Hello, this is my first post. I have a 80' kz650E and have done a 75% ground up on it. I haven't messed with much electrical on it as there was little need to, however as I plugged my headlight back in (after about 3 months) it didn't work. The running tail light works and I have checked the grounds to make sure they are good. I have taken off the front turn signals, but left the rear and they work fine. Any help is appreciated. Thanks!
