Hi I have a 820-00165 with a known good and working DC-In board, currently that is the only thing connected to the board. No green light on charger.
PPDCIN_G3H = 15.04V
PPDCIN_G3H_ISOL = 15V
PPBUS_G3H = Moves around between 0.6V and 1.4V in no specific pattern (Measured on both sides of F7140)
PPBUS_G3H resistance to GND measures OL
PPBUS_G3H seems too low. Any ideas?
Boardview and schematic attached.
