Basically I injected 4.2v at 1a I to vsys and shorted the power pins and this diode lit up. The voltage drop across it is 0.137 in one direction and OL in the other.
This seems very low for a diode, and the fact it’s lighting up suggests this is the culprit.
I can’t seem to edit the post, so just want to clarify a couple things. The diode ‘lit up’ on the thermal camera, and It shows 0.137 drop both in circuit and out of circuit.
