(5) Disconnect the alternator output wire from the alternator “B”
terminal.

(6) Connect a DC ammeter (0 to 100 A) in series between the “B”
terminal and the disconnected output wire. Connect the (+I
lead of the ammeter to the “B” terminal and connect the (-1
lead wire to the disconnected output wire.
(7) Set the engine tachometer and connect the battery ground
cable.

Test

(1) Turn on the ignition switch and-check that the voltmeter indi-
cates the following value.

Voltage : Battery voltage

If it reads 0 V, there is an open circuit in the wire between the
alternator “S” terminal and the battery (+) or the fusible link
is blown.

(2) Start the engine. Keep all lights and accessories off.

(3) Run the engine at a speed of about 2500 rpm and read the
voltmeter when the alternator output current drops to 10 A or
less.

Result

(1) If the voltmeter reading agrees with the value listed in the
regulating voltage table below, the voltage regulator is func-
tioning correctly. If the reading is other than the standard
value, the voltage regulator or the alternator is faulty.
