Automatyczna ładowarka akumulatorów ołowiowych AVT 3120 - warto zrobić?

Witam siedzę i rozlutowywuje to ustrojstwo jedno jest pewne po wlutowaniu dławika zpowrotem zaczynają się dziać te dziwne rzeczy jak dławika nie ma zasilaczem mogę śmiało do 14 V kręcić i nic się nie grzeje Dodano po 6 : Brak diody D3 nic się nie grzeje Dodano po 21 : T1 włożyłem drugi to samo się dzieje napięcie z trafo po mostku ma niecałe 12v, na zasilaczu regulowanym też się grzeje Dodano po 1 21 : T1 wyjęty nic się nie grzeje dotkne do ścieżki napięcie na zasilaczu spada, sprawdziłem wszystkie kondensatory nic co mogło by zwierać oba T1 mają podobne parametry rezystancję i test miernikiem wychodzi podobnie Dodano po 2 : Diody zapalają się idealnie, napięcie na IC1 5,08 brak 30 V na IC2 Dodano po 13 : Nasunęło mi się jeszcze jedno pytanie czy na diodach D1 i D2 mierzone napięcie pomiędzy GND z jednej jak i z drugiej strony diod powinno być takie samo ? Po podaniu napięcia na AKUP na złączu POW mam identyczne napięcie Dodano po 23 : nie znam się ale z tego co wyczytałem diody mają przepaść jeśli chodzi o czas reakcji
