Another mac not charging battery
I've been reading these answers but haven't found a solution for my problem yet..
I have a early 2006 macbook 13 wich will not charge the battery.
I am certain the battery and the AC charger are fine. (I've tested others).
- Runs fine on battery
- Does not run on charger only 
-When plugged in the MB recognises the charger and the light is green (the symbol turns into a plug but states 'calculating' and doesnt change)
- Resetting SMC and PRAM did not help.
So my guess was it must be the Magsafe DC board and i took the MB apart. But while inspecting the battery connector cable thats connected to the logic board i saw that one of de holes for the pins is blackish: http://tinypic.com/r/bi8k2c/7
Seeing this I'm not certain i'ts the Magsafe DC board that's faulty.
- It can be the Magsafe DC
- The battery connector
- Logic board
Is there any way I could do some tests to know for sure wich of the 3 is faulty?
