COMBINATION

OPERATION When engine is stopped When the ignition switch is switched to the CN position, electricity flows from the L terminal, of the alternator to the field coil, and at the same time the charging warning light illuminates. When engine is being started/has started When the engine is started, charging voltage is applied to the L terminal of the alternator, with the result that the charging warning light is extinguished. In addition, because battery voltage is applied to the S terminal of the alternator, this battery voltage is monitored at the IC voltage regulator, thus switching ON and OFF the current to the field coil and thereby controlling the amount of generation by the alternator. Power is supplied to each load from the 6 terminal of the alternator. NOTE The alternator relay functions as a back-up for the flow of electricity to the field coil if there is a disconnection or damaged wiring of the charging warning light.

CHARGING SYSTEM - Service Adjustment Procedures


NOTE Use of a clamp type ammeter that can measure current without disconnecting the harness is preferred. The reason is that when checking a vehicle that has a low output current due to poor connection of the alternator B terminal, such poor connection is corrected as the B terminal is loosened and a test ammeter is connected in its place and as a result, causes for the trouble may not be determined. (5) Connect a digital voltmeter between the alternator B terminal and battery (+ 1 terminal. Connect the ( + ) lead wire of the voltmeter to the B terminal and the ( - 1 lead wire to the battery ( + 1 terminal. (6) Connect the battery ground cable. (7) Leave the hood open.

VOLTAGE DROP TEST OF ALTERNATOR OUTPUT WIRE This test judges whether or not the wiring (including the fusible link) between the alternator B terminal and the battery ( + 1 terminal is sound by the voltage drop method. Preparation (1) Turn the ignition switch to OFF. (2) Disconnect the battery ground cable. 13) Disconnect the alternator output lead from the alternator B terminal. (4) Connect a DC ammeter (0 to lOOA) in series to the B terminal and the disconnected output lead.

(2) If the voltmeter indicates a value that is larger than the standard value, poor wiring is suspected, in which case check the wiring from the alternator B terminal to fusible link to battery ( + 1 terminal. Check for loose connection, color change due to overheated harness, etc. and correct them before testing again.

CHARGING SYSTEM - Service Adjustment Procedures


OUTPUT CURRENT TEST This test judges whether or not the alternator gives an output current that is equivalent to the nominal output. Preparation (I 1 Prior to the test, check the following items and correct as necessary. (a) Check the battery installed in the vehicle to ensure that it is in sound state*. The battery checking method is described in BATTERY. NOTE The battery that is used to test the output current should be one that has been rather discharged. With a fully charged battery, the test may not be conducted correctly due to an insufficient load. (b) Check tension of the alternator drive belt. The belt tension check method is described in GROUP O-Maintenance Service.

(2) Turn off the ignition switch. (3) Disconnect the battery ground cable. (4) Disconnect the alternator output wire from the alternator B terminal. (5) Connect a DC ammeter (0 to lOOA) in series between the B terminal and the disconnected output wire. Connect the (+ 1 lead of the ammeter to the B terminal and connect the I- 1 lead wire to the disconnected output wire. NOTE Tighten each connection by bolt and nut securely as a heavy current will flow. Do not relay on clips. (6) Connect a voltmeter (0 to 2OV) between the B terminal and ground. Connect the ( f 1 lead wire to the alternator B terminal and (-1 lead wire to a sound ground. (7) Set the engine tachometer and connect the battery ground cable. (8) Leave the engine hood open.

(3) Set the headlight at high beam and the heater blower switch at HIGH, quickly increase the engine speed to 2,500 rpm and read the maximum output current value indicated by the ammeter. NOTE After the engine start up, the charging current quickly drops, therefore, above operation must be done quickly to read maximum current value correctly.

CHARGING SYSTEM - Service Adjustment Procedures


In such a case, keep the headlights on to cause discharge of the battery or use lights of another vehicle as a load to increase the electrical load. The nominal output current may not be obtained if the temperature of the alternator itself or ambient temperature is too high. In such a case, reduce the temperature before testing again. Upon completion of the output current test, lower the engine speed to the idle speed and turn off the ignition switch. Disconnect the battery ground cable. Remove the test ammeter and voltmeter and the engine tachometer. Connect the alternator output wire to the alternator B terminal. Connect the battery ground cable.

Therefore, the nominal output current may not be obtained if the vehicle electrical load at the time of test is small. REGULATED VOLTAGE TEST The purpose of this test is to check that the electronic voltage regulator controls the voltage correctly. Preparation (I) Prior to the test, check the following items and correct if necessary. (a) Check the battery installed on the vehicle to see that it is fully charged.

OPERATION
l

8-157

For models equipped with the M/T, the clutch pedal switch contact is switched OFF when the clutch pedal is depressed; when the ignition switch is then switched to the ST position, electricity flows to the starter relay and the starter motor, the contact (magnetic switch) of the starter is switched ON and the starter motor is activated. NOTE If the ignition switch is switched to the ST position without the clutch pedal being depressed, electricity flows to the starter relay (coil), the clutch switch (contacts) and to ground, with the result that the contacts of the starter relay are switched OFF, and, because the power to the starter motor is thereby interrupted, the starter motor is not activated.

For models equipped with the A/T, when the ignition switch is switched to the ST position while the selector lever is at the P or N position, the contact (magnetic switch) of the starter is switched ON and the starter motor is activated.

TROUBLESHOOTING HINTS
1. The starter motor does not operate at all. 0 Check the starter (coil). l Check for poor contact at the battery terminals. 2. The starter motor doesnt stop. l Check the starter (magnetic switch).
