I recently had to buy a new radio for my car because the old one broke. However since I put it in, whenever I've tried to use the radio function (as opposed to the CD function) I get the noise of the alternator kicking back through the radio. This didn't happen with the old one, but apparently it's because the newer radios tend to be more sensitive. Anyway, the guy at the shop said the alternator could be working too hard, now I knew my battery was going so I changed it, and had an alternator test and now that's all good. I've also been told it could be bad earth cables, which I'm yet to test and clean, but while I'm on the subject could it really be those?
Leaving aside the earths, what could this problem be? If it's a simple case of buying some sort of suppressor then where can I get one from and how and where do I fit it?
I have a 2000 reg Ford Fiesta 1.3 and the radio is a JVC KD-G441.
