Sounds like a fuse.
An issue which may be related with bikes of that age are 3 places where the wiring gets chafed.
Both screws which hold the rider's seat on are a shade too long and the wiring harness runs immediately behind and can get damaged.
Also under the pillion seat on the left side of the bike towards the rear the wiring runs round the edge of a bracket on the frame, and this too can chafe through.
