Since I was not getting the right voltages I checked the diode under the microscope and found that one pad was not soldered correctly.At the moment the MacBook range is comprised of the MacBook, MacBook Pro, and MacBook Air. This voltage drop is needed in order for Q7010 to open and send the same voltage on pin 1 (6.8V). The voltage on pad 2 of C7012 needs to be around 6.8V because of the Zener diode (GDZT2R6.8) that pulls down the voltage. The problem was with the bad solder on Zener diode D7012, and I found this by measuring the voltage on the capacitor C7012 - on pad 1 of the capacitor I was getting around 15V (voltage from the MagSafe) but on the pad 2 of the capacitor I was getting around 14V which is not good.
