Crackling noise on radio
Hi
I have a Kenwood head unit which is less than a year old in my MG. The unit works perfectly well except sometimes I get interference on the radio when I use my wipers, window washer, and electric windows. This only happens when listening to the radio, as the CD player is not affected at all. This problem has only come about in the last 4-5 weeks. Where should I look - check the earth, or take the radio out and check the connections etc. Any pointers will be appreciated. Thanks |

Your power for those mechanisms probably runs close to the antenna wire for
your radio. There's probably a decent bit of current running through the wires to your wiper motors and power windows. If it only recently started happening, maybe a wire from the antenna is beginning to chafe or something. I dunno... sounds like EMI to me. -- - AUSTIN BECKER wrote in message oups.com...

This is a TOTAL shot in the dark, but a few years ago I had similar problems
JUST BEFORE my alternator gave out. You may want to check your voltage with a multimeter and make sure you are getting a healthy 13.5-14.4 volts. Just a thought. MOSFET wrote in message oups.com...

Crackling noise on radio
My guess is EFI.. I've got an old 69' Chevelle and found out that my spark
plug wires were causing problems with my reception. They were the original wires with no supression. they never built those old cars with too much thought about head units in mind. Could be an alternator like MOSFET said.. I actually think it's the wiper motor causing the problem, not the wiring. Motors like wiper motors can generate interferance as well.. if it's not shielded properly it can cause problems like the reception to your radio.. There's really not much you can do about shielding the motor unfortunatly.. wrap a lead cover around it? lol.. I bet if you relocated your antenna as far away from your wiper motor you might be ok, without changing a thing but the location. it's iffy though. Mike wrote in message oups.com... Thanks guys.
