My horn, interior light, flasher and radio have stopped working in my Triumph GT6 MKIII. Checked the bottom fuse (Of the 3 in the original fuse box). It was blown. I changed it and it promptly went again. I took my dash out and checked for dodgy wires and changed a connector on the flasher unit. I put another fuse in and it didn't blow but none of the above instruments would still not work. Help.........Any suggestions welcome
