1977 RD400 LED issue. Flasher relay won't quit clicking.

Hey everyone, love to hear your thoughts on this. So I changed out the indicators and brake light for LEDs. I chose not to you use resistors and installed a new flasher from DCC. Works great, except that the flasher clicks nonstop as soon as the key is turned. I had to cut the original plug for the flasher and wired in new flags for the flasher and used a wire nut on the self-cancel wire. Basically following the tutorial in the tech library from a 2-stroke forum. Since I've noticed the clicking I've redone the wiring with crimper and weather proof connectors and even tried a new flasher from autozone, a ep34 I think, and tried the ground wire in a few different places including the baterry terminal and it still has a steady click. Any ideas of what could cause this? Also during this I somehow managed to blow the bulb on my headlight, it's a 35w H4. Checked the fuses and they seem good.with this I have a few other questions, I plan on changing out the H4 for a trucklite led headlight and I'm wondering if I need to do anything to bolster the electrical system for all the extra juice not being used by the leds, like maybe different fuses or resistors or maybe something else. Any help from you guys would be a huge help to me. Look forward to hearing back soon!
 
Any luck?. I'm having the same issue. I know there are some electrical gurus on here that know there stuff... hopefully get this figured out soon... I'm using the same 3 prong flasher relay you are with a "positive" "negative" and "lamp" connections maybe I have it hooked up wrong.. someone.on here should be able to tell us exactly which wires are supposed to go to those.?? No?
 
I had the same same problem with Chinese relays off ebay, took 4 before I finally got a working one. Try plugging your old relay in and if the indicators stay on and dont flash its your relay thats faulty.
 
The old relays wont work at all with leds unless you use resistors
I bought a brand new one from auto zone and it works, just flashes always
 
If you plug the old relay in it will either flash very rapidly or look like its permenantly on. Thats why on the that type of ralay you need resistors to use them correctly it fools the relay into thinking there is enough current draw for it to work correctly, otherwise it thinks a bulb has blow and makes them flash rapidly.
 
Yes. I tried the old flasher with resistors first with no luck so I went out and bought the ep34 led flasher relay a lot of people are using and it works but it clicks constantly. When the switch is left the left lights work perfectly, when the switch is right the right lights work perfectly. When the switch is un the center nit turn signals are on but the relay still clicks non stop. I think I have one wire going to the wrong spot so the flasher relay is always getting "power"? I don't know. With so many people using universal generic led flasher relays there has got to be a right and wrong way to do it and I obviously have it wrong... if someone could post exactly where they used the 3 prongs and where they went that would be a huge help. Thanks.
