If the voltage is not within the standard value,
there is a malfunction of the voltage regulator or of
the alternator.
14.After the test, lower the engine speed to the idle speed.
15.Turn the ignition switch to the "LOCK" (OFF) position.
16.Remove the tachometer or the M.U.T.-II/III.
17.Disconnect the negative battery cable.
18.Disconnect the ammeter and voltmeter.
19.Connect the alternator output wire to the alternator "B" terminal.
20.Remove the special tool, and return the connector
to the original condition.
21.Connect the negative battery cable.

CAUTION
Do not insert the screwdriver blades too deep.
Doing so could damage the stator coil.
Insert the blades of screwdrivers between the front
bracket assembly and stator core, and pry and sepa

CAUTION
•Use a 180 − 250 W soldering iron, and finish
unsoldering within four seconds. Diodes will
be damaged by heat if unsoldering time is too
long.
•Avoid applying undue force to the diode
leads.
1. Unsolder the stator leads from the main diode of the rectifier assembly when the stator is removed.
2. When removing the rectifier assembly from the regulator assembly, undo the soldered points on
the rectifier assembly.
