jgraffis ... Trace was blown... Ran a wire but still no green light... But we have 3.41 V now

 

[TCRScircuit]

Onewire and adapter sense are both at 3.40v now but no green light

 

[TCRScircuit]

I've had a board with the same adapter sense and onewire readings before.... u6900 is bad... And of course it's stolen off all my donors... More on the way thogh

 

[jgraffis]

If SLC_bcacok and 3.42 is present then you have an smc issue

 

[jgraffis]

Also make sure the old trace is not shorted to ground. This is unlikely but had it happen to me. The smc should be sending signal for green light. I would replace smc next.

I've had onewire and Adapter sense be the same 3.4 v and U6900 was bad... When I was troubleshooting this board I replaced u6900 from one I had on my mat... now that I think about it, that u6900 that I used may have been a bad one

 

[TCRScircuit]

No shrt on trace

 

[jgraffis]

Put old u6900 back on

 

[TCRScircuit]

jgraffis No idea where it went lol... More are on the way

 

[TCRScircuit]

Mark as solved now fixed

 

[jgraffis]

well what was the fix?

 

[TCRScircuit]

@igraffis... The wire from u6900 to u6901... Then I got trolled by a bad DC in board... Plus the ISL and q7030 and 35.
