Hey, recently I noticed a problem that won't let me sleep, my cigar socket won't work. These are my observations:
-the fuse is intact
-black wire is connected to grounding as it should be
-red-white wire has +12V on it when key is on ignition
-yellow-black backlight wire doesn't have any voltage on it
-backlight bulb was blown
-it seems that it should work, but when I connected a cellphone charger the charging went on and off in short periods altough the multimeter showed const 5,5V on the charger pins
-other 12V supplied stuff didn't work at all
-I connected all that stuff to radio power wire and it worked fine then
For sure the problem isn't connected with the socket or the devices themselves cause they were working fine on other +12V wires in the car.
