IC Regulator Assembly

Connect a variable resistor, two 12V batteries, a fixed
resistor, and a voltmeter to the IC regulator as shown in
illustration.

a. Measuring equipment specifications
1. Fixed resistor (R1) : 10 Ohms /3W
2. Variable resistor (Rv) : 0-300 Ohms/12W
3. Batteries (BAT1, BAT2) : 12V (2 Batteries)
4. DC voltmeter : 0-50V/0.5 steps (4 Check points)
b. Measuring procedure
1. Measure the voltage “V1” across the first battery

(BAT1). If the reading is between 10 and 13 volts,
the battery is normal.

2. Measure the voltage “V3” across both the batteries

(BAT1, BAT2). If the reading is between 20 and 26
bolts, the batteries are normal.

3. Gradually increase the resistance of the variable

resistor from zero. Measure the voltage “V2” (the
voltage across the F and E terminals).

Check to see that the voltage across “V1” changes at
this time. If there is no change, the voltage regulator
is faulty and must be replaced.

4. Measure the voltage at “V4” (the voltage across the

variable resistor center tap and terminal E with the
variable resistor resistance held constant). The
measure voltage should be within the specified
(14.4

0.3 volts) limits. If it is not, the regulator must

be replaced.

Reassembly

To reassemble, follow the disassembly steps in the
reverse order, noting the following points:

NOTE:

Never make battery connections with polarities
reversed, or battery will be shorted via the diodes.
This will cause damage to the diodes.

Do not connect generator B terminal to ground; it is
connected directly to the battery.
This cable will burn if it is connected to ground.

Make sure to disconnect the positive (+) terminal of
the battery when quick-charging battery .
Diodes may be damaged due to abnormal pulse
voltage generated bye the quick charger.

When reassembling the front section to rear section,
insert a stiff wire into hole in the rear face of the rear
cover from the outboard side to support the brush in
raised position, then insert the front section to which
rotor is assembled.

Reassemble parts carefully to be sure they fit into
their original position, paying attention to the
insulated portions.

Wipe insulating tubes, washers and plates clean and
install them in position carefully to avoid getting oil or
grease on them.

STARTING AND CHARGING SYSTEM

1. Using a press with a socket wrench attached,

reassemble rotor and rear end cover assembly in the
front cover.

066RS022

2. Install pulley on the rotor.

Secure the pulley directly in the vise between two
copper plates, and tighten nut to the specified torque.

Torque: 111 N·m (82 lb ft)

066RS010

Bench Test

Conduct a bench test of the generator.

066RS023

Preparation

Remove generator from the vehicle (see “Generator
removal”).

1. Secure generator to the bench test equipment and

connect wires.
Terminal “IG” for energization
Terminal “L” for neutral (warning lamp)
Terminal “B” for output

2. Conduct the generator characteristic test.

Characteristics of generator are shown in illustration.
Repair or replace the generator if its outputs are
abnormal.
