I'm not qualified to do brain surgery and I probably shouldn't do mechanical stuff either. My bike is not a good patient.
I have a feeling a lot of Road Glide owners are like me: They have a passion for their shark nosed machines but not unlike an unscrupulous stockbroker selling crappy stock, they'd like to put a little lipstick on their pig.
I liked the newer Kuryakyn driving lights/turn signals for the Road Glide, so I ordered a set off of EBay for a hundred bucks less than retail. When they arrived, I turned our middle garage into my own Harley shop. For like a week.
It all went well for a while. I got the fairing off, headlights taken off and after screwing up the turn signal plug-in and then the two additional plug-ins, then several connectors, I finally got the wiring wired up. Then I connected the driving lights. Like Clark Griswold after hooking up the Christmas lights, I had my wife do a drum roll. The lights worked on one side but not on the other. I would walk away, come back and then they worked on the other side but not the original. Some times the turn signals would work, but the driving lights wouldn't. Then the driving lights quit all together.
Frantic, I spent a week taking apart lights, blowing up fuses, buying electric testers (two--I blew one up), running to auto stores looking for bulbs, trying to find a bad ground wire.
Finally, a guy at work who knows something asked me if I had the Kuryakyn units bolted to the frame when I turned the switch on.
"What does that matter," I asked.
"Dumb-ass," he laughed, "the frame is your ground."
I took the rest of the afternoon off, ran home and had the Kuryakyns on in time for Sturgis.
