Cobra 75 Bad Ground?

When I use the left turn signal, or hit the brakes my cb clicks along with it. Seems like the installer messed it up? If I turn up the squelch, it gets somewhat quieter with the brakes, but still pops once every time I hit the brakes. wtf?

What did the installer connect it to for power and ground? Most "installers" don't really know what they're doing... they can get it working but they don't know enough to get it working well because they don't know the basics which are especially important for 2-way radios like CBs and ham radios. Hence your problems with clicks and noises.

The first thing I'd do is verify its power connection. It should be getting its power from the battery or very close to it... not some random wire, fuse, or cigarette lighter. Same with the ground. A weasly ground connection is as bad as a weasly power connection.

The best place to get the +12 volts for the CB is at the battery or very close to it. What model and year Jeep do you have? That info will help for suggestions on where to get your power from.

Powering 2-way radios directly from or very close to the battery is the way to go since the battery is the cleanest most noise-free source of power on the Jeep. Random power connections like those under the dash can be full of noise like alternator whine, pops, clicks, etc.

When you have a choice, buy American.

Thanks Jerry, I'll make sure it's connected to the battery on your advice.

Also make sure the ground is connected. Not just a ground through the mounting bracket, run that negative wire back to the battery as well.
Just because you're offended, doesn't mean you're right.
