matic написав:Remove the chip PU5 (MAX1702) from the board and repeat the test suggested in post #16. What is the voltage to ground on pin 2 of resistor PR159 in this case?
Do not connect the charger or battery to the board with the chip PU5 removed.
Pin 2 on PR 159 have between 1,81-1,99 V. Is not stabile.
