I had a mishap of plugging in my IPOD FM transimmitor and the cap of that screwed off somehow in my bag. I accidently plugged it into the lighter. Then I tired plugging my radar dertector back in and none of my things worked, not even the lighter. I replaced the lighter. The Fuse was fine, is there anything else to look for or replace ?

 

pull the cover off, and look at the wires.
