This board sometimes no power. If I reconect the battery it works again 1,2 days and then no power again. I need to reconect battery each time. Any idea?
Battery charge, discharge correctly. Can see the %
PPBUS with battery 8.42V
I found corrosion arround Q5530. I replaced this and checked it goes to C5411 but still the same.
I measure on C5411 and I have 3V and 0.5V in both pins. This is on the faulty board that run slowly.
On another full working board I have 0.5V in both pins. Any hack I can do? Any idea how to solve...
