ELECTRICAL 31 3.8 Pulley and pulley Protective cap Assembly: Insert the solid pulley in to the rotor shaft, use the assembly tool as described in point 1.1. Hold the alternator pulley by hand or with a pulley holder, using the serration tool overrunning alternator pulley can be screwed into the alternator shaft. Protective cap can be assembled by hand pressing on to the pulley. NOTE It is not permitted to operate the over running alternator pulley without protective cap. REFITTMENT: 1.Locate the alternator on its mounting bracket and fit the three mounting bolts with specified tightening torque. 2.Fit the Alternator belt. 3.Connect the electrical connection. ALTERNATOR TESTING PROCEDURES VOLTAGE DROP TEST OF ALTERNATOR OUTPUT WIRE This test determines whether or not the wiring between the alternator "B" terminal and the battery (+) terminal is good by the voltage drop method. 1. Turn the ignition switch to "OFF". 2. Disconnect the output wire from the alternator "B" terminal. Connect the (+) lead wire of ammeter to the "B" terminal of alternator and the (-) lead wire of am- meter to the output wire. Connect the (+) lead wire of voltmeter to the "B" terminal of alternator and the (-) lead wire of voltmeter to the (+) terminal of battery. TEST 1. Start the engine. 2. Turn on the headlamps and blower motor, and set the engine speed until the ammeter indicates 20A. And then, read the voltmeter at this time. RESULT 1. The voltmeter may indicate the standard value. Standard value: 0.2V max. 2. If the value of the voltmeter is higher than expected (above 0.2V max.), poor wiring is suspected. In this case check the wiring from the alternator "B" terminal to the battery (+) terminal. Check for loose connections, color change due to an over-heated harness, etc. Correct them before testing again. 3. Upon completion of the test, set the engine speed at idle. Turn off the headlamps, blower motor and the ignition switch. OUTPUT CURRENT TEST This test determines whether or not the alternator gives an output current that is equivalent to the normal output. PREPARATION 1. Prior to the test, check the following items and correct as necessary. Check the battery installed in the vehicle to ensure that it is good condition. The battery checking method is
