Helaas houd mijn kennis op hierna op. De twee spoelen in serie zetten is me nu duidelijk. Wist alleen niet dat de manier waarop, nog van invloed kon zijn op de werking. Ik zal het zo gaan aansluiten zoals door jou getekend, alleen op de inkomende voedingsdraden aangesloten op de trafo (rode en zwarte draad) daar&nbsp;meet ik&nbsp;geen 220V! Dus moet ik het op de voedingsprint gaan zoeken. Enig idee welke waarde thermische zekering (temperatuur) ik moet gaan gebruiken? Dank in ieder geval dat je de moeite hebt genomen het een en ander te verduidelijken via de foto!

So I made a short circuit in one of the circuitbreakers of my&nbsp;house and blew up the thermal fuse of the AV7000. I have rewired the red AC wire by bypassing the thermal fuse&nbsp;but I still don&#39;t have any power on the transformer. Sh1t, I thought it was only the thermal fuse that got defect. Hope someone can give me some advise what could be wrong.
