Hey guys,

Bit stuck here. My turn signals refuse to work.

I checked, double checked and triple check I
was connecting the right wires to everything
when I put them on. The front signals DO work
as RUN lights, but when I hit the turn signals..
nothing. This tells me my GND and 12v Constant
are connected properly, but again.. no turn signal.

I am a little stumped. I do have LED Bulbs in the front
turn signals, but the back are standard bulbs. Could this
have something to do with it?

Also, the bikes original gauges are gone and aftermarket
ones installed. Is there a safety switch or something that
may need to be connected? Kinda like how the headlight
wont run unless the engine is going?

I have tried them with the engine going and just in ACC
mode and no dice. I have NOT tried hitting the hazard
lights button though.. I will try that as soon as I get a chance.

If the turn signals flash with the hazard light button, then I
know that its just the turn signal switch is goofed.

Any other ideas? Im pretty flustered over this one. Thanks!

Without the right flasher, I think they should still flash, but flash too fast. I could be wrong. Have also read that if you use only two LEDs, the lights should flash normally.

The number for the LED flasher is EP34 and the auto stores should have them.

Did the flasher work before the mods? You could test the wire at the flasher and see if it gets power when you hit the turn signal switch.

Not sure if there's a separate fuse for the signals, but ... check fuses?

All good suggestions here.

I did check the fuses and they are all good.

I tried the hazard lights button and got nothing.
However, the headlight toggle switch and horn
work, so I dont think its the electronics in the switch.

I would think that the LED bulbs would if anything
cause the lights to blink too fast, and also the back
turn signals have regular bulbs in them and they
are not doing anything at all.

However, I will try putting regular bulbs in and report back.

Wish I could say the bulbs fixed it. That would have been too easy.

Pulled out the LED bulbs and put standard turn signal bulbs in so that
all 4 signals would have matching bulbs and there would be no leds
to throw off the flasher. Still nothing.

Front Running lights come on, but no flashing. Back lights (turn only)
do nothing. Dangit.

What gets me is that the running lights come on in the front. Like I said,
I double and triple checked all my wires were matched up properly..
Since the running lights work, that implies my GND and 12v Constant
are good, so I dont think its a ground issue. It seems SPECIFICALLY
tied to the 12v Turn Signal Wire. That is the common denominator between
the front and back lights.. the signal wire that goes when the turn signals
are triggered appears to not be sending juice.

Come to think of it, Previous owner complained about turn signals and the
headlight not work properly. The stator was disconnected (!!) which caused
the headlight relay not to trigger, and the turn signals were wired all wrong.

I pulled em off a few months ago and totally forgot about that.
Im thinkin maybe the flasher on the bike has gone bad? I have ordered the
EP34 flasher listed above and I will install in when it arrives. That way I can
run my LED bulbs and it will also rule out the flasher from the equation.

Do you have a meter or test light?

I would find the wire color in the diagram, trace it down and see where the juice is or isn't. The wire should be on the flasher plug, but may also be routed through the junction box.

The spade terminals in the plugs can loosen up and cause dead circuits. Had to tighten mine up. Sometimes you can wiggle test wires while the item is turned on, find the loose wire that way.

Three wires on the flasher:

Orange- 12v from flasher to turn sig switch
Orange/Green- 12v from the ignition switch (shown between the other two wires)
Black/Yellow- ground, ties in all over the bike

So if your flasher is bad, with key on, at least the orange/green wire should have 12v on it.

it looks to me like from the ign switch, an O/G wire feeds 12v to the flasher relay. from there it goes to the turn signal switch via an Orange wire (turn sig side), and hazard switch via O/G wire. from them switches, to the bulbs, then ground.

looks like the 12v feed comes thru the 30A fuse in junction box to the ign switch via a white wire. wondering if ign switch needs cleaning/replacement.

what happens if you turn the switch all the way to right? I think this position is supposed to allow parking lights/hazards to work.

Oops, was editing and didn't see your post.

That's a good point and should be a good test. You might have to push the key in, then turn to 'park'. The switch is marked though.

Assuming the previous owner hasn't changed all this routing. In which case ... Punt! .. and regroup.

Alright i have an update guys.

Got the EP34 flasher in the mail yesterday and went to the junction box to put it in. Strangely enough, the flasher that was on the junction box WAS an EP34 already. However, the bottom of it was covered in what looked like rust and corrosion.

The cable appeared to be in pretty good condition though and when I plugged in the new flasher and turned the key, all my turn signals were working properly.

Looks like the problem was indeed the flasher. After gettin them functioning, i pulled off the two wire signals i hsd mounted on the bsck temporarily and swapped em with 3 wires to serve as running lights and inserted the LED bulbs. Tested again and everything works great.

Something i had not taken note of previously is that my bike has a self cancelation unit next to the flasher relay. If they turn out to be annoying i may bypass it at a later time.

Thank you for your help on this one guys.

I was right!!

Sorry, doesn't happen often.

Let's pull some theory out my rear end: the flashers job is to open and close a circuit. I'm guessing your old flasher was stuck in such a way that it passed current through.

I know that relays can weld themselves shut... Happened with my sister's car - things were going wonky and a new headlight(?) relay fixed it lol
