Just had to post this again - has helpedimmensely - andONLY $18.

Mine is mounted inconspicuously on the back right side of the fairing. You'd never notice it. The other side is 100% black - no sticker.

Had a serious problem with engine noise using the external AUX input for my MP3 player - not anymore with this thing in series.

Let me know if it helps you out!!!

HIGHLY RECOMMENDED. WILL BOOST YOUR SIGNAL TOO - THINK IT IS LIKE 1.3:1.

S/N RATIO IS AMAZING NOW.

'05 ULTRA WITH EXTERNAL/AUX HD MP3 PLAYER.

 

Been using those for years in the car audio world. Those come with L and R RCA plugs and not mini-jacks......where does that plug in?

 

unplug your ipod or other player from the Aux jack on the front of the HK Radio
Plug in the filter
Plug your ipod or other playing into the other jack on the filter

same as the older ones for cars, just different plugs

 

You can buy the same thing in any electronics shop (i.e. Radio Shack or Wholesaler) for about 10 bucks. They've been around for decades.

 

After 15 years as a professional installer, install manager & install trainer, MHO is that while these products have a place they should not be used.

A noise suppressor is like a band-aid on a broken leg, it does not solve the problem. 99% of noise in a 12v application comes from improper grounding. Fixing all of the ground points is the proper method, and costs nothing but time.

In the case of a headlight modulator or similar, this is called "irradiated noise" This can be solved by moving the offensive product or wire or wrapping the head unit in Mu metal.

Fix the problem properly. You will have better sound quality & feel like a champion!

Scanner,

I'm not being a smart ***, but could you help me troubleshoot where I might look for my grounding problems? I run a long cable from the front of the radio all the way back to the tour pack. When using the iPod alone it's great. However, when using the iPod while it's plugged into the 12v outlet I pick up whine that rises and falls with engine speed. The 12v plugs are wired into the courtesy light which is mounted to the inside of the tourpack lid. It's wired directly to the battery and is always hot. The light is operated by a mercury switch and comes on when the lid is opened. The ground is wired directly to the metal plate on the bottom of the inside of the tourpack where the CB antenna is grounded. Where should I start?

Also, in my truck (2000 Durango) with stock factory radio, I sometimes pick up whine and noise too. However it's only when using the AM radio and trying to listen to ball games. Is that alternator whine? If so, why is it only present on AM?

Thanks

 

Without being there to diagnose the problem hands on, I will do my best to give you some ideas.

1. You may be picking up something through the ipod input wire to the front of the deck. Being as it has very little shielding and you are running it a long way past many eletrical items, I wouldn't rule out this possibility. Probability of this being the problem is very remote, especially because your description sounds like a grounding issue, but still could be the cause of the noise. Also, from your description, the problem is not there when you do not have the ipod plugged in.

2. Don't you have a fairing mounted lighter/accesory plug in your Ultra? (All I have to go by for this is my '08SG) If not, the wires may be up in the fairing for something like this, so I'd recommend relocation of the ipod power source up front. The reasons I mention this are many.
A. Better to have the ipod up front for ease of operation, especially while riding.
B. Potentially "cleaner" power souce up front with dedicated wiring for an accessory.
C. Good grounding cluster up front on the fork, which has very low resistance to the ground point of the battery. A higher resistance to a good ground point like that at the battery terminal will often be the cause of noise, especially "engine whine"
D. Getting away from long wire runs in a 12v application is always good. If you can keep wires short, do it.

3. If you like your set up and don't want to move your power source, then try this. Look under the seat near the battery for some of the factory pre-wired accesory leads. Use this for power if availible. If not, then run a fused power wire directly to the positive terminal of your battery. Here's the big issue, and it's the first thing you should do, if you choose not to run a seperate power source for the ipod. Run a wire to the ground point under the seat where many grounds are (make sure you use some type of permanent connector, not just wrap the wire around a screw) the run the other end of the ground wire to the metal plate and screw it onto it. Again, use a good connector and either use an exisiting screw or make a new hole with a new screw. Make sure the metel part of the connector makes good metal to metal contact with the metal base plate. If there is any paint in the way, scrape it off. If you do this, not only should your whine go away, but you should also have improved reception woth your CB.

4. As for the Durango, what? Your explanation says you only get it when you listen to ball games. You don't hear it if your change the station and listen to talk radio? (All on AM of course) If you just get it on one am station and not the others, then it is more than likely the station, or the equipment being used to broadcast the game. If it's all AM stations, then these issues are li

Look under the seat near the battery for some of the factory pre-wired accesory leads. Use this for power if availible. If not, then run a fused power wire directly to the positive terminal of your battery. (In other words avoid using the tour pack light to tap into, even though it's wired directly to the battery. That I can do!) Here's the big issue, and it's the first thing you should do, if you choose not to run a seperate power source for the ipod.

Good luck trying to find the source(s).

I just thought an $18 fix was short and sweet.

HAS WOrKED FOR ME FOR OVER A YEAR WITHOUT A GLITCH!!!!!

 

You're right. But the fix he suggested (hard wire to the battery, and a clean direct ground) are simple enough for a guy like me. However, if those do not remedy the issue, I'll probably end up buying one of those filter gizmos before my Summer trip. I can appreciate cleaning something up and making it work right. But I'm not going to tear the bike apart either. I do appreciate his professional input though.
