What is the voltage of SMC_RESET_L ? Do you have a green light on the magsafe connector? What is the voltage of PPBUS_G3H ?

[bridges_4u]

Hi mon2

YES. I do have the green light on the charger.

PPBUS_G3H : 12.40 V.

I shall post SMC_RESET_L voltages shortly as there has been a power outage.

[bridges_4u]

Hi mon2, reformatt ,

Please review my findings and advise.

PPBUS_G3H : 12.40 V.

As per post #60. Should be ~12v6.

Flux and remove F7040 off the logic board. Do not lose it. Power up without F7040 so there is no consumer side loading on this power rail.

What is the voltage to ground on the ISL (producer) side of this PPBUS_G3H power rail?
