One of my trusty vehicles, a 1982 Nissan Stanza has a strange noise coming through the speakers. It's a hum- sounds like a couple of hundred hertz, with the following symptoms; The pitch and loudness never vary (i.e. with engine RPMs). It only occurs when the lights (parking lights, low beams, or high beams) are turned on. It happens with both tape and FM. Any experiences out there with this type of noise? Thanks in advance.....SW >B-} ****SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**SW**** ** Bring that beer over here, ** Nick ** Looking under the hood... ** ** 'cause I need it to steer. ** Mason ** never did any good. ** **************************************************************************

Try varying the brightness of the dash lights and see if the noise varies. My Honda gererates noise from the dash light dimmer if it is set at anything but full brightness. I'm now used to having the panel lights set on full brightness. Bruce Carlson

I have been successful in fixing both alternator noise (which varies with RPM) and your type of noise by checking and tightening or adding the ground connections on the system. Strange how a little simple fix like that can work.... Randy

Thanks to netters who responded to my plight with the nasty hum from my car stereo. As suggested by several respondents, the problem originated from the dimmer control for the dashboard lights. In six years, I had only touched the thing once, and the radio was not on at the time. I never would have noticed it. I'm sorry I couldn't respond to all who e-mailed suggestions to me. Some of my replies bounced. Thanks again SW ******************************************************************** SW** I LOVE mankind-it's PEOPLE I can't stand!
