eletrical problem

[ray]

I have a 1992 525i bmw recently i have been having a problem with the electric every time i turn on the lights the sound on my raido goes out does anybody have a clue.

Does the radio switch off, or does the volume just lower to nothing?

Just had the same problem at my Renault van with a Sony radio... The ATT wire (wire to mute the radio, should be connected to carkit) was touching the wire from the lights. So when you putted the lights on, the radio tought there was a phonecall, and muted the sound..

I just started having a similar problem.... I don't have to have the lights on, but if I use ANY electrical accessory it speeds up the process. The volume starts to lower and then it seems that the sound cuts to only one side... it then completely goes silent, the deck is still lit up and I can change stations and everything. My first uneducated guess was that my alternator was going bad (I've been hearing a noise from the pulley for some time now), or the connections on my battery might be faulty (i've noticed a slight decrease in starting power recently also).
