radio volume 1985 GL1200LTD

Postby Akron331pres » Sun May 04, 2014 8:34 pm



I have a 1985 GL1200LTD. The radio volume works fine with the headsets, but when I switch to the speakers there is very little to no volume. Also the self-canceling turn signals do not self-cancel.

I had a similar problem a long time ago ...

Under the left glove box unit, behind the CB there are several ( 3 ? ) grey boxes that are all a part of the radio..

One of them controls the speaker volume (but NOT the headphone volume ) and it works in conjunction with the speedometer: higher speed, louder volume .

There is no obvious way of checking this unit except by replacement ..... although sometimes just un-plugging and re-plugging fixes the faulty connections.

When I put a working one in there... radio speakers and earphones both worked well..

You need a "friend " with a similar machine who is willing to switch parts with you ...

and then comes the REALLy hard part, if thats the problem ... finding a working grey unit without paying $100...

I also had that same issue. I thought it was amp related. Ended up being the Auto Volume Control Unit. The one located in the left side of the fairing. Remove the 'glove box' on the left side, look for the 5-pin jacks that are plugged into the AVC unit. Unplug them from the unit and plug them into each other. (one is male and the other is female) This bypasses the AVC unit. If the volume is better in the speakers the AVC is bad. I just left mine unplugged and adjust the volume as needed. *cheaper than locating and buying another one. Hope this works for you.

Was it the Auto Volume Control? Or was it something else?
