Re: Macbook Pro 13'' 2017 A1708 Won't power on with battery connected.
I don't have access to the schematics right now, waiting on junior to get his haircut. Check the common signals between the battery and the display.
Suspecting the smbus lines.
Remove all power. Meter in diode mode.
Remove the display.
Red meter probe to ground.
Black meter probe to smbus SCL line. Measurement?
Repeat for the SDA line.
Now connect the display. Repeat the above measurements. All with no power and meter in diode mode.
