LED blinkers constant on after Trail Tech Vapor install

Hey guys

As some of you know I've been resurrecting and rebuilding an '01. Last weekend I tackled the factory dash-ectomy and trail tech vapor replacement. Install took a while but went well. Everything working properly. The P/o installed LED blinkers all the way around. Since I unplugged the dash, the blinkers are now constant on when I signal left or right. Do I need to add a resistor? How do I remedy this condition???

Thanks again, all!

Does it have the correct flasher?? Did they work before?

It worked just fine before the plug to the dash was disconnected. Leads me to believe it was the appropriate flasher.

Not sure about a KLR flasher but: Most older style flashers work by heating up an element inside the flasher and when it gets warm (due to elec current running through it) it breaks the contact. When it cools down the contacts touch again. That causes the flash. When you switch to LED's the amperage is so low it doesn't heat up the element. Sometimes people add resistors to increase the electrical draw. Other times people use an "Electronic flasher". I'd just put in regular bulbs and ride.

If the PO installed an electronic flasher, it would have had to failed in the closed mode at the exact time you unwired the dash. This is not very likely at all.

If the PO wired some bypass resisters to make the original blinker relay flash the low power LEDs, the easiest place to wire the resisters in would be right near where the left and right signal wires connect to the dash turn indicator light. And when you removed the dash, you could have removed the resistors.

I noticed on my 03' , unless my engine is running my flashers fail to work as well.
They work great while traveling , and I guess that's what counts.

That may be a warning to check your battery voltage.

Well I had the whole bike apart this weekend and didn't see any resistors anywhere from the previous owner. All four blinkers are LEDs and they were working properly before the dash was unplugged. So I still have no idea what to do to fix this.

This weekend I tried to add a neutral indicator light back to my dash board. I simply purchased a green led from autozone and hooked it to the old neutral light's wire in the OEM connector. I then grounded the other side of the new led. Won't work. No light. I plugged the old dash back in... Light comes on/off as it should. I'm totally vexed. The ONLY thing I didn't try and thought might possibly work is to run my new ground back to the brown wire ground in the OEM plug. Any suggestions??

The neutral light wire is a "GROUND" wire when the transmission is in neutral and "OPEN" when in gear, so you need to hook the other side of the light to a wire that is "HOT" when the switch is on. If there was a brown wire to the OEM plug, that should do it.

You might want to start with a new "two wire electronic flasher" to solve the problem of the signals not blinking. Take your old flasher to an auto parts store and ask for one like it that is electronic for LEDs.
