Alternator's No-load Voltage
1. Disconnect the lead wire from the alternator.
2. Start the engine and measure the voltage generated by the
alternator.

Regulator (Standard Type)
1. The engine is started.
2. Measure the output voltage of the regulator with the voltmeter.
Output Voltage (1) - (2)
3. When the measurement is not the above table value, measure
the input voltage of the regulator with the voltmeter.
Input Voltage (3) - (4)
4. When the measurement is the above table value, the regulator
is failure. Exchange it.
When the input voltage of the regulator is out of
specification, check the generator.
