MG MGB Technical - Direction Indicators

Hi Everybody

I have recently fitted a new indicator module to my 1972 MGB and is quieter than the old one.
It is the one with 2 connections.
Is there a way of making it more audible by attaching some device to the wiring.
Thanks

"quieter" "more audible" I have been driving my B for a couple of years now and I haven't heard a single sound out of my directional when it is on.

Some time ago I had swapped my turn signal module for an electronic unit. Although it has been
working perfectly, it is very quiet. This wouldn't be so bad - if only the turn signal indicators on the
dash were not located (for me) exactly behind the rim of the steering wheel, and at the exact places
where I normally place my hands while driving.

Over time, I have been casually sizing up the options whenever I visit parts sources. Here are a few
of my possible solutions that I am contemplating.

There are traditional (non-electronic) electro-mechanical modules which are specifically made to be
louder. These are heavy-duty units and are probably made for truck (lorry) applications. Although
I would like to stay with an electronic design, this may be the easiest and most elegant solution for
most folks.

Add-on "beeper" units can be had at some motorcycle accessories shops - but these are probably
too loud for an auto application.

A miniature12V beeper can be had at most electronics parts stores. I have not determined how to
wire in one of these things so that it would be active with either turn signal (...two beepers, one for
each signal indicator circuit?). The hassle of this may not be worth the effort.

In the US, the module is located behind the passenger (starboard) side of the dash and is mounted
deep inside, on the bulkhead. This is far away from the driver, and the sound is also muffled by all the
steel, foam and plastic comprising the dash itself. Merely relocating the unit to the driver's side (port),
say, near one of the heater control knobs (on an "Abington" Pillow dash), or just behind the radio on
the driver's side, may make it easier to hear.

Peter,
I had the same issue with the inaudible sound level of the turn signal indicator on my 1980 MGB. Some one from this board recommended the IDEAL Turn Signal Flasher Part number 577 (12 volt). I purchased it from a national auto parts chain call NAPA here in the USA. The click volume is 3-4 times that of the original unit. If you can find one I think it will solve you problem.

Danny,

I think if you wired the beeper to the same wire that feeds the flasher, you would get a beep for each flash, regardless of direction.

Any old 12v buzzer or beeper between the light-green/brown on the flasher unit and ground.

Today, I connected a 12v beeper to the flasher unit (and ground) and either way I tried wiring it,
the beeper remains "on" at all times. Here's what happened:

Light green & brown wire = beeper is continuously "on" when the direction switch is "off"
...but beeps intermittantly when direction switch is "on" in
either direction (left, or right).

Green wire = beeper is continuously "on", irregardless of direction switch position (left, right, off).

...hmmm...
Daniel Wong

Aaaargh, you're right. When the turn signals are off there is 12v both sides of the turn flasher, which is why the lights light as soon as you move the stalk and then go off when the flasher clicks for the first time. Try connecting it *across* the flasher i.e. to the green and light-green/brown wires. That way it should only sound when the turn flasher has operated i.e. in anti-phase to the lights (in theory...).
