Different radio problem

Just discovered that the left hand speakers on my radio/CD player does not work. This is the bike I just bought. I checked the balance, and if I go to 10 Left, there is absolute silence. Both front and rear speakers does not work. Any quick solutions? Also, I got 2 alarm remotes, and only 1 of them work. The remote blinks, but not the bike, so it is not a dead battery. Are they easy to program?

Current rides:
2003 BMW 1200 LT (bought in 2006)

Past rides:
97 Kawasaki ZX11(bought new in 1997, sadly sold in September 2014)
89 Honda Hurricane (sold)
88 Honda Hurricane (traded on an SUV)
86 Kawasaki 1000R (stolen but recovered)
84 Honda 750F (traded on 1000R)

The radio could be a wiring issue. Check for loose connections under the left side of the stingray (opposite the fuel filler) and at the back of the radio itself. The first requires removing the left side tupperware, and the second both sides and the entire radio stingray. Other than that, sometime the radio's internal amplifier goes bad.

As for the alarm remote, there is a programming wire under the seat and a procedure for authorizing a new remote. You need both remotes to do this. The procedure is in our Technical section (link at the top right of every page). I don't remember exactly where it is stored though.

I had a simlar problem (I believe) with my stereo system. I was getting distorted sound at higher volumes since I bought the bike (new). When I took it in for my first servce, I asked them to look into it and they found that my right side speakers were toast - they replaced them under warranty.

In addition to the help files here, if you have the owners manual for the security system, the procedure should be in there for re-sync-ing a remote (I recall there being something about if a remote's button is pressed more than 250 times while out of range from the bike, it will not work util the re-sync is done).

IMO, the easiest place to start...

The easiest way to rule out whether it's a blown speaker or a 1/2 blown amp is to connect the left rear speaker to the right rear speaker lead. If you hear sound, then the speaker is OK and the left side of the amp is blown, or you have a short.
  • Lift the rider's seat
  • Remove the passenger's seat (2 Allen screws)
  • Disconnect the barrel connector that goes to the tour trunk. (There's two of them. You want the one that runs left to right, parallel to the front of the trunk. To ensure you have the correct connector, turn on the radio. You should now have no sound out of the right speaker.)
  • Using the color chart below, find the correct pins and use two little jumper wires to connect the speakers leads coming FROM the amp, and connect them to the leads that are going TO the left speaker. (SO you want Blue/Red to Yellow/Blue , and Blue/Grey to Yellow.
  • Turn on the radio.
  • If you hear sound, your left speaker is good and the trouble is in the amp or wiring coming to that point. Most likely the amp.
  • No sound = blown speaker. And most likely the front one is blown too.
You can experiment with the balance control to ensure your jumping the leads correctly. I hope all of this makes sense. Good luck.

Yellow/Blue: Left +
Yellow: Left

Blue/Red - Right

Blue/Grey - Right

Joe, you're a farkling genius. My left channel is also out, but I've been dreading pulling the tupperware, etc. to get to the radio in my 100 degree garage.

BTW my '02 radio was replaced under warranty in '04 just as the warranty was expiring. I just found out that the replacement part is covered by a 2 year warranty independent of the bike's original coverage.

Nope. I just know a little about audio troubleshooting.

Thanks for the kind words just the same.

After checking all of my wires, I'm sure its the internal amp that I fried on my radio. I've got a line on a replacement unit from a scrapyard but want to make sure I'm getting the right unit. The radio unit itself is the CD player unit on my 02 LT right? It's not the panel with the buttons on the dash. Right?

Yes, the main radio (amp, etc.) is in the same case as the single CD player (or cassette player for earlier bikes). The buttons are just a remote control panel.

Different radio problem

I recently had a similar problem... and have only partially fixed it. Both of my front speakers went out at the same time on my 03 LT. Seemed likely not to be simultaneous speaker problems, and other threads pointed to bad connections under the left tupperware. I found the connector for the front speakers and everything looked good to me. Cleaned the connectors really good but no change. Put it all back together because I'm still under warranty. I let the dealer troubleshoot it and they said it was a bad radio/amp. They had one in stock, replaced it and said everything was good. When I got on the bike to take her home, I thought I should do my own final inspection. Right front was fine, but when I moved the balance to the left... nothing!!! Since I can live with it for a while, they agreed to provide warranty work on the next visit and the tupperware comes off. I have no idea what's going on. Maybe another bad amp, maybe they bent a pin putting the connector back together??? I hate doing tupperware worse than living w/o a left front because I use a separate MP3 most of the time anyway. Still puzzled???
