I removed the following from the continious 12v line feeding to my (old car radio : Sony XRC 4120) I've just replaced the car radio, but I was wondering if there is anybody who knows what this is.
I get 12.5v through it when connected straight to the battery, and it does not show a reading when tested for resistance. Could it be a heat sensor of somekind ???
