Triumph Repair: 1979 spitfire, turn signal switch, low beams

Question
Just bought partially restored 79 spitfire. High beams work low beams do not, flasher work turn signals do not.
Please advise as to where I should start to look for the culprit. Perhaps the turn signal switch?
Thank-you
Jordan

Answer
I answered this the other day.
If low beam does not work you need a wiring diagram and a test light and start checking for power at the light and work your way back to the source (the light switch)
If you don't have a diagram let me know and I will put one up on my web site so you can copy it.
