Generator — repair (Renault Espace I)

1. It is best to leave the repair and testing of the generator to specialists, as this requires special devices and test benches. Incorrect connection of measuring or testing devices can lead to immediate burning of the rectifier diodes.

2. Generator bearing grease is designed for a long time and does not require regular replacement. After a long period of operation, check the brushes and replace them if necessary. Please note the following instructions:

3. If the battery charge indicator lamp does not light when the ignition is turned on, check whether the lamp housing is damaged. To check, you can briefly install a 6.3 mm connector in connection with the ground. The lamp should light. If not, the following may be the reasons: the drive belt is torn, the cable in the charging circuit is damaged, the generator or voltage regulator is damaged.

4. If the test lamp is functioning, but the battery is constantly losing charge, check the regulator voltage with a voltmeter.

5. Place a voltmeter on the battery terminals and measure the voltage.

6. Start the engine and increase the speed until the voltmeter readings stabilize. The readings should be 13.5 - 14.8 V.

7. Switch off as many power consumers as possible and read the voltmeter again. The readings should be within the specified value. If the readings are different, remove the generator and contact a car repair shop. The following damages are possible: a damaged diode, a break in the rotor winding, worn out sliding graphite contacts or dirty contact rings.
