Lectron pro 10A charger was charging a 3s. I stopped the charge, plugged it into my 12v outlet in my truck to finish the battery while I was driving. Done this several times before. Still works on 12v DC but now nothing from AC. Confirmed cord is good. Oped charger, nothing noticeable. This thing was just working. Any knowledge or experience like this?

Is there a fuse blown in it?

Nope. Don't even see one. Charging fine from 12v power supply

Well, power supplies of all types go bad. Check closely for any dark components. Sometimes really hard to see. Take pics under lots of light, from various angles and zoom into them. Those often find stuff you cannot see.
I had a capacitor go out on my 3d printer power supply, and it wasn't until i bumped it and the ceramic broke apart on it that I found the problem. I replaced the power supply only to have the same capacitor go out again. Turned out to be a mosfet inside the control box had a wire that worked loose and cooked the mosfet, causing the power supply components to overheat.

The same thing happened to my Lectron charger. Check where the power cord plugs into it, mine came unsoldered where it connects to the circuit board. I just resoldered it and it's working now.
