Intercom noise

Postby liv2ride007 » Mon Aug 29, 2011 12:01 pm



I have a problem with my intercom making a whining noise. This just recently started to happen. I have not added any new lights or accessories to my 1999 GL 1500. I can listen to the radio or cb and have no whining if the IC volume is turned off. This problem seems to happen on an intermittent basis. Part of the problem seems to be the passenger intercom. My set seems to work all the time but the passenger set does not. I cleaned all of the connections that were easy to get to, but that did not help.

Is it possible that there is a lose wire into the radio or maybe a ground happening along one of the wires? I tried switching all the cords and even switched helmets, but that did not help. This eliminated the problem being in the headsets, mics or connecting cords.

Any good ideas on how to track this down? I am a novice at electrical connections.

Without ever seeing one,I would venture to guess that a shield ground in one of the cables at it's strain relief is breaking loose.You might be able to remove the plug assembly and shorten it's cable a inch or two and resolder the wires back.A test would be to add a external ground wire to each connection point or measure ohms to ground while moving the cable about.

Thanks for your suggestions.

I did some work last night and seemed to clear up the noise problem, but now the passenger can hear the intercom when the driver is speaking but the driver cannot hear when the passenger is speaking. All other functions of the system seem to be working good, including the radio, cb and cd player in both helmets. I swapped connections and helmets, but that made no difference.

I cleaned and tightened and reconnected any lose wires I found. I did not take the radio out, I just removed the seat and looked at those wires.

Any suggestions for this?

swapping the helmets eliminated from the plug up,so the problem is isolated from the plug to the interconnect box.And it's just one wire, possibly broken or shorted by a hair wire to the nearest terminal.I would venture to guess that if it worked before you repaired the grounding problem,the loss of the rear mic is there.

My line of thought..If I fixed one problem but created another,I'll look again at what I fixed.
Keep at it.It still sounds like broken or frayed wiring.
