    Posted: 17 Dec 2009 at 22:34
About 12 months ago my indicator relay packed up and my indicators refused to flash. I had already decided that I was going to replace my indicators at some point with LED units so I replaced my relay with one that was LED compatible.

That was when the troubles all started, the LED relay was absolutely silent in its operation, hence no audible indication (Pardon the pun) that my indicator was flashing.

Being a seasoned biker of some 20 years plus I am well versed in what happens when a rider forgets to cancel the indicator, sorry for the image but this happens quite a lot.



I did not want to become one of those statistics so I decided to make a minor modification to my indicator circuit, here goes:

Firstly I went to Maplins Electronics or you can use any good electrical shop, or even Flea Bay and I bought one of these.

Buzzer specs are:
Type Voltage Impedance Frequency Output at 30 CM
12V 9 – 20V 480 Ohms 400 Hz 75 dB
Make sure you have some way of attaching it to the indicator circuit, it could be by Scotch Locks (Arggghhh!!) or by solder (Lovely!!).

Remove the front fairing to gain access to the wiring loom.



Unhook the LED indicator relay from its mount so that you can access the loom easily.



IMPORTANT!! If you have a diode in the indicator circuit then the buzzer must be fitted between the diode and the LED relay. If you add the buzzer to the circuit outside of this area it will not work correctly.

Best to attach the buzzer to the indicator loom as close to the relay as possible.

For those using Scotch Locks follow this:

Pop down to your local Auto store and buy yourself a soldering iron, some solder and a book on how to solder.

For all who do not know what a Scotch Lock connector is:



For those soldering follow this:

Strip back a piece of the insulation about 10mm on each wire.

Attach the wires as so:

Black wire on the buzzer connects to the blue/black at the LED relay connector.
Red wire on the buzzer connects to the green at the LED relay connector.

Just twist them on to the main loom for now.



Now test that when you indicate left and right that the buzzer sounds.

OK, if it works well than you need to solder the connections and make good the loom insulation.

If it doesn’t work then retrace your previous steps and make sure you have followed the instructions. If all is correct then reverse the electrical connections you just made, it may be that the manufacturer of the buzzer has connected the wires differently internally.

Locating the buzzer

I tried various methods and positions of locating the buzzer and decided upon this method and location (See images below). My reason for this was that the sound of the buzzer was distorted when it was connected to a hard surface, distorted even further when the vibrations from the engine were encountered.

Small cable tie threaded through the buzzer



Buzzer cable tied to the loom to avoid vibrations





You will need to decide what’s best for you on the location and connection method.

However, I would strongly recommend that you stay away from Scotch locks as it will inevitably end in grief somewhere along the line.

Rebuild the bike in reverse order and go for at least a 2 hour road test, tell the wife it’s mandatory. LOL

I know that a lot of you will be saying 'No fecking way am I fitting a buzzer' well that's your choice. All I can say is that a huge percentage of motorcycle accidents happen at junctions and many are caused by the rider leaving the indicator on.

Hope this helps save some lives!!

Update:

You can now get this on Ebay if the constant buzzes gets to you when indicating to turn at traffic lights etc....

Buy Me Here

Basically it adds in a delay of around 15 flashes before the buzzer starts sounding, you can also buy ones that you can amend the delay time.  Thumbs Up

It scares me when I see riders leaving their indicators on whilst riding down the road, every bike should have to have some audible warning device fitted.  Confused

So I never leave mine on
