Macsafe won?t show green light when MagSafe is reversed

[Chuck60]

I have 2 - 820-2915b boards that I repaired that will power on with magesafe in one direction but if I reverse the connector to the other side it won?t power on. Not even a green light. I tried several dc in boards but have the same issue. I?m lost with these 2 they are both 820-2915b

Post PPDCIN_G3H, PPBUS_G3H and 3V42_G3H voltages.
Did you try another charger?
Use original 85W one...

I?m sorry for the late response but it was a loose resistor on data line
