mam problem z płytą DAZAAMB16E0 z acera ładowanie działa tylko wtedy gdy wepniemy baterię po podłączeniu zasilacza. Gdy podłączymy baterię a póżniej zasilacz, włącza się zabezpieczenie zwarciowe. Na samej baterii działa, na samym zasilaczu też. Po podłączeniu baterii na lini VIN mam od razu 16v, mosfety wszystkie sprawdziłem i wyglądają na sprawne.

Hello!

Check the transistor PQ1.
If it's fine, measure the voltages to ground on pins 1, 3 of diode PD8 and on pins 1, 4, 8 of transistors PQ1, PQ22 with the power supply connected only (without battery).
