Tail light out

Tail light is out on my 03 GSXR. It's integrated and I've checked all the wiring to make sure there are no loose connections and reseated the ones that I could. Pulled the Flasher relay and reseated, but nothing has worked. The turn signals up front are flashing twice as fast as normal. I know on a car that this means there is usually a bad bulb on the circuit. All the fuses are good too. I haven't hooked up a volt meter as I don't have one, but I'm thinking it's either a bad relay or tail light assembly. Any suggestions?

Does any of the taillight work or is it just the turnsignal portion that's not working?
Is it an LED integrated light or does it have an external integrator?

I believe it is an LED integrated light that doesn't use the stock wiring connections, however it is wired into the stock wires. The light was installed before I bought it. Two wires direct to the back side of the LED and two wires going into each of what looks like where you would plug the regular bulbs into. No lights come on at all - running light, brake light, or turn signals. When I jostle the wires, still nothing.

Looks like this - http://www.gdlcycles.com/asp1/modeta...emID=2010-0238

Are the fuses good?
Did you check voltage at the wires at the light?

Fuses are good and I don't have any tools to check the voltage. Will be stopping by O'Reilly on the way home to pick one up. Does the front turn signals flashing at twice the speed generally indicate a particular issue?

Bring it by Big D's house and he'll fix it up (or try to, anyhow)...or at least use a volt meter (or you can borrow mine) to check if you are getting a signal. Lot's of times, fuses "look"/appear to be good and they are not.

If you can't figure it out, give me a call and I'll walk you through a few things to check.

Sounds like you're taken care of here...

Its one thing that will effect all of them... so either a ground, LED circuit or an integrator. If a fuse was blown at least the turn sig or brake light would work circuit-depending.


,,,,, nevermind; can't believe I dont have a wiring diagram for your bike.... wow...

tested all the voltage - 12 at the battery, 11.20 on the main power connection to the tail light, other two read ~.04...double checked all fuses again - all good...looking for a new tail light now...appreciate all the help - will post if that fixed the issue

Check ground too since you're there. Unplug the connector go from the connector ground to the battery using continuity. Make sure the ground is isolated.

If your going to go to the trouble of taking it out, just hook it up to a known 12V power supply to check it for sure. (if you have a power supply)

IMHO, this is a must:

I use it weekly to even move seats when they are on the bench. Mine has a build in voltmeter to, so you can provide power or ground as needed.
