PPBUS_G3H =
Red probe on ground 0.45v
Black probe on ground 2.3v
Changed the C7125 (didn't work), checked the rails and OK...
We got delivered new U7100s, so I changed it and get 12.52v ppbus, but something strange is happening.
Fan spin but yellow light on without battery plugged in, battery...
Hello it's me again...
Got a board with liquid damage, it turns on with battery plugged and Yellow light.
Water damage was around U7100, replaced damaged components and the U7100.
U7100:
DCIN 20v
Pin 17/18 3ohm
Pin 19/20 5ohm
Pin 27/28 21ohm
PPBUS_G3H diode mode ok, but 0.8v
I'm gonna get me the schematic, board viewer it's not enough, will scavenge resistors from the donor, then I will report.
This is my reading, reverse is the same, it reads something for a second then I get this...
"What is the diode mode to ground reading on PPBUS_G3H?"
I get 0L reading on my multimeter, sorry I miss read...
I have tested the rails and I don't see disconnects or high ohm.
I see 778ohm across R7121 and 3.9khom across R7122.
I'm sorry but I'm a noob so please be patient with me
Hello
I have orange light on the charger, get 20v at the u7100 DCIN, i have 1 volt on ppbus_g3h even without the u7100 on the board, don't see any short on the coils
I replaced the u7100 since it was blown.
