I have replaced a 5k potentiometer on a 24v battery charger, I dont have a clue how to set it via the multimeter, the potentiometer is positioned close to the DC output, please help
What's actually happening is I dont know the value to set the potentiometer to and everytime I switch the charger on the ac fuse and mosfets blow, if you can let me know what info you need, I can try and get that info for you
The charger was working, our power cuts stopped, so i packed the inverter away, after a couple of years I pulled it out as we need to use it, the fuse popped along with 2 mosfets IRF740B, so I just changed all the caps, diodes, potentiometer...etc but little did I realize the potentiometer needs to be fine tuned to my circuit

It was pretty silly randomly changing components, particularly the potentiometer which needs setting - do you still have the old one?, if so put it back in.
