I just bought a new to me left hand switch set. I installed it the other day and tested the turn signals, they worked then. I tried them again today, and the left side worls but the right side doesnt. It doesnt light up, it doesnt blink, the relay doesnt even click. I have no idea where to start looking. Any ideas? Im not to sure if if matters or not but my bike is an 86 and the switch came off of a 90. the plugs were the same, needed no modification to make it fit.
