the speed pulse is at the back of the clocks. the best way to test for this is to get a NON flashing led put a wire on to one leg and put that to earth and then put a bit of wire on the other leg and with this one you need to test the wires at the back of the clocks. a speed pulse does what it says on the pin, it pulse's when you move. i get a sharp metal spike and put the test wire to it and probe the wire, you dont have to go fast so just creaping fowared will work. a speed pulse goes from + to open circuit to -. when you have the right wire the led will flash when you are moving and stop when you stop. smileys/smiley14.gif
