Am avut si eu mai demult acu vreo 3 ani un defect indentic ca al tau , asa mia spus si mie clientul ca se aprindea foarte greu si dupa nu a mai vrut sa se aprinda deloc , dar nu mai stiu exact ce defect a avut  :scarpin  tin minte ca am schimbat ceva conzi din secundar sursa si primar  , mai ales pe tensiunea mica de 13v , deci integratul la mine a fost ok
