I have seen a few really good guides on how people did things to their bikes... well, I was working on mine tonight to do a few things and I thought I would document what I did so that if anyone else wants to know how to do it, they can.
So. The infamous speaker of deaf... the one that screams bloody murder when you use the turn signal.
Since I was getting into the guts of my bike for a different reason (see the post on the dash switch) I figured I will slay the beast while I was in the neighborhood.
The first thing you need to do is get into the dash. there are several screws located around the unit that you take out and the entire thing more or less falls apart. I found that I didn't really need to force anything. If you have to "force" it, check to make sure you didn't miss any, as sometimes, they are well hidden.
Now, I don't know about the rest of you, but my innards looked like my small intestines. Jumbled, and in one big bulge.
I turned the key on, and hit the signal and at once I heard the speaker scream for it's life. VERY VERY CAREFULLY did I proceed.
Please note: I do have experience dealing with electronics, therefor, I know what is safe to touch and what is not. If you are in any way not knowing exactly what you are doing, then do NOT turn the power on. The reason I am writing this guide is so you don't HAVE to.
The hunt was on!
Then... when all hope was lost, our mighty knight saw a glimmer of hope on the horizon. As he rode his mighty charger forward, he came at last... face to face with the mighty beast!
I have no idea if this little box is standard for all bikes, all I know was that this little thing was emitting the ear piercing sound that was causing windows to crack.
I then, happily, killed the power. The beast went silent. Victory was about to be mine!
The cover just slides off, it was pretty simple.
Now, here's the deal - again - I have no idea if that little box and it's innards are standard for the XB500, or any other model... however, if you are looking at your bike and for some reason you can't find that box, what you are looking for this a board mounted speaker.
Almost every speaker I have ever seen in my life of this nature looks like these, so if you don't find that little box, try looking for the speaker itself.
Once you have located your little harpy, it's time to gag it! The thing is, you don't want to mute it completely... it is a good idea to have some kind of audio signal when your signal lights are on, if for nothing else to remind you that you have it indeed on.
To lower the sound, all you need to do is cover the hole. In my case, a couple of little square bits of masking tape did the trick quite nicely. It could still be heard, but didn't make all the neighborhood cats run in terror.
Choose whatever method of gag you like.
Now remember - the speaker is actually out in the open. You are going to be putting it BACK in the dash, so if it seems a little loud, don't forget that it will be covered yet again by the hardware...
You may want to just play around and use trial and error, but 2 or 3 layers of masking tape should be fine.
Before you put the casing back on, you may want to take note that their are holes in the casing. I would not completely recommend covering them all, because besides allowing sound to pass through, there could possibily be another reason, like heat and air flow - it's doubtful, but better safe than sorry.
When I put the casing back on, and tested it, I found that the casing actually amplified the the sound.Go figure. By only blocking the side hole, it significantly reduced it back to the volume I wanted.
Once the casing was put back on, I was done. Ready to be put back in the spot I pulled it out of and put the bike back together.
So the bottom line and things to make note of.
First of all, you may NOT have to cover the speaker, but just cover the holes in the casing.
I seriously doubt that any harm will happen if you do.
If you don't have alot of experience handling circuit boards, I highly recommend just taping up the casing, Assuming it matches the one in my bike.
Don't worry about getting it EXACT... I mean, your just muting a speaker, it's not rocket science. Sound needs to move through air to get to your ear, block the air and sound doesn't move as easily. (unless you put your ear against it directly - but why would you do that?)
Good luck, and safe driving.
