Macbook 820-2610-A

[lcdcaps1]

Hi
I have an 820-2610-A
Board was working

U7000 is removed and was in the process of rebuilding some pads around u7000 but then realised that there is a short on CHGR_PHASE.

I confirmed this on L7030, pin 1 and I also have a short on PPVBAT_G3H_CHGR_REG_L confirmed on pin 2 on L7030 and on L7301 pin 1 there is a short (that would be because it is connected to pin 2 on L7030) but on pin 2, PPVBAT_G3H_CHGR_REG on L7301 it is shorted as well.

If I remove the L7030 Coil the short is not there on CHGR_PHASE and the coil has continuity when tested out of the circuit. When I put the coil back the short comes back.

I have removed F7040 and F7041 to see which side the short is but wanted
The short is on pin 2,
short to ground on pin 2 is 0.3 ohms

removed fuses F7040 AND F7041,
pin 1 PPBUS_G3H and pin 2 PPVBAT_G3H_CHGR_REG

short to ground on pin 2 is 0.3 ohms
pin 1 of F7040 AND F7041 Is in the mega ohms


I injected voltage on L7031 pin 2, started with 1v and 0.35amp
and its drawing 0.34 amp


I increased to
1.50v and drawing 0.51 amp

Nothing is getting hot
My wires are only thing getting hot

Please can any experts for these boards 820-2610 get in touch
Thanks so much
