Dear forum users, there is a problem and I am looking for a reason and solution. Describe the connection and the problem itself.
We are renovating the flat, power supply to halogen lights taken from the existing cable from the ceiling (3-pole - neutral and 2-phase with the double switch 2 keys). Connected with a cube from one key to 7halogen and from the other to 1halogen, common to both. It shines everything as it should, however when it extinguishes this one halogen it flashes approximately every 4-5s; Could it be some short circuit on the cable old who's in the wall or what could it be the fault?
