Autocom crackle
 

Hi, I've just got a sprint st, it already had an autocom fitted, just got 2 new headsets and gone to test the kit. However there is a bad crackle when the riders helmet is connected. The wire is routed to come up by the seat and tank. I'm worried that I wire inside is broken, any ideas or advice, can a new rider lead be fitted to the unit itself???

What autocom unit is it? They have various models.
