Charging Voltage Inspection
•Check the battery condition(see Charging Condition Inspection).
•Warm up the engine to obtain actual alternator operating conditions.
•Remove the battery cover.
•Check that the ignition switch is turned off, and connect the hand tester to the battery terminals.
•Start the engine, and note the voltage readings at various engine speeds with the headlight turned on and then turned off. The readings should show nearly battery voltage when the engine speed is low, and, as the engine speed rises, the readings should also rise. But they must be kept under the specified voltage.
•Turn off the ignition switch to stop the engine, and disconnect the hand tester. If the charging voltage is kept between 13.9∼14.9 V, the charging system is considered to be working normally. If the charging voltage is much higher than the values specified in the table, the regulator/rectifier is defective or the regulator/rectifier leads are loose or open. If the charging voltage does not rise as the engine speed increases, then the regulator/rectifier is defective or the alternator output is insufficient for the loads. Check the alternator and regulator/rectifier to determine which part is defective.
Alternator Inspection
There are three types of alternator failures: short, open(wire burned out), or loss in rotor magnetism. A short or open in one of the coil wires will result in either a low output, or no output at all. A loss in rotor magnetism, which may be caused by dropping or hitting the alternator, by leaving it near an electromagnetic field, or just by aging, will result in low output.
