1 Looking for a short on VCC MAIN, injected 4.2v blew component
Title pretty much sums it up. I soldered a wire to a cap near the pmic. I hooked the positive up and heard pop and saw a little puff of smoke.
I had a diode reading on vcc main of 0.152, thats why i tried to inject voltage, but as soon as i did the voltage limiting on my dcps kicked in and voltage went to 0 while amps went to 5.16.
The strange thing is that i went through each component and cap on main but didnt find the fried component. Any ideas on what happened, this is the first time ive injected voltage into a line so im unclear on safe voltages to find a short but not blow it off the board.
Es esta una buena pregunta?

pts8091 post a good picture of where you soldered to the Cap. with your question. That way we could try and trace the circuit and see if we can find the smoked component. Agregar imágenes a una pregunta existente
