Hey all, just went to plug my board into my 600W that’s been working perfectly since I bought it a few months ago but tonight it wouldn’t charge my board.
It’s got a green light on it that is usually solid when the charger is on but disconnected from a battery or the battery is fully charged. Instead, it was just constantly flickering.
I could hear an arc coming from inside the enclosure so I opened the top to see if I could see where the sound was coming from although unfortunately it wasn’t particularly obvious, although I have a feeling that the sound is coming from near the 240V-36V transformer. I tried turning all the lights off to see if I could see any sparking but still no luck.
On the odd occasion when I turn the charger on, the green LED with flicker for a little bit and then turn solid green and the arcing sound will stop so it certainly just seems like there’s a dodgy connection somewhere.
I’m waiting to hear back from the AliExpress seller but I would very much appreciate any input from anyone who’s a little more experienced with AC-DC power supplies Here’s a few photo’s of the internals along with a video of the noise:
