Hello,
I am having a bit of an odd issue with a Switch that I have. The unit won't power on but when it is plugged in, it is drawing 14.7 volts at 0.5 amps and the battery, which was stone dead when i got it, was reading a voltage increase with a multi-meter and seems to be taking a charge. I unplugged all of the components from the board, did a bit of a visual inspection and there is no signs of corrosion or liquid damage. When I plugged the unit in without the battery, it would draw 14.7 volts at 0.09 amps and just stay there. I tried testing some of the capacitors around BQ24139 and M92T36 and didn't notice any of them shorted.
Any idea what I can do to help pin down the issue?
