CHARGING SYSTEM
TESTING PROCEDURE
NOTE: First, ensure that battery is in good condition prior to performing the following testIf the battery is regularly discharged, check charging system fuse (30 amp) conditionVoltage Test Proceed as follows: Start engine Connect multimeter to battery postsSet multimeter to Vdc scale Bring engine to approximately 5500 RPMIf multimeter reads over 15 volts, voltage regulator rectifier is defectiveReplace itNOTE: Whatever the voltmeter type used (peak voltage or RMS), the voltage must not exceed 15 VA faulty voltage regulatorrectifier will allow voltage to exceed 15 as engine speed is increasedNOTE: If it is continually necessary to add distilled water to the battery, this indicates an over voltage situation, requiring replacement of the voltage regulatorrectifierIf, on the other hand, the battery will not stay charged, the problem can be any of the charging circuit componentsIf these all check good, you would be accurate in assuming the problem to be in the voltage regulatorrectifierIf there is no charging at the battery with the preceding voltage test, the following test can also be performedVoltage RegulatorRectifier Output Test Remove the charging system fuse no6 (30 amp)Connect the negative probe on engine and the positive probe in the charging system fuse location where the value is VdcThe obtained value in the other location should be 12 VdcNOTE: If the voltage regulatorrectifier is within the specification, the wiring harness between the voltage regulatorrectifier and battery is defectiveIf the voltage regulatorrectifier is out of specification and the stator test good, the voltage regulator rectifier is defectiveV00G01D
