You didn't have a problem, I did. It was my Yamaha road Star. When I pulled out the headlight bucket to put in the LED a wire must have been pulled in the driving lights and shorted out. As soon as I turned on the LED the fuse blew.
A pack of fuses later I bought a breaker and tested all the wiring. As soon as I would put the H-4 bulb back in and replace the bucket it was fine. Just call it one of those WTF moments. After messing with it for a day or so Curtis sent me 3 different LED bulbs. I installed each one and the breaker would go off.
I put back in the H-4 bulb and hit the lights and was ready to say the LED's won't work in a Jap bike. A few seconds later the breaker went off... I pulled all the wires going to the headlight and driving lights and found one of the driving light wires stripped. I guess it just happened when I first pulled the bucket and the extra length of the LED made it touch the ground. The shorter H-4 bulb pulled it away from the ground.
Lesson learned that not everything that seems logical is. Thanks Curtis for helping me by sending 3 more bulbs so we could figure out if it was the LED. Curtis was concerned enough to do this to insure his product works correctly. I now have one of his new ones in it and it's fine. :up:
Ya, I also own a Yamaha. A great bike that I made look like a 50's Harley. 102 CI, air cooled, V-twin handles and rides great. Always starts and I never worry about it breaking down. In fact my HD Fatboy is up for sale because this bike kicks it's ass...
