You have a can bus bike. That means it basically passes info through the wires and they are more sensitive than previous efi systems. You didn’t mention if you used plug in inserts for your LEDs or if you cut and spliced wires.

If you cut and spliced wires, you are not supposed to do that on a can bus system (kinda like fiber optic cable).

If you used plug in ones you need a modulator box. Buy one and plug it in. It will probably fix your problem.

crap i did cut and splice is there anything I can do?like add a load equalizer to each one

i Just looked it up, they sell load equalizers for the canbus bikes, If it works will the lights go off or do I need to reset the codes

They might go off with one of those load equalizers (that's the term I was thinking off). In the future don't cut the wires. De-pin them or solder a good connection. Here is some more info for future thought

The first thing you should do is look up the codes and see what you are dealing with.

Save yourself the time. They are all a direct result from the splices in the wires and from the fact that the LEDs show low voltage making your ecm think the bulbs are out or your wire is disconnected

Here is a link to the ecm codes

[hardleyableson1996]

Yeah all the codes came back to the turn signals circuits being open or relating to the turn signals,I think the equalizers made for the canbus will fix it we'll see in 3 days

You think I can risk riding it for 2 days while I wait for those equalizers?

You’ll be fine
