Q: Diesel generator charging current is too small causes and solutions

A: This is usually due to the failure of individual silicon diode lead disconnected or sealing off the brush and slip ring caused by poor contact.

Reason:

1,belt slip

2, low voltage regulator

3, diesel generator magnetic field coil wire grounding or short to ground and other local

4, sealing off the diesel generator silicon diode lead off, the armature coils one phase or two-phase circuit

5, (there is dirt on the slip ring, carbon brushes wear too much, not enough spring pressure, etc.) brush and slip ring is bad, the contact resistance is large, so that the magnetizing current is reduced.

In response to this phenomenon should take the following solutions:

1 diesel generator contact with the slip ring brushes to conduct inspections and found no abnormalities

2, with a multimeter to measure DC voltage regulator block output voltage, output voltage is very low discovery

3, with a multimeter to measure DC voltage block generator output voltage, output voltage is found to 5V (adjust measurements to disconnect the connector and battery), which proved a failure in charging alternator

4, in the measurement of the diode, found four diodes burn. Replace the diode assembly for diesel generators, diesel generators and then start to 1300r/min, the charge meter on the dashboard display as 15A, described the diesel generator to charge properly.

The above is diesel generator charging current is too small causes and remedies, I hope everyone can help, if the other on diesel generator set technical problems, welcome to consult.
