I purchased and installed some LED signals for the back of my FXR. I have running lights, but when I turn on the signal light I get no flash. If I take my test light and touch it to the live wire anywhere in the circuit, my flasher relay will kick in and my turn signal will work, left or right, whichever one I'm playing with. This made me think that I had a ground problem somewhere. I checked and cleaned all grounds on the bike, nothing. A friend says that maybe it's not the addition of the ground that makes it work, but the addition of resistance of the test light. I'm certain that if I wire a small light to each side of my turn signals, they will work. My question, is there a way for me to add this resistance to my LED's so that my flasher relay will kick in, without adding lights to the circuit. I hope my question makes sense.
