I have a switch with a charging issue. The charging port was broken, so I replaced that. The switch charged, but not proper.
Did messure for shorts and found two shorted caps near the MAX 77812 IC
So I removed the 77812 IC, but short was still there. Removed the caps, still short. Even tried removing the BQ and M92t, but still shorted.
Mariko rev, and in this case diode mode is useless… from memory typical resistance to ground on this rail is approx 14 ohm - not a fault… as i mentioned this chip does not relate to charge functionality and your chasing a red herring down a rabbit hole for no good reason
