TESTING

ON-VEHICLE TEST

CAUTION: DO NOT short across any alternator terminals or run vehicle
with any wires disconnected. Battery must be fully charged
for tests to be accurate.

Output Test
1) With ignition switch off, check voltage at "R" terminal
and "L" terminal. Reading at both terminals should be 0 volts. If not
0 volts, alternator is defective.
2) Turn ignition switch on but do not start engine. Voltage
at "L" should be 1-3 volts. If voltage is 0, alternator and regulator
are defective.
3) If voltage at "L" is close to battery voltage with
ignition on, short circuit the "F" terminal to rear alternator
housing. See Fig. 1.

Fig. 1: Alternator "F" Terminal Location
Terminal is located .8" (20 mm) below the hole.

4) Read the voltage at "L" with "F" terminal shorted. If
voltage is lower than battery voltage, regulator is defective. If
voltage is close to battery voltage, alternator is defective.
5) With ignition switch off and battery ground cable
disconnected, connect ammeter between alternator terminal "B" and
cable. Connect voltmeter between "B" (+) terminal and ground. See
Fig. 2.

6) Start engine and accelerate to 2000-3000 RPM. Turn on all
lights and check ammeter for output.
