Removal Procedure
- Remove the generator. Refer to Generator Replacement (1.2L SOHC) .
- Mark the generator housing for assembly.
- Remove the front bracket and rear bracket.
- Remove the generator through-bolts.
- Pry the front housing downwards using a screwdriver.
- Separate the front housing and rear housing.
- Cover the rotor with the cloth.
- Place the pulley upwards and carefully vise the rotor.
- Remove the pulley nut.
- Remove the pulley.
- Remove the collar (large).
- Remove the rotor from the front housing.
- Remove the collar (small) from the rotor shaft.
- Remove the support plate screws.
- Remove the support plate.
- Remove the front bearing using a press.
- Remove the battery position terminal nut.
- Remove the battery positive terminal washer.
- Remove the stator assembly from the rear housing.
- Remove the rectifier screws.
- Remove the brush holder and regulator assembly screws.
- Remove the stator assembly with the rectifier/brush holder/regulator.
- Remove the rectifier/brush holder/regulator connections.
- Remove the stator and rectifier connections.
- Test the rotor for an open circuit by using the ohmmeter. Replace the rotor if necessary.
- Test the rotor for a shorted circuit. The measured resistance should be around 2.9 ohms. Replace the rotor if not within the specification.
- Test the stator for an open circuit by using the ohmmeter. Replace the stator if necessary.
- Test the stator for a grounded circuit by using an ohmmeter. Replace the stator if necessary.
- Inspect the rectifier, positive rectifier test.
- Inspect for an open circuit at the stator coil lead terminals using an ohmmeter.
- Replace the rectifier if necessary.
- Inspect the rectifier, negative rectifier test.
- Inspect for an open circuit at the stator coil lead terminals using an ohmmeter.
- Replace the rectifier if necessary.
- Inspect trio diodes for an open circuit using an ohmmeter. Replace the trio diodes if necessary.
- Inspect the brushes for wear.
- If the brush wear exceeds the specified value (A), replace the brush. Brush Wear: Standard 18.5 mm (0.73 in) Limit 13.5 mm (0.53 in).
NOTE:
If the stator connections are welded in, use just enough heat to melt the lead. Avoid using to much heat as it can damage the diodes.
