OK...how the hell do I get the blinker to work again after changing it. I've googled everything and tried everything and it still won't work.

I cleared the code. Then turn the right blinker on for 2 blinks. Turn the left blinker on for 2 blinks. Turn the right on for 10 blinks. then cycle the ignition. Did not work

I turned the flashers on for 2 min the cycled the ignition. did not work.

It's a 2023 Low Rider. My understanding is it doesn't have a fuse box or a turn signal module. It's all controlled from the BCM.

I'm like....2 more tries away from taking it to Harley and saying FIX THIS SHIT.

It stopped working Monday on the way back. Right blinker just flashes like crazy and rear one don't work. so I got a new bulb and put it in and still nothing. It's not LED

All that looks fine. Also why they make it such a PITA to remove the battery? Lookalike I gotta take the whole damn rear shock out. It was working fine all weekend then started it up Monday and it don’t work. Stupid shit like this pisses me off more than something majorly mechanical.

the old one didn’t even look blown which also worries me.

That would be the correct behavior under stated circumstances.

Right Rear Turn Signal Output Open

Purple is Left TS
Brown is Right TS

Gotta be a broke/loose brown wire on the way to the rear TS. Try eliminating where it isn't by checking for output on the brown wire in the rear fender plug.
If it's there, issue is in the fender.
If it's not there, issue is in the harness going forward.

Did you by chance put the bulb in correctly? I’ve come across numerous people who are not aware that dual filament bulbs are keyed with different depth posts on them where they’re only supposed to go in one way. If you call upon your inner gorilla you can end up forcing it in the wrong way without knowing it

If that involves taking the fender off or removing parts that don't simply pop off....F that shit. I'll take it in.

It's a single filament so it goes in pretty easy.
