    Very quiet Turn Indicator

    Gentlmen,
    I have the Turn Indictor flasher unit that came with the car when I bought it. It works exactly as it should, however the Clack, Clack, Clack sounds is not really audible when I drive. It's fine when stationary and with the bonnet open, which is not much help, but once driving with the top down, I cannot hear it at all. I have no idea how it sounds with the soft top or Hard top on, as I have not drvien mu car like that yet.

    It is correctly mounted in the "C" shaped spring, which is firmly mounted into the firewall metal with the firewall deadening removed from the contact area.
    Modern cars have this under the dash, rather than in the engine bay, which makes a lot of sense.

    Has anyone found a solution other than to move the fasher unit inside the car?

    Regards

    Jeff,

    I find the big blinking red light to be visible enough that the sound is not necessary for me. I guess you could pull the flasher harness back into the car and mount it under the dash. I wonder if you would hear it with the top down.

    Hi Garry,
    Yes the flashing Red light is there, but I like the reassurance that the indicatro lights are actually on, so the addtion of sound is very reassuring for me.
    I once read that an extra load flasher was available, but cannot recollect where I read that or even when.

    The other option (that just came to mind) could be to mount a 12v relay under the dash connected in sefies with the red light. Standard Relays make a quite load click, and if left unconnected to anything esle, could make an inexpensive and easy fix. I'll try that and report back.
    regards
    Jeff

    Jeff, I'm interested in how your relay experiment turns out.

    I switched to LED turn signals some time ago and so had to swap out the flasher for a solid state one that would handle the LED bulbs. I do miss the clicking noise though.

    If it really bothers you, it would be easy enough to wire a small buzzer or other noise making device into the circuit. Here's a quick look at what's available through Radio Shack if you can still find one of their stores: https://www.radioshack.com/pages/sea...ndify_q=buzzer

    Yup, there's a large selection of such things from various vendors.

    The problem with choosing such things is that you will need to buy and reject a lot of them. Why? There is no way of knowing what they sound like or how loud they are until you try them.

    For my tastes, there would be less trial and error if one start with a mechanical relay.

    Success. Really easy to do.
    Frank was correct that a standard 12 volt mechanical relay was idea. I ran a wire from the blk/green/white wire at the front of flassher unit, to one side of the relay's activation coil (pin 85) and from Pin 86 to a suitably ground point. The relay draws such a tiny amount of current that it makes no differecne to the turn indicator lights at all.
    Secured the relay to a suitable location under the dash, and that's it.
    Nice and easy, simple to remove if you want to, works like a charm, and if you have a spare relay lying around, the cost is Zero.
