Resistance between pins 17/18 and 27/28 of the ISL6259? Tried known good DC in board?

17/18 3.5ohm
27/28 21.1ohm

"Battery has been replaced, no change."
Tested with known good battery, or just tried new chinese one?

Check system report in about this mac menu.
You should get more information about battery there.

 

[EJS]

New Chinese copy, but 3 different ones were tied, and behavior is exactly like the OEM that was pulled for this issue. System report battery info all seems to be present. Is there something specific you would like to know from there?

 

[2informaticos]

Cycles, charge capacity...
If all this info appears, then communication between SMC and battery is OK.

Check Q7155 voltages.
Also post voltage for U7100, pins 9, 15, 26.
Run ASD EFI version.

 

[JohnB8812]

What voltage do you currently get on PPBUS with just the charger no battery?

 

[EJS]

2info, system report does list, capacity, cycle count, ect.
Q7155
Pin 1 12.6v
Pin 2 12.61v
Pin 3 12.6v
Pin 4 jumps back and forth from 11.91-12.59v
Pin 5 power cycles between 11.58-5.6v

U7100
Pin 9 .412v
Pin 15 .058v
Pin 26 .022v
The ASD pack I have only goes up to early 2013 Pro, this is a late 2013 board

John B PPBUS is 12.6, board only

 

[2informaticos]

You should get proper ASD for test.
EFI version is good enough.

Try the batteries in other system, or get a known good one, even old, just for test.

 

[EJS]

I thought after after early 2013 they switched to ASD 2 which runs through the Apple servers? Do you know where I can get a copys for later machines?

 

[2informaticos]

ASD works untill 2014.
Your machine requires 3S162 version.

Use Google, it will probably find some torrent...

Those errors popped up because some of the cables were not connected. I put the entire machine back together, ran it again and everything passed. I also tried with a working OEM battery, still not charging.

 

[EJS]

Okay, just ran a 2nd time, and now its telling me temp sensor Th2H left fin stackprox is failing

 

[2informaticos]

That will not block battery charge.
But IPBR and ID0R will do.
Check again if these erros went off really.

 

[EJS]

Sure enough, it failed for IPBR and ID0R on this go around, and the other error disappeared.
