I tried swapping the stock turn signals for some LED ones, purchased the relay as I've seen I would have hyper flash issues. With the relay plugged in im experiencing a power surge to the main 30 amp battery fuse, even with the key turned off. Tried swapping the terminals and still getting that instant power surge as soon as I put the battery terminal back on. Any suggestions? For now i have the stock relay in but am ofcourse getting hyper flash

Stop! Put the originals back on. Other people have had problems with aftermarket LEDs too. Did you buy them from Husqvarna?

Stop for what reason? Other then can blow a fuse or possibly the relay. I've seen this conversion done successfully so I know it can be, just looking to trouble shoot with someone who has done the same. Thanks anyways
 
If your blowing the main 30 amp fuse, you have a short. I also would recommend to stop and trace back the source of the short. You may want to check the relay and validate it functioning as it should.

I can tell you the factory euro relay desigend for the LED flashers on the duke and 401's is a quality, robust unit and is inexpensive.

With the stock relay in the fuse dosent blow so I'm leaning towards it being a faulty relay (amazon). Will look into ordering the relay you mentioned. Thanks
 
Don't do it, man. Here is a quote from my similar exploits last fall: "I just got back from spending $400 for 5+ hours of troubleshooting at the dealership to correct: Stalling, "quick shifter failure" and various other ECM codes thrown. Husqvarna USA says it was my aftermarket sequential LED turn signals and the aftermarket flasher!!!! They finally replaced the OEM incandescent turn signals and flasher. No codes, no issues. The service manager said, don't change ANYTHING electrical from OEM, not even the wattage of the bulbs. Expensive lesson learned."

I mean, that is just a ridiculous statement. If you don't understand how electricity works fine, don't touch anything with wires. But if your bike is running fine, then you install something and it stops running fine basic troubleshooting would point to the problem being what you just installed.

TST makes a quality relay with clear instructions for what wire is what, you may need to remove the rearrange the pins to make it work with our bikes but the information to do so is online. Another exceptionally simple option is to just wire in resistors with the led signals.

I got quick shifter failure before I ever touched anything electronic. OEM flasher is still in for now with aftermarket signals, waiting on another flasher from another supplier. I guess Husqavarna wouldnt like my other modifications then

Recommend keeping a written log of everything you do that is not cosmetic. Hopefully, that way, when you start having problems you can point back to a specific time and event that you did in order to troubleshoot.
