I have a 12s 2 amp charger and the led is just blinking red fast. Any ideas?
also when i check voltage at output terminals, only 28v are coming out
I’d toss it in the bin
I’d sell it as - new, still in box, never used, never tested
I had the same when I changed the polarity. Small spark, half od voltage and nothing you van do.
So i need to buy a new one?
What do u mean by reversing polarity. The wires connected to my dc port are correct. I checked them.
Unless your comfortable opening it up and finding whats wrong (preferably powered off since theres 230V in there…), yes you’ll need a new one
I conected the port wrong. I’m not saying that you did the same thing. Mine was blinking and I had half of the voltage and I bought new one and probably you’ll have to do the same.
I did open the charger up and i don’t see any burn marks or anything
Also which side am I supposed to plug in the first? Should I plug the dc side in first or plug it into the wall first?
Just cause there wasn’t a fire in it doesn’t mean something isnt broken. If u have a multimeter you can do some troubleshooting. Dont plug it in while you do it tho. 230VAC tickles the heart in a bad way. (had my hand in PC PSU once)
It shouldnt matter what you plug in first on a good charger.
Please be careful 110VAC can KILL you. If you don’t know what you are doing please leave it and buy a new one…
How can i troubleshoot it and see what happened?
Do you have any kind of training with electrical circuits? If not please buy a new one… @dg798
Not officially but is there anyway to troubleshoot it without plugging it in
Meassure between + and - on primary and secondary side to see if theres a short. (Ohm) Could also meassure the secondary sides voltage when turned on. (again, dont do this if you’re unfamiliar with electrical appliances, and always have it plugged in to a fast breaking fuse)
Secondary sides voltage is 28v
Not really. You can do what @linsus said but don’t open it up and plug it in…
