Driver headset intercom quits transmitting occasionally. I hear music, CB, my passengers voice but I don't have transmit. Everything will be working properly an then suddenly it quits. I tried swapping out the lower cord with wifes but same issue. I haven't had an opportunity to swap helmets with a known working one. It's raining today so I thought maybe someone might have had this issue and point me to a connection/connector on the bike to look for corrosion etc. Thanks.
