Hello everyone, I need some help with a battery charger I may have ruined by accident. First off it an ultra power up240ac plus. It’s capable of working off a 110 or 220v plug with the flip of a switch, or dc power up to 18v. I occasionally use it on both ac voltages depending where I’m charging. I goofed up one day and plugged it into my 220 plug before flipping the switch to 220v, I thought I already had it set to 220, I was wrong. There was no pop,smoke,or obvious damage that I could see to the board. Now the charger doesn’t turn on with either voltage with the switch in the appropriate position. However the charger does still work on the dc input so I know the damage can’t be too detrimental. I’ll attach photos of the board. I’m relatively handy I can solder and identify some electrical components. No obvious fuses or anything that I can see. Anyone have an idea what crapped out? Or a way to troubleshoot what did? Thanks everyone.
