CH02U–01 Z11577 Except Maintenance–Free Battery Z11556 Maintenance–Free Battery Voltmeter –CHARGING (5S–FE) CHARGING SYSTEM CH–1 1748AuthorĂ: DateĂ: CHARGING SYSTEM ON–VEHICLE INSPECTION CAUTION: z Check that the battery cables are connected to the correct terminals. z Disconnect the battery cables when the battery is giv- en a quick charge. z Do not perform tests with a high voltage insulation re- sistance tester. z Never disconnect the battery while the engine is run- ning. 1. CHECK BATTERY ELECTROLYTE LEVEL Check the electrolyte quantity of each cell. Maintenance–Free Battery: If under the lower level, replace the battery (or add distilled wa- ter if possible). Check the charging system. Except Maintenance–Free Battery: If under the lower level, add distilled water. 2. Except Maintenance–Free Battery: CHECK BATTERY SPECIFIC GRAVITY Check the specific gravity of each cell. Standard specific gravity: 1.25 – 1.29 at 20°C (68°F) If the specific gravity is less than specification, charge the bat- tery. 3. Maintenance–Free Battery: CHECK BATTERY VOLTAGE (a) After having driven the vehicle and in the case that 20 minutes have not passed after having stopped the en- gine, turn the ignition switch ON and turn on the electrical system (headlight, blower motor, rear defogger etc.) for 60 seconds to remove the surface charge. (b) Turn the ignition switch OFF and turn off the electrical sys- tems. (c) Measure the battery voltage between the negative (–) and positive (+) terminals of the battery. Standard voltage: 12.5 – 12.9 V at 20°C (68°F) If the voltage is less than specification, charge the battery.

CHECK BATTERY TERMINALS, FUSIBLE LINK AND FUSES (a) Check that the battery terminals are not loose or cor- roded. If the terminals are corroded, clean the terminals. (b) Check the fusible link, H–fuses, M–fuse and fuses for continuity. 5. INSPECT DRIVE BELTS (a) Visually check the drive belt for excessive wear, frayed cords etc. If any defect has been found, replace the drive belt. HINT: Cracks on the rib side of a drive belt are considered acceptable. If the drive belt has chunks missing from the ribs, it should be replaced. (b) Using a belt tension gauge, measure the belt tension. Belt tension gauge: DENSO BTG–20 (95506–00020) Borroughs No. BT–33–73F Drive belt tension: w/ A/C New belt Used belt 165 ± 25 lbf 110 ± 10 lbf w/o A/C New belt Used belt 125 ± 25 lbf 95 ± 20 lbf If the belt tension is not as specified, adjust it. HINT: z ”New belt” refers to a belt which has been used less than 5 minutes on a running engine. z ”Used belt” refers to a belt which has been used on a run- ning engine for 5 minutes or more. z After installing a belt, check that it fits properly in the ribbed grooves. z Check with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley.

(b) Turn off all accessories. (c) Turn the ignition switch ”ON”. Check that the charge warn- ing light is lit. (d) Start the engine. Check that the light goes off. If the light does not go off as specified, troubleshoot the charge light circuit. 8. INSPECT CHARGING CIRCUIT WITHOUT LOAD HINT: If a battery/generator tester is available, connect the tester to the charging circuit as per manufacturer’s instructions. (a) If a tester is not available, connect a voltmeter and amme- ter to the charging circuit as follows: (1) Disconnect the wire from terminal B of the genera- tor, and connect it to the negative (–) tester probe of the ammeter. (2) Connect the positive (+) tester probe of the amme- ter to terminal B of the generator. (3) Connect the positive (+) tester probe of the voltme- ter to terminal B of the generator. (4) Ground the negative (–) tester probe of the voltme- ter. (b) Check the charging circuit as follows: With the engine running from idling to 2,000 rpm, check the reading on the ammeter and voltmeter. Standard amperage: 10 A or less Standard voltage: 13.5 – 15.1 V If the voltmeter reading is more than standard voltage, replace the voltage regulator. P14433 Terminal F CH–4 –CHARGING (5S–FE) CHARGING SYSTEM 1751AuthorĂ: DateĂ: If the voltmeter reading is less than standard voltage, check the voltage regulator and generator as follows: z With terminal F grounded, start the engine and check the voltmeter reading of terminal B. z If the voltmeter reading is more than standard volt- age, replace the voltage regulator. z If the voltmeter reading is less than standard volt- age, check the generator. 9. INSPECT CHARGING CIRCUIT WITH LOAD (a) With the engine running at 2,000 rpm, turn on the high beam headlights and place the heater blower switch at ”HI”. (b) Check the reading on the ammeter. Standard amperage: 30 A or more If the ammeter reading is less than the standard amperage, re- pair the generator. HINT: If the battery is fully charged, the indication will sometimes be less than standard amperage.
