i Have a 1984 hichhiker nuwa just bought it. I knew the people who owned it the are very picky people its in amazing shape for its age. Everything has been working fine till last night i was hearing a clicking noise but nothing ever changed no light flickers not anything till this morning i turned on the 12v radio in it to listen to breakfast with beatles and everytime the clicking noise happened the radio shut off then came back on a minute later then the click a few minutes later and off again. not sure what to look for found it under the step which was warm not sure if its got a fan need to get some tools rounded up to tear it out of its spot. not reall sure what to do from here.
