Autoradio Always pulls the battery lesson after 2 days stand time knows who advice? So the battery is new Auto Radio is a With bluetoth 4x100w Now my problem if the car is standing times 2 or three days the battery so teach the nix more goes I tried to measure what the radio is so current So if it is connected to continuous current Then the yellow cable from the radio 10.5 I think mA but exactly I didn’t have amperemeter on 20.m stand as it was in the instructions. Since red cables 13.9 mA at 20.m The radio was off at the test If I connect it so that it only has power when the ignition is on Dan has the yellow cable 10.5 mA at 20.m And the red cable has 0 or nix I don’t know which values are normal or should be but I do seem to pay very high for a switched off radio
