First of all, check resistance to ground at L6995 (ohm scale).
If get less than 30K, MCP is probably dead.

For green light, test another Magsafe board.
Post U6900/01 voltages and check continuity from U6900 to Magsafe central pin.
 
U6900 pin one is 3.4v
tested second MagSafe still the same this is good MagSafe
l6995 ohm I get reading of 5.322 k on my multimeter
u6900 pin 5 there is continuity to MagSafe central pin

You didn't post voltage for pins 4 & 5 of U6900.
You may get Magsafe light at the end, but such low value on 3V42 rail makes me believe you are wasting the time...
