How to judge the generator battery charger does not charge?
Fault analysis: The generator set battery charger does not charge the fault is generally caused by the damage of the fuse or rectifier diode when the fuse is burned, the power indicator light of the charging machine is not bright; After the rectifier diode is damaged, the power indicator of the charger lights up, but there is no direct current output
Cause of failure:
1. The diode on the charging machine is burned out.
2. The charger transformer is burned out.
3. The charging ammeter of the charger is damaged.
4. The fuse of the charger is burned out.
The solution:
1. Disconnect the connection line between the charger and the battery
2. Test the voltage between the two output terminals of the charger with the DC voltage file (50V) of the multimeter (note that the red pen is connected to the positive terminal of the charger, and the black pen is connected to the negative terminal), and find that there is no voltage output
3. Remove the charger shell, stop checking the charging insurance core, and find that the 60A insurance core is burned out. After changing, the charger returns to normal charging, and the fault is swept away.
