ELECTRICAL SYSTEM CHARGING SYSTEM DESCRIPTION When the engine is started the AC generator runs and produces an output current This current is full wave rectified by a rectifier from which the current runs to the battery and the load If the output power generated by the AC generator rises above the battery and load currents the battery terminal voltage is raised so that at or over the specific voltage applied via the rectifier diode the zener diode DZ is switched on in response to the voltage presented by dividing resistor Ra and Rb Thus a gate signal is supplied to the thyristor SCR to short the AC terminal of the AC generator In case of low speed or large load neither SCR1 nor SCR2 starts operating and in case of high speed or small load both SCR1 and SCR2 operate to cover a wider control range METHOD OF TESTING RECTIFIER REGULATOR AND ALTERNATOR Before testing them check the battery voltage If it is less than 12 5V recharge the battery If the battery is discharged or broken it is not possible to check the rec tifier regulator and alternator to determine whether or not they are normal Set all switches in the OFF position and remove the headlamp fuse from the fuse box Connect the 4 lead of the tester to the terminal of the battery and the lead of the tester to the terminal of the battery Run the engine at 5 000 rpm and read the tester If the tester reads 14 to 15 5V they are normal If the tester reads more than 15 5V the regulator is faulty The regulator is a non disassembly type so it must be replaced if faulty If the tester reads less than 14V the rec tifier or the regulator or the alternator is faulty 11 5
