A guy next door brought this hovering board power charger for repair and explained that the charger is completely dead. As he continued to explain that he heard a pup sound before it went into shut down.

As you can see in the photo, this charger is 42 DC volt rated at 2 amps. The idea of this charger is to get a green light on the stand by which mean the 42 DC volts are presents. Once it was plugged into the hovering board charging port, the light should switch to red indicating it was charging. Once the charging process is done, the charger should go back to the stand by light which is green. In my case here, the green light was not present and therefore it should be opened and checked out.

The moment I opened the charger, I saw that the fuse was not there which means it was blown off or someone tried to fix it and was not successful.

Since the fuse was gone, the only logical thing to do is to check the bridge rectifier.

After the cleaning of the charger and did some testing, I found out that the bridge rectifier was shorted and needed replacement.

In the photo above are the replacement of the bridge rectifier and a fuse. The fuse rating is 3.15 amp which I have plenty of in the shop. I checked for another shorted components and found none. I replace the bridge rectifier but I did not add the fuse yet, instead I added a light bulb to the fuse terminals (sorry forgot to take photo of) and powered on the device. The Light bulb stayed dim indicating all is well in this charger. The green light was on and steady.

I added the fuse in its place and powered on the charger and as expected, it was up and running.

    I suppose that after noticing the fuse had blown off on itself it was only because the diode bridge heavily shorted. And not because someone already had tried to fix it invain. And it is always a good thing having replacement fuses (and other parts) in stock for cases like this.
