MagSafe 2 charger 45W wire replacement issues

Text:

Hello,
 
I have replaced wire of charger magsafe 2 45w. Now measure pins, and pin2 and pin4 gives me 0,8V power. Maybe something is wrong with charger ?
 
Maybe it gives that power because wire from china ?
 
Thanks for any answer

I measure magsafe 1 charger from macbook pro 2012 mid, ant pin2 and pin4 shows me 6,7V and something like that. But magsafe 2 only 0,8V±...
 
How to be sure charger works well ? I don't want damage macbook air.....

Then i measure charger wire.... charger end metal trim shows me 3V with all pins inside. It is normal ? Its only on magsafe 2. I try measure magsafe 1 on metal trim and pins, shows zero :)
 
By the way, macbook air 2014 have any safety on charging port or etc ?
 
By the way, on magsafe i measure pin 2 and tryed short pin 4 with pin 5, then i got 15V output on pin2 and pin4. So looks like charger works...
