2009 Triumph Rocket III Classic
So this seems to be a common problem with these bikes. I've had my 2009 Classic for one week and the lights have never worked. I assumed it would be something simple so I didn't worry about it, but after ruling out the fuse, starter relay and bulbs I'm left with only the switch and the wiring harnesses under the tank. I will check those tomorrow. and put a volt meter on the bulb plug as well as check for continuity between the switch/bulb and the switch/fuse. Any words of advice? The running lights work but nothing to the bulbs. The highbeam indicator does not work either. I changed out the starter relay and fuse with new ones, nothing. Is there some common issue that pops up repeatedly that I don't know about?

Thanks, guys.
 
Are u using a 5 prong relay
If your wiring is orginal a 4 prong relay will eliminate headlights. That would b a good place to check from there it goes to the hi low switch also a good place to check for power.
 
Turbo, you must be some kinda genius. That's twice you've pulled my bacon from the fire. Advance auto parts had the 5 prong relay for $20 and it worked like a dream. Brother, if you ever find yourself in Kansas, USA all the rounds are on me.

Ah, too bad, you spelled compliment wrong, now I have to take that back

I'm actually a terrible speller myself, before spellcheck I always had to ask my wife, she can spell words she doesn't even know the meaning of.
 
My computer has spell check
My phone does not
Some times i use google
Some times i do not
I had a stroke a long time ago (drinking to much coffee) and after that i could spell 3 and 4 letter words perfectly backwards also would reverse phone numbers. Some of them would talk to me and some of them would just hang up on me. Lol
