My intercom does not work. My system works on other wings. I did a continuty check from the radio harness back to both helmet plug ins and there are no disconnects. That tells me that it is something in the radio. Does anybody know who works on these. I don't want to spend 2000$ on a new one. I didnot by a sysyem until after the warrenty was up, so I am on my own.
