'09 Ultra. Everything else is working on the stereo but the AM/FM radio. One close channel gets very static minimal signal. I borrowed another antenna and plugged it into the back of the radio and it work perfectly which of course points to a short in the antenna wire.

I'm fairly certain that the radio antenna is the right side. Check all those connections, with radio on and no luck. Played with visible parts of the cable down to under the seat and still no luck. Oddly, noticed the the antenna cable from the back antenna forward, joins into a bundle in the tour pack then goes below the top of the frame before the battery area, toward the fuse box area instead of running straight along the top frame, under the tank and into the front fairing area. So I can follow the trip once it goes down, not sure exactly how it gets across. On one hand, the easiest fix is probably just run a new antenna line under the tank and across to the tour pack. But I'd like to know where and how this short is occurring.

Any help is greatly appreciated. Thanks!

 

it's routed through the main harness in 1 piece from the back of the radio, through the fairing, under the tank, and into the tour-pak. I thought on mine when I pulled it apart that there was a connection just inside the front of the tour-pak but I could be wrong

 

I think the radio antenna is is on the left side.Also I think the stock antennas are marked at the base of the masts...AM/FM,CB.
Locate the radio antenna then trace the wire back,probly a bad connection somewhere.

 

The AM/FM antenna is on the bike's left side. Check the connection inside the tour pak: remove pouch; then remove tour pak liner; and, you'll see the antenna connection on the bottom/left side.

Thanks. I know which antenna it is. The odd part is it doesn't appear to go through the main harness all the way to the back. As I said, when following forward of the tour pack, it dips down toward the fusebox before somehow ending up front in the fairing. Is that where the main harness goes from under the tank?

 

Yes,if u pull the tank there is a good size plastic conduit going up the top of the frame.

 

Got it, thanks. I'll pull it this w/e and follow it down.

Thanks for the help all.

 

Check the antenna cable connector at the radio. (maybe you have) It is the weak part of the system.

 

did you ever find the problem? My 2010 Ultra is doing the same thing

 

We got caught in a rain storm last summer and since then we have absolutely no sound out of speakers, all functions on the radio seem to work. We do not even get static. Antenna is connected. Does anyone have any idea what the problem may be? I checked the fuses and they are okay also. It is a Harmon Kardon radio.

Thanks for any help.
