2 MagSafe 2 charger 45W wire replacement issues
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

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...

on my magsafe 1 I am getting around 0.2-1.0 V and on my magsafe 2 I am getting 3.16V. I am not well versed in how the plug its self works, but normally if a magsafe connector is a knockoff - it will always have the 16-18V on it and never go into standby.
Try shorting pin 2 or 4 to ground, then lifting it off of ground but still measuring pin 2 or 4. Mine jump to a few volts like it tries to activate to charge but then goes back down to .4-1.0v
