hey guys. Been a while since posting. Must of learnt something!
Am now stuck on a old 820-2580 board. Seconds away from giving up and this post is my last resort.
PPBUS_G3H is not holding and is always changing values. From around 8v to 12.6v.
F7040 is fine and I even changed U7000 off a working board. Same result.
R7020 and R7050 are those sense resistors. I don't quite understand how they work although the readings seem fine. Can't find any shorts.
Possible for some nudges in the right direction??
Thaks again.
