@sis6598116 let's give this a try. Set your meter to the 20V DC scale

Plug your Magsafe in and make sure everything is properly connected. Now, deep breath ;-) You ready?........ Connect the Black probe from your meter to anyone of the ground connections (marked in Red) and touch the bottom connector (1st yellow arrow) with the Red probe from your meter. You should get ~18.5V (little less is ok too :-) Then do the same with the second contact (from the bottom up, 2nd yellow arrow) and take the measurement. Let us know what you discovered.
