ГЕНЕРАТОР - ПРОВЕРКА
| 1. INSPECT GENERATOR ROTOR ASSEMBLY |
Check the generator rotor for an open circuit.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Slip ring - Slip ring 20°C (68°F) 2.1 to 2.5 Ω
| *1 | Slip Ring |
If the result is not as specified, replace the generator rotor assembly.
Check if the generator rotor is grounded.
Measure the resistance according to the value(s) in the table below.
- Standard Condition:
Tester Connection Condition Specified Condition Slip ring - Rotor core Always 10 kΩ or higher
| *1 | Slip Ring |
| *2 | Rotor Core |
If the result is not as specified, replace the generator rotor assembly.
Check that the slip rings are not rough or scored.
If they are rough or scored, replace the generator rotor assembly.
Using a vernier caliper, measure the slip ring diameter.
- Standard diameter:
- 14.2 to 14.4 mm (0.559 to 0.567 in.)
- Minimum diameter:
- 14.0 mm (0.551 in.)
| *1 | Diameter |
If the diameter is less than the minimum, replace the generator rotor assembly.
Inspect the bearing.
Check that the bearing is not rough or worn.
If necessary, replace the generator rotor assembly.
| 2. INSPECT DRIVE END FRAME |
Check the stator for an open circuit.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Coil lead - Coil lead Always Below 1 Ω
| *1 | Coil Lead |
If the result is not as specified, replace the generator assembly.
Check the stator for a short circuit.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Coil lead - Drive end frame Always 10 kΩ or higher
| *1 | Coil Lead |
| *2 | Drive End Frame |
If the result is not as specified, replace the generator assembly.
Inspect the bearing.
Check that the bearing is not rough or worn.
If necessary, replace the generator assembly.
| 3. INSPECT BRUSH HOLDER |
Using a vernier caliper, measure the exposed brush length.
- Standard exposed length:
- 9.5 to 11.5 mm (0.374 to 0.453 in.)
- Minimum exposed length:
- 4.5 mm (0.177 in.)
| *1 | Length |
If the exposed length is less than the minimum, replace the brush holder.
| 4. INSPECT GENERATOR HOLDER WITH RECTIFIER |
Check the positive terminal of the rectifier.
| *1 | Positive (+) Terminal |
| *2 | Rectifier Terminal |
Using an ohmmeter, connect one tester probe to the positive (+) terminal and the other to each rectifier terminal.
Reverse the polarity of the tester probes and repeat the step above.
Check that one polarity shows a resistance of below 1 Ω and the other shows a resistance of 10 kΩ or higher.
If the result is not as specified, replace the generator holder with rectifier.
Check the negative terminal of the rectifier.
| *1 | Negative (-) Terminal |
Using an ohmmeter, connect one tester probe to the negative (-) terminal and the other to each rectifier terminal.
Reverse the polarity of the tester probes and repeat the step above.
Check that one polarity shows a resistance of below 1 Ω and the other shows a resistance of 10 kΩ or higher.
If the result is not as specified, replace the generator holder with rectifier.
| 5. INSPECT GENERATOR REGULATOR ASSEMBLY |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Terminal F - Terminal B Always Below 1 Ω or higher than 10 kΩ
| *1 | Terminal F |
| *2 | Terminal B |
If the result is not as specified, replace the generator regulator assembly.
- УКАЗАНИЕ:
- When the ohmmeter leads are initially touched to the regulator, one of the above values is output. When the leads are reversed, the reading changes to the other value.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition Terminal F - Terminal E Always Below 1 Ω or higher than 10 kΩ
| *1 | Terminal F |
| *2 | Terminal E |
If the result is not as specified, replace the generator regulator assembly.
- УКАЗАНИЕ:
- When the ohmmeter leads are initially touched to the regulator, one of the above values is output. When the leads are reversed, the reading changes to the other value.
