I went back through so many posts on this board about the diode fix and came across 2 people that asked the same question I am about to but they had no replies 😂. I couldn’t find an answer and I’m sure someone smarter than me could find it in the archives.

I installed the diode fix because when my left, rear blinker was on, my right one would also blink faintly. It also caused by brake light to flash. My my right rear blinker works as it should as do all the other blinkers.

I install the fix and it still does the same thing. I followed the instructions from Bad Ass Choppers and am pretty certain I followed his instructions but… 😊

You took the orange lead from the indicator and tied it to ground?

If you can, disconnect the indicator light all together. What happens then? Which diodes did you use? Should likely start with a 1Nxxxx number.

The cathode of the diodes (the end with the stripe) must go to the lb wire on the indicator light that has been disconnected from the lb wire that connects the switch to the right signal lights.

like this
the red x is where the wire gets cut

I did ground the orange wire to the green. The diode is attached to the LB wire.

I used this kit : Kuryakyn 4709 Motorcycle LED Lighting Component: Diode Kit Wire Assembly for Metric Motorcycles with Single Turn Signal/Blinker Indicator Light on Dash https://a.co/d/dztXeWa

and the instructions from Bad Ass Choppers:
Read this part carefully…
With the orange and light blue wires cut, strip the insulation from the orange wire coming FROM the dash lights and splice it into the green wire in the harness. This green wire is your bike’s ground and you want to tap this wire into that ground. Once you solder the orange wire into the green, heat shrink the connection or wrap it tightly with electrical tape.
Now you have 3 wires left, 2 coming from the bike (orange and light blue) and the light blue wire coming from the dash lights. You have to decide whether you are using the Kuryakyn premade diode kit or if you are making your own kit.

Quick tip: hide your license plate numbers in pics. Hope you get this diode thing figured out!

The second part of the 1800C indicator fix for leds.
Two wire cuts on the TS indicator.
Ground the TS Indicator to Orange wire.
Now put the diode (arrow pointing up) anode to the TS wires,
Orange wire TS and Light blue TS then both diode Cathode stripe to the TS Indicator bulb.

RECAP: two wires cut from the indicator lamp, Orange wire to Ground.
The indicator lamp wire LB goes to the diode cathode/stripe ends.
The other two wires that were cut go the Anode/Arrow end of the diodes.

You had a problem before and the two extra diodes did not solve it. That's a big clue that your problem lies in the actual turn signal system.
I see that you installed the cheapo Chinese LED turn signals. Were you aware that the running light and turn indicator on those are not on separate circuits? It is the same branch with just a different resistor inline, not even an isolation diode. That causes the turn signal power to cross-bleed into the running light circuit.
If you want to keep these LED lights, the only solution is isolation of the circuits, should be doable with just one diode in each turn signal housing.

I bought this bike about 4 weeks ago and am slowly undoing the previous owners gaffs. These blinkers were on it when I got it but the red lights were in front and amber in back.
Are you saying that if I buy a more suitable pair of blinkers to replace the Chinese LED cheapos, the diode fix should work?

 

[rangers4u]

I can't help with the electric issues, but better check your motor vehicle codes those red fronts may be illegal.

 

[Hans&Feet]

Put the amber lights up front, red lights in the rear.
As mentioned before add two diodes with the Cathode band to each of the led units.

The O and LB wires you are showing in your picture. Are those going to the indicator light or are they connected to the indicator light right now?

Where do the other ends of the LB and O wires you cut go to? Does the dash indicator work as expected?

The kit you pointed out looks like this;

The kit you show has the diodes separate. Not that that matters, but in that case, the red wires would go to the LB and O wires and the blue wire to the LB wire to the indicator. Then the O wire on the indicator is tied to ground, presumably with the black wire. My bet is that if you take the incandescent bulb out of the front, (do you still have incandescent in the front?), your LED will be as bright as the left side. In that case, you are still back feeding, somehow, through the indicator. I'm not sure how, but if you have an ohm meter, put it across the LB and O wires in your picture. If it doesn't read anything, or infinite rather, then put your meter on the diode setting. You should read infinite there as well.

I used the same diode kit in 2004 and followed the same directions of Bareasschoppers and everything is still ok. So check if you didn't do anything wrong. Is your back light oem or also LED?

 

[cgooge27]

Back light is also LED.

 

[cgooge27]

My front headlight and brake lights are also LED. The indicator light works as it should. Here is how the rest of the bike is wired “The Kuryakyn diode kit has 1 blue wire and 2 red wires. You want to solder and heat shrink the 2 red wires from the diode to the orange and light blue wire coming from the bike”.

 

[cgooge27]

Definitely illegal here. They were switched when right after buying it.

 

[cgooge27]

Yep! Switched them right after buying the bike!

Put the amber lights up front, red lights in the rear.
As mentioned before add two diodes with the Cathode band to each of the led units.

 

[fastspek]

Back light is also LED.

Disconnect the back light connectors behind the right side cover and see what happens with the blinkers. There is a LED back light version that also has built-in blinkers.
