The manufacturer of gas generator set believes that this problem may be caused by the damage of fuse or rectifier diode. When the fuse is blown out, the charger power indicator does not light up; After the rectifier diode is damaged, the power indicator of the charger is on, but there is no DC output.

1、充電機變壓器被燒壞。

1. The charger transformer is burnt out.

2、充電機上的二極管被燒壞。

2. The diode on the charger is burnt out.

3、充電機的充電電流表損壞。

3. The charging ammeter of the charger is damaged.

4、充電機的保險絲被燒壞。

4. The fuse of the charger is burnt out.

排除故障的方法就是：斷開充電機與蓄電池的連接線，用萬用表直流電壓擋（50V）測試充電機兩個輸出接線柱間的電壓，注意紅表筆接充電機的正極，黑表筆接負極，發現無電壓輸出。

The troubleshooting method is: disconnect the connecting wire between the charger and the battery, test the voltage between the two output terminals of the charger with the DC voltage gear (50V) of the multimeter, and pay attention to the red probe connected to the positive pole of the charger and the black probe connected to the negative pole. It is found that there is no voltage output.

拆下充電機外殼，對充電保險芯子進行檢查，發現60A的保險芯子燒壞。更換后，充電機恢復正常充電，故障即被排除。

Remove the charger shell and check the charging fuse core. It is found that the fuse core of 60A is burnt out. After replacement, the charger will resume normal charging and the fault will be eliminated.
