Ok guys, I know exactly nothing about wiring. Its so easy but so complicated for some reason. I bought the bar end turn signals from M750Dark, here they are:


Before I mounted them I wanted to make sure they worked, and they didn't. So heres what I know. I plug in the yellow wire to the striped signal wire behind the headlight. As seen in the picture the signals don't have another wire running with the yellow wire, so it has no ground wire. It does however have these spring like wires sticking off of the bolt that runs inside the bar. I'm guessing this is what the ground is. The bar end signals did not work at all, but the rear ones did. I initially thought it had no real good ground so I bolted a real ground to the bolt and it still did not work. This is all I know

Heres what happened. The first time we hooked it all up to test them, the rear turn signal blinked real fast just like it does when it does not have front turn signals at all. Then a fuse blew.
Got another fuse, this time the rears were not blinking fast, I think it has something to do with the relay, but were blinking normally, still no sign of life from the bar end signal at all. Then the fuse blew again.
Got another fuse, now no signals are working at all. We test the relay and its blown. And we stopped working. Once I get a new relay I'll start in again. You can get them at auto stores right? Also I have aluminum clip ons, will that make a difference once we get all this figured out as far as grounding?

so theres the story, long I know, but I thought I'd be thorough that way we can be progressive. I definetely need help on this one, but I am confident you guys can help me though it. Thanks

I'll take a stab at this one.

It sounds as if there is a short. This is the reason the fuse and the relay popped.

When the turn signal relays "see" more resistance in the circuit they blink faster, think about adding a trailer to your tow rig the blinkers generally blink faster, or if you have a different impedence LED or something.

Thank you Yellow Duck!!!!!

Finally someone replied!! haha!

I know the signals blink fast when one end of the bike doesn't have its signals hooked up, so that was expected, but its weird to me that when i do hook up the signals that nothing changed. One thing I was thinking is that maybe I should have hooked the ground into the other wire, as I was just grounding it on the bike. Maybe I'll have to run a real ground wire to the turn signal connectors? Could this be the reason for everything poppin? Hmmm

Any other advice would be soo helpful!

P.S. Us yellow duc guys stick together huh, but mine used to be black! dangit!

Ducati wires the ground through the flasher so you can't use the spring wire ground. There are two wires wired to the stock blinkers you need to wire directly to BOTH of those. One runs from the switch to the bulb and then back to the flasher then to ground.

I have, in fact, used the spring wire ground on those signals without any problems.

But, if that's the problem, you might be able to check it by just running a jumper from ground to a triple clamp or something to give both signals a ground source. (It'd depend on your bars/clip-ons and whether they make a good short to the fork tubes.)

I took Laura's off her bike for a track day a while bike, but I'll be putting them back on tonight or tomorrow, so I'll let you know if I get any ideas while I'm doing it.

I wonder why it is not working for me then. Deadpan do you think the wiring is different between the years of our bikes? I think I am going to have to tinker a bit more. Definetely post your results deadpan. I will greatly appreciate it.

Patrick-
Get a continuity( or ohmmeter) tester. Connect it to your negative battery terminal then to the bar, must sure it can function as a ground. Then get to the bulb in the turn signal, remove the bulb, connect the continuity tester to the spring and then to each bulb connection in the turn signal to find if the spring will function as a ground. If not maybe it is the nut on the end or something else that has to be grounded. That is all you're really dealing with one positive and a ground somewhere, you just have to find it. Hope this helps, and yes the yellow ducs are sweet.
