GENERATOR INSPECTION [MZR-CD (RF Turbo)]

BME011718300W06

## Generator Warning Light

1. Verify that the battery is fully charged.

  • Charge if necessary.

2. Verify that the drive belt deflection/tension is correct. (See DRIVE BELT INSPECTION [MZR-CD (RF Turbo)].)

  • Replace if necessary.

3. Turn the engine switch to the ON position and verify that the generator warning light turns on.

  • If not, inspect generator warning light, wiring harnesses between the battery, generator warning light, and generator terminal L.

4. Verify that the generator warning light goes out after the engine is started.

  • If not, inspect the generator.

## Generator

### Voltage

1. Verify that the battery is fully charged.

  • Charge if necessary.

2. Inspect the drive belt deflection/tension. (See DRIVE BELT INSPECTION [MZR-CD (RF Turbo)].)

  • Replace if necessary.

3. Turn off all electrical loads.

4. Turn the engine switch to start the engine and verify that the generator rotates smoothly without any noise while the engine is running.

5. Measure the voltage at the terminals shown in the table.

  • If there is any malfunction, repair or replace the generator if necessary.

Standard voltage

Terminal | Engine switch ON (V) | Idle (V) [20 °C {68 °F}]
--- | --- | ---
B | B+ | 14.1-14.7
L | Approx. 1 | 14.1-14.7
S | B+ | 14.1-14.7

## Current

1. Verify that the battery is fully charged.

  • Charge if necessary.

2. Verify that the drive belt deflection/tension is correct. (See DRIVE BELT INSPECTION [MZR-CD (RF Turbo)].)

  • Replace if necessary.

3. Disconnect the negative battery cable.

4. Connect an ammeter, capable of reading 120 A or more, between generator terminal B and the wiring harness.

5. Connect the negative battery cable.

6. Turn off all electrical loads.

7. Start the engine and increase the engine speed to 2,000-2,500 rpm.

8. Turn the following electrical loads on and verify that the current reading increases.

  (1) Headlights
  (2) Blower motor
  (3) Rear window defroster

  • If generator terminal B current will not increase, repair or replace the generator if necessary.

  Note

  • Current required for generating power varies with electrical loads applied.

### Standard current (Reference)

Measuring conditions

  Room temperature: 20 °C {68 °F}
  Voltage: 13.5 V
  Engine hot

Engine speed (rpm) | Terminal B current (A)
--- | ---
1,000 | 0*-80
2,000 | 0*-90

  * :
Lower limit of current must be more than 0 A.
