CAUTION
While engine is running (alternator generating power), make sure that
Lterminal is not grounded. If Ltenninal is grounded, auxiliary diode
will be short-circuited and no voltage will be available at Lterminal, so
no power will be generated. Therefore, CHARGE lamp will remain lit.

TROUBLESHOOTING
TEST 5
With the engine stopped and the ignition switch in the “ON” position, measure
the voltage at the “F” terminal (for testing the alternator).
With the ignition switch in the “OFF” position, puIl the connector from the
alternator. Then, measure the voltage at the “L” terminal. If the voltage
battery voltage, the (t) diode is short-circuitd.
, CAUTION
When measuring the’ voltage of the “F” terminal (for testing), be
careful not to let the voltmeter probe contact the rear bracket. If
by chance it does contact it, there’s no problem if it’s immediately
pulled away.

Disconnect the wiring from the “B” terminal of the alternator, and
connect an ammeter (60 A or higher) between the wires and the terminal.
Start the engine. Then immediately increase the engine speed to 2,500 to 3,000
rpm and quickly read the maximum value shown by the ammeter. Note that
all loads on the electrical system should be “ON” when this test is made.
