The successsful "non-invasive" two buzzer mod for the GT200 that I previously posted, prompted me to look at a possibly simpler mod.

After looking at the electrical diagram, I found that the connector for the alarm cicuit offered the possibility of another "non-invasive" adaptation. This time using two diodes and one buzzer. (per addicted)

Removing the left hand inspection cover, will reveal three connectors .
The six point connector is the object you want. The three points of interest are the pink wire, the black wire and the white wire with blue tracer.

The black is the ground, the pink and white/blue are the turn signal wires.

The cathodes of the two diodes are common to the red wire of the buzzer.
The anodes go to the pink and white/blue points of the connector.
The black lead of the buzzer goes to the black lead of the connector.

I epoxied the two diodes to the top of the buzzer case, soldered the two cathodes to the red buzzer lead.

I then stripped 1/2 inch insulation from the black buzzer lead, folded and soldered it, to make it stiffer.

This gave me three male points to insert into the three female points of the connector. (sounds sexy, eh?? menage a trois!)

I then foam taped the assembly to the inside of the cavity.

Works like a hot damn and again, is "non-invasive".

This should work for the GTS as well.
A plus is if you hook up the alarm, you will have a howling buzzer to add to the noise.

Parts list:

2 - 1N4001 diodes (or any general purpose diode) (Radio Shack)
1 - 273-059 Piezo Buzzer (Radio Shack)
Double sided foam tape.
Lepages 5 minute epoxy cement (or any other that is available)

just done this to my GTs and apart from having to learn how to solder it was a complete doddle and works brilliantly, i used a 90db buzzer with the view that if it can always put some tape over it to reduce the output if it's too noisy.

overall an easy cheap and extremely effective modification and i reccomend it to everyone, well done Clap emoticon Clap emoticon Clap emoticon

Turn Sig's Revisited
I had mine installed yesterday using the six point connector. Works great. Thanks for the tip

Note
I finally had time to do this modification this evening. Only thing that was a little frustrating for me was not knowing that a "diode" has distinct ends: anode and cathode (hence the reference in the instructional post that said "soldered the two cathodes to the red buzzer lead"). As it would happen, I used the anode end on one side, so initially it did not work. Once I realized that I had one of them installed backwards, I re-soldered it and it worked great! I also have never done any soldering so that was fun also.

Thanks so much for posting this fairly quick and easy modification. I believe it really adds to the bikes safety.

True Story:


Radio Shack kid: "Can I help you?"

Me: "Yes, where do you have diodes?"

RSk: "What are diodes?"

Me: "Electronic components."

RSk: "He better help you."

2nd RSk: "Can I help you?"

Me: "Yes, where do you have diodes?"

2nd RSk: "What are diodes?"

Me: "Electronic components."

2nd RSk: "She better help you."

Me: "Do you have diodes?"

Manager to RSk: "Downstairs in the drawers."

2nd RSk: "Can I borrow that list?"


Always always ALWAYS print out the part numbers you'll need.

:roll



Edit: IT WORKS !!! I can even hear it on the highway (90dB buzzer), with a fullface helmet , up to about 60mph!
