Opel Frontera UBS. Manual - part 273

6D3–24 STARTING AND CHARGING SYSTEM

Stator Coil

1. Measure resistance between respective phases.
2. Measure insulation resistance between stator coil

and core with a mega–ohmmeter.
If less than standard, replace the coil.

066RS018

Brush

Measure the brush length.
If more than limit, replace the brush.

Standard: 10.mm (0.4134 in)

Limit: 8.4.mm (0.3307 in)

066RS019

Rectifier Assembly

Check for continuity across “P” and “E” in the 

×

 100W

range of multimeter.

066RW002

Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction.  In case of
continuity in both directions, replace the rectifier
assembly.

IC Regulator Assembly

Check for continuity across “B” and “F” in the 

×

 100W

range of multimeter.

066RS021

Change polarity, and make sure that there is continuity in
one direction, and not in the reverse direction.  In case of
continuity in both directions, replace the IC regulator
assembly.

Reassembly

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

6D3–25

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 (11.3 Kg·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.
