help please - lost power to cigar lighter , dome light , map light and more 1972 dart

1972 dart 318 daily driver

i was using a small air pump to fill a tire with air ( not the best idea i know , but have been using it a lot lately , no problems before ) plugged into the cigar lighter outlet . anyway it was going along fine for a few minutes when it suddenly stopped . i put the lighter itself back in , it did not heat up . i checked power to the wire attached to back of lighter receptacle and it did not have any . checked all fuses with test light , they all lit up ok . the instr. lps , only with the headlights on . also changed that fuse , same result . map light , dome light , glove box light all are not coming on . hazard flashers also not working . can it be the relay delay ? would that cause all the other stuff to crap out ? looking around nothing appeared melted or any burning smell . lights work with headlight switch , turn signals work . instrument cluster lights appear to be working . dome light does not , even with headlight switch wheel turned all the way left . not sure what to try or check next . any ideas ? thanks
