Hi !
In this schematic of a radio , can you explain me what these wires do ?
So , I highlited on the schematic the switch from the volume potentiometer (the volume control also turns off/on the radio , it is a potentiometer with a switch) , there isn't actually 1 switch , but there are 2 switches (highlited in the GREEN rectangle on the schematic) , when the volume is off , there is no continuity between each one of the pins but if it is on , there is continuity like shown in this diagram : (the diagram represent the pin of the 2 individual switches that are both triggered then i rotate the potentiometer's button to the left , it controls the volume and has an off state also)
So , what is the red wire ? what is its job ?
If I hook the radio to batteries and the yellow wire (point 40) to pin 2 and 4 , and the + of the batteries to pin 3 and the red wire to pin 1 and i turn it on , nothing happens , the radio starts(works flawlessly) only if i disconnect the red wire , so there shouldnt be a connection between the red wire and the + of the batteries ?
red wire = the wire that is highlited with a red rectangle in the schematic
green rectangle = the 2 switches (see schematic)
