAUTION: When working with batteries, always wear appropriate eye protection. NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done as a set from start to finish. If battery surface charge is detected while testing, the tester will prompt you to turn on the headlights to remove the surface charge. If necessary, the tester will prompt you to determine if the battery temperature is above or below 0°C (32°F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to make the selection.

1. Turn off all loads on the vehicle electrical system. Clean or repair
as necessary.
2. Visually inspect the battery, battery terminals and cable ends
with ignition switch in “OFF” position. NOTE: The contact surface between the battery terminals, cable ends and tester leads must be clean for a valid test. A poor connec- tion will prevent testing and a “CHECK CONNECTION” mes- sage will appear during the test procedures. If this occurs, clean the battery post and terminals, reconnect them and restart the test.
3. Connect the red tester lead clamp to the positive battery termi-
nal, and the black to the negative terminal.
4. The tester will turn on automatically. Using the arrow keys, select “IN-VEHICLE” on the tester and then press the “ENTER” key.
5. Locate the battery type and rating stamped or written on the top
case of the battery to be tested. NOTE: The battery type and rating will have either of the following. CCA: Cold Cranking Amps (490 CCA, 550 CCA, etc.) JIS: Japanese Industrial Standard. Battery is stamped with a number such as: 80D26L: 80 (rank of output), D (physical size-depth), 26 (width in cm). The last character L (post configuration) is not input into the tester. The tester requires the rating for the battery be entered exactly as it is written or stamped on the battery. Do not attempt a CCA conversion for JIS stamped batteries. JIS must be input directly.
6. Using the arrow and “ENTER” keys alternately, select the battery type and rating.
NOTE: The tester lists five choices; CCA, JIS, IEC, DIN, and EN. Only use CCA or JIS.
7. Press “ENTER” to begin the test. Diagnosis results are dis- played on the tester. Refer to SC-8, "DIAGNOSTIC RESULT ITEM CHART" .

STARTING SYSTEM System Description M/T MODELS Power is supplied at all times:
through 40A fusible link (letter m , located in the fuse and fusible link box) to ignition switch terminal B.
With the ignition switch in the START position, power is supplied:
from ignition switch terminal ST to intelligent power distribution module engine room (IPDM E/R) terminal 4.
With the ignition switch in the ON or START position, power is supplied:
through 10A fuse [No. 12, located in the fuse block (J/B)] to IPDM E/R terminal 53.
When the clutch pedal is depressed, ground is supplied to IPDM E/R terminal 50 through the clutch interlock switch and body grounds E15 and E24. Provided that the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN lines, the IPDM E/R grounds the starter relay and power is supplied:
from terminal 3 of the IPDM E/R to terminal S of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates. In the event that the CAN communication line fails between the IPDM E/R and the BCM, the IPDM E/R will default to a starter relay request ON signal as long as the ignition switch remains in the START or ON position. A/T MODELS Power is supplied at all times:
through 40A fusible link (letter m , located in the fuse and fusible link box) to ignition switch terminal B.
With the ignition switch in the START position, power is supplied:
from ignition switch terminal ST to IPDM E/R terminal 4.
With the ignition switch in the ON or START position, power is supplied:
through 10A fuse [No. 12, located in the fuse block (J/B)] to park/neutral (PNP) switch terminal 1 (with 4 A/T) or terminal 5 (with 5 A/T).
With the selector lever in P or N position, power is supplied:
through PNP switch terminal 2 (with 4 A/T) or terminal 1 (with 5 A/T) to IPDM E/R terminal 53.
Provided the IPDM E/R receives a starter relay request ON signal from the BCM over the CAN lines, the IPDM E/R grounds the starter relay and power is supplied:
from terminal 3 of the IPDM E/R to terminal S of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block.

CHARGING SYSTEM
PFP:23100
CHARGING SYSTEM System Description The generator provides DC voltage to operate the vehicle's electrical system and to keep the battery charged. The voltage output is controlled by the IC regulator. Power is supplied at all times to generator terminal B through: 120A fusible link (letter a , located in the fusible link box). Power is supplied at all times to generator terminal S through: 10A fuse (No. 26, located in the fuse and fusible link box). Terminal B supplies power to charge the battery and operate the vehicle's electrical system. Output voltage is controlled by the IC regulator at terminal S detecting the input voltage. The charging circuit is protected by the 120A fusible link. The generator is grounded to the engine block. With the ignition switch in the ON or START position, power is supplied:
EKS008L6
through 10A fuse [No. 14, located in the fuse block (J/B)] to combination meter terminal 22 for the charge warning lamp.
Ground is supplied to terminal 14 of the combination meter through terminal L of the generator. With power and ground supplied, the charge warning lamp will illuminate. When the generator is providing sufficient volt- age with the engine running, the ground is opened and the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a fault is indicated.
