ELECTRICAL SYSTEM INSPECTION OF CHARGING SYSTEM COMPONENTS Rectifier A total of 6 semi conductor elements are con nected as shown for full wave rectification They are encapsulated into a mold and con tained in a compact case Each element is con ductive in the forward direction and non conductive in the reverse direction Check each ele ment for this property of directionality with a tester as follows 1 Undo all the terminal connections on the rectifier disconnecting the lead wires com ing from the alternator YELLOW WHITE RED and WHITE BLUE from the battery RED and from ground BLACK WHITE 2 Put the minus probe pin of the tester on to ground terminal BLACK WHITE and the positive pin on to YELLOW WHITE RED and WHITE BLUE se quentially in that order The tester should indicate continuity for each Repeat this process with minus pin and plus pin swapped the tester should not indicate continuity i i i WHITE RED YELLOW 3 You have just checked the three rectifier elements Check the other three in the same way by putting one of the probe pins on to the output terminal RED If any one of the elements is found to be non conductive in the forward direction or conductive in the reverse direction replace the rectifier unit L H hng 2 i c nt a PI ppc unit uht nl lo thik or UW ilf W U nt i K i littet 4 Hi1 andd rwe 0 incline i H PL n l U kid dni likihd or MilsflllM d tkunm ed pild I RID the ftt JhP it lmn t kt i ht lb It should be borne in mind that when the circuit tester is used for checking ohmic resistance or continuity its internally contained battery becomes connected to the probe pins plus polarity appears on negative pin and minus polarity on positive pin WHITE BLUE T T T BLACK WHITE Fig 11 14 Alternator Disconnect the yellow and white blue leads from the regulator 1 Disconnect the white blue lead from the alternator Connect the terminal of the tester to the red and its terminal to the terminal of the battery The coils and are good if the tester reads 16 5V or more at 5 000 rpm Fig 11 15 Fig 11 16 11 6
