Reasons for generator set not charging:

1. Loose or detached wire joints, damaged wire sheaths, and short circuits caused by grounding;

2. Fan pulley too loose or oil slipping;

3. The commutator of the generator is worn, burned or contaminated with oil, the magnetic field coil is open or short circuited, the armature coil is open or short circuited, there is a short circuit between the rectifier pieces, and the insulation carbon brush holder is grounded;

4. The contacts of the regulator or throttle are burnt or contaminated, the balance resistance is broken, the bridge line of the regulator is burned out, the spring tension of the regulator is weak, the air gap is too small, the limit voltage of the regulator is adjusted too low, the closing voltage of the circuit breaker is too high, or the parallel coil is broken.

Generator set fault inspection and troubleshooting:

When it is found that the battery is not charging, first check whether the wiring is loose and whether the fan belt is too loose or slipping. If it is normal, then check in the following order.

1. Use a screwdriver to connect the regulator armature to the magnetic field terminal. If charged, the fault is usually a burnt out contact or balance resistor of the regulator or throttle. If not charged, proceed to the next step of inspection.

2. Use a screwdriver to connect the generator armature to the magnetic field terminal. If charging occurs, the fault is a broken wire between the generator magnetic field terminal and the regulator magnetic field terminal. If there is still no power generation, further inspection is needed.

3. Use a screwdriver to make contact between the armature connection post and the housing and scrape the fire. If there is a fire, then use a screwdriver to connect the circuit breaker and throttle connection post on the regulator. If charging, the fault is that the circuit breaker contact is burned, the contact is poor, or the wire is loose; If not charged, the fault is an open circuit in the charging circuit. If a screwdriver is used to scrape the contact between the armature connection post and the casing, and there is no fire, the fault is inside the generator. Further inspection of the generator is necessary.

4. Check if the commutator is too dirty, clean it if necessary, and then try again. If it is not dirty, press the two carbon brushes tightly with your fingers. If it is charged, the fault is insufficient spring elasticity or excessive wear of the carbon brushes. If the battery still does not charge, check whether the armature terminal is grounded or the wire is open, and whether the negative carbon brush holder is grounded; If all of the above are good, check whether the magnetic field coil or terminal is grounded or open circuit.
