Becarefull in your measuring as you can easily damage either your MagSafe charger or your logic board! If I understand correctly the MagSafe connector is not passing the power from the power adapter to the logic board. This is not that uncommon as the pressure & heat of the connection distorts the plastic so the connection within the MagSafe connector. Here is the IFIXIT guide to replace it: MacBook Core 2 Duo Magsafe Board Replacement and here is the needed part: MacBook MagSafe DC-In Board Also here is a good reference on what to check with the MagSafe adapter as well as the connector its self: Apple Portables: Troubleshooting MagSafe adapters and here’s a good diagram of the pin assingments: Wikipedia - MagSafe
