Another Day of Troubleshooting

[RazeOrion]

Posting again! Finally!

The Good: I determined my turn signal lights to be bad and replaced them. When plugged in and with the bike powered, they light up!

The Bad: They are ALWAYS lit up. I inspected the flasher relay and believe it to be bad, so I have ordered a replacement.


Does anyone know what else may be causing this issue?

Well, a few things:
1) Could be your flasher relay stuck closed, as you suspect, so try the replacement when it arrives.
2) Is your wiring stock? If not, like if you replaced the fuse block or whatever, make sure the wires are going to the right place.
3) Are you using incandescent bulbs everywhere, or are there any LEDs in the mix? I've had an issue where having an incandescent anywhere makes all the LEDs go on.

1.) I'll update on part replacement when it comes in.

2.) Wiring is stock, as far as I'm aware.

3.) All bulbs that are installed are LED lights.

Did you install blocking diodes in the turn signal circuit? They are needed if you run LEDs as your turn signals. There are a bunch of theads on here that go through this and you can buy a kit that you can insert into the wiring of the turn signals

But there is a way to make your own that wires into the pilot light circuit in the headlight bucket. Here is the modification that I did with two diodes, a couple of connectors and some wire:

Original circuit:

Modified circuit:

I remembered overnight that there are a few other things that are required to use LED indicators on these bikes. So, here is the full list just to have it all out there in one spot:

1. You will need to replace the flasher relay with an LED compatible relay. This newer relay will operate with the lower current draw of the replacement LED bulbs.
2. You will need to unplug and remove the auto cancelling relay and replace it with a jumper from the Y/G wire to the B wire in the harness. I did this by wiring up a plug (see photo below).
3. If you put LED bulbs in the pilot box, then you will need to wire in the blocking diodes as I indicated in my previous post. These are required because the original circuit took advantage of an incandescent bulbs ability to pass current in either direction and still light up. LED bulbs can only pass current in one direction, so the circuit needs to be modified to accommodate this.

Here is a picture of what my jumper and wired up blocking diodes look like:

If I gotta do all that, I may just swap back to incandescent bulbs
