I have an '02 Ultra Classic. Recently I can not transmit over the CB or the intercom. CB comes in but when I push the transmit it shows up I am on CB but nothing goes through. When I try to speak through intercom nothing goes through. Since I have tried both helmets with mics. in them I figure it must be something in the wiring/unit. Any idea where to start?
CB receives and radio works both through helmet ear pieces but bike does not pick up speaking through mic. I think I checked all fuses and they seem OK. Any help would be appreciated. Thanks.

 

theres an adjustment for sensitivity on the mic, in the radio setting.
