There are two white wires disconnected, one marked and one on the right almost below the inverter. Disconnect brown bridge and connect any of the white ones and see if it sounds. You should help yourself with someone on the street who keeps the bell tight.
From what I see the brown is not connected to anything, the bridge should make it to the terminal that is just to the left (That would be the first test) then the rest. Comment
The white wire that marks in the photo connects it below where the bridge in the number had made the other white wire was never connected. That is safe. It still sounds good but the buzz still does not sound. Until 1 week ago it always worked. My mistake was not to take a picture before taking it. I also did not understand what it means by investor.
The inverter is the set of contacts that cut off the communication, it is the other white cable loose and twisted. Did you try connecting the brown to the terminal on your left? That is PM (supposedly negative)
Hello chame90 I would like to know if you have followed the suggestions and if you have solved your problem Thank you and greetings on the day of the homeland.
I'm glad. Was it solved with the indicated bridge or otherwise? just to keep the record and serve another user. regards
