indicators not working headlight and brake lights "flashing" instead?

hi there im currently rebuilding a motorbike and ive just got round to the indicators, ive put a new relay on and checked the bulbs and fittings and they are all sound, however the indicators were only working on the right hand side (front and back) then they stopped working ( i think i may have got a cable mixed up..now none of the indicators work and the only lights that flash are the headlight and rear light (only when i turn the lights on) no matter what side of the switch i select....I really dont know whats going on, can anyone please help me?
