Electrical Connection Add-On

[onelostsock]

I have an '06 that I use my Sansa MP3 player(using the AUX setting) thru my headphones for my wife and I regularly and am really annoyed by the alt(?) whine and the revs of the engine also. So I am thinking of buying E.C.'s isolator that is supposed to take care of this problem. Has anyone have first hand knowledge of this add-on and does it do what they advertise? I realize it is only $35 but don't want to spend it if it does not take the majority of the whine/noise out. Thanks for any experiences conveyed.

It depends.

Are you powering the MP3 player from the bike? If so, does the whine and noise go away when you unplug the bike power from the MP3 player and let it run off its internal battery?

If the noise goes away when you unplug the power from the MP3 player, then a ground loop isolator like the EC unit will more than likely fix your problem.

And if you don't feel like paying $35 for Electrical Connection's ground loop isolator, you can buy them on Amazon for around $10: http://www.amazon.com/Mpow-Ground-Isola ... ingdocs-20

My MP3 player is powered by its internal battery.I do get some whine rising and falling with the engine rpm's also but maybe not as pronounced. Is there anything available that would help this?

OK, so you aren't powering the MP3 player from the bike. You could try a ground loop isolator, but I doubt it's going to help in your situation. Try physically moving the MP3 player around on the bike - several things on the bike (especially the coils) put out an awful lot of EMI, and if your relatively low-voltage audio wiring or circuitry is anywhere near it, it will pick up this EMI and you'll hear it as noise that changes pitch with the engine RPM.

W.A.- Thanks for the ideas. I'm not sure I could move the MP3 player really because I tend to change songs, turn it on/off etc while it is in the left hand pocket. Also I do get noise thru the radio thru the headsets too. My wife is not bothered by it much but she has a lot more wind noise than I get. Not sure if that makes sense at all.

EC has two versions, I'd suggest the extra $10 or so for the version that boosts the signal a bit. Isolation alone seems to depress the signal level.
