2010 road king, installed FBI stretch fender with LED tag and turn signals. Plugged into stock wiring harness. I wanted more lightage back there at night so I installed a Kuryakyn REAR RUN-TURN-BRAKE CONTROLLER 5497. It plugged inline with the rear light factory wiring harness. It works the lights correctly. However, when I turn the key to run, the rear bag speakers buzz. I noticed that my friend had wired my hogg tune amp power lead into one of the wires in the factory wiring harness.
when I unplug the amp lead, the buzz stops.
How can I stop the buzzing?

Thanks in advance

 

which wire doing what did he have plugged into the harness?
m
was it a ground a power??

 

Check your grounds clean them put some dielectric grease on them ... and any thing you did new ... normally its signal wires running close to power wires...


shielded wires work great too.


if you check and redo all your power connections and it still buzzes ... alternator whine is what we called it in the cars with aftermarket stereos ......

 

Thanks , I'll look into it

 

wish I would have read this thread sooner, added speakers to the bags with second amp, and ta-da buzzing in the rear speakers off the second amp, long story short after another $300 and pulling lots of hair out, and MANY THANKS TO GANN, and YOOPERHOG for their patience dealing with me on the many calls and text, I found this thread and removed the aftermarket RTB module and no more buzz.

 

I had the same problem with my bag speakers and Ciro Bag Lights. Not sure if it was the Amp, or the LED module for the CIRO bag blades, but when I unplugged the module, the buzzing went away. So I wrapped the module with some aluminum tape that I had laying around (Not thinking it would actually work since someone already mentioned they had no luck with aluminum foil), and voila! NO BUZZING! I added an extra layer of electric tape too, It's pretty ghetto but it solved my problem.

The only thing I touched other than that was the ground to the amp. I was originally going to mess with the ground, but decided to try the aluminum tape thing first...so all I practically did was disconnect and reconnect that wire.
