I just bought a 1982 GL500, everything worked perfectly... I removed the toolbox and the left rear turn signal came loose. I rewired the turn signal and now none of the turn signals work and the headlight does not turn on. The brake/tail light still work. I replaced all fuses, checked for loose grounds and cleaned all the connections and switches. Still nothing. Perhaps I'm not finding a loose ground? Please someone help! Any suggestions will be most appreciated!
