I am repairing a ZIVAN Battery charger NG9. I don’t know what the reason for the breakdown was. When opening the unit, all very new, manufactured in 2020. I have checked fuses and critical components such as rectifier diodes and FET 25N120 transistors, they are all ok. The problem is that I find two burned charred NTC resistors. They are R19 and R26. I don’t know its value and ask for help in case any colleague has the scheme or has had a similar problem and can help me. Thank you for your time dedicated to me.
