sorry all fuse are good. When I connect the power adapter only to JE701 (UF500), I do get PPBUS_AON = 12.02 V, but not on the other two connectors JE700 and JE900. On the tester I have 5 V 0 A and PPBUS_AON at 0 V.

all fuse are good. i complete my work. I have PPBUS_AON= 12,02V , when I connect the power adapter only on the JE701 (UF500), I have on the usbc Tester 5V 0,250A the other 5V 0A

P_IN : 0 AUX_DET: 0V SMC_RST_IN: 0V VDDA: 0V VDDP: 0V EN_MVR: 0V AUX_OK = 0V A/BMON = 0V , 0V I thinks the problem is before, I use 96W power adapter apple

Hi, i have this board, very clean no liquid, the original battery seems dead (0V) (if connected stay at 5V). I put a new battery on the Mac but no charge (20V 0A). I haven't the light on the magsafe 2. i test the usb-c with tester by Qianli, all ports seems good and no LDO in short. I haven't...

PP1V25_S2 = 0,266ohm R770F =0 ohm ok after replacing L77D0 PP1V25_S2=1,25V but no work same problem

yes I have some voltage on buck

buck seems normal (flexbv database diode mode). do you want all value?

thanks for your answer U8100 LDOs PP1V2_S2=1.1V , diode=0.328 PP3V3_S2_UPC=3.3V diode=0.458 PP1V8_AON_MPMU=1.8V diode= 0.366 MPMU_VREF_ADC=1.47V diode 0.158 U7700 LDOs PP0V72_S2_VDD_LOW=0.740V. diode=0.270 PP1V2_AWAKE_PLL 1.199V diode=0.380 CAP_PPSPMU_VLDO9=1.803V. diode=0.5...

Hi, I have an A2337 (820-02016) with 5V and 0.02A and 0.04 A (cycling reboot my tester USBc) on both USB-C ports. - PPBUS_AON = 11.99V - PP3v8_AON_VDDMAIN = 3.8V - PP5v_S2 = Missing - PP3v3_S2_UPC = Missing - PP1v25_S2 = Missing - PP1V8_S2 = Missing - PP3v3_UPC0_LDO = 3.292V -...

hi, ok for the green light. I check the data cable is OK. Voltage: SDA= 0,1V SCL= 0,7V in diode mode with battery, no power: SDA=0,456V SCL=0,456V in diode mode without battery, no power: SDA=0,52V SCL=0,52V

Hi, i have this board with orange light magsafe 3 but not green, when I test the Mac in MRI, can't detect power adapter. I use an original power adapter 96W with original cable. the board is clean, no liquid, nothing burn. I try the board without battery (orange led), is it normal? the Mac work...
