Hi Len,

First off I am sorry and I will fall on my sword. I am only human and need a reminder every now and again.

I will respond via PM.

Hello Fellow Campers,

I have a 2010 FR Shockwave T29SALX Toyhauler. When I have the outside flood lights on (has a sliding switch for brightness), I get a buzzing noise over the inside and outside stereo speakers. The buzzing is quite annoying when listening to music, or watching movies. When the lights are turned off, the buzzing goes away.
Please advise where I should start troubleshooting. Is a loose ground? Should I check the ground wires to the lights, or the stereo, or the main chassis? Any help or advise is GREATLY appreciated.

gunner bob, a few points.

first, this thread is 3 years old.
second, unfortunately Bob Fields no longer works at Concertone and apparently no one there is willing to fill in for him.
third, posting which model Concertone you have, would help or at least a pic of it.

Also, what kind of lights are the floodlights. If they are LED, then the slider switch is a PWM dimmer, which generate a lot of noise.
