Bill,
If there are only two wires going to your flasher then pull the flasher out and put a jumper on the two wires where the flasher was. This will tell you if the flasher is the problem or not if everything else is ok then when you move the arm on your turn signal switch then the front and back light for the direction you are turning will come on and stay on. They obviously won't flash because you don't have a flasher. Then try the other side and the same thing should happen. If this test works then you need a new 6V flasher. My flasher has 3 tabs but there are only two wires that physically connect to the flasher. If yours has 3 wires at the flasher then don't try this test because I don't remember what the third wire is for on a 3 wire flasher.
Good luck,
Les
