Any cb gurus reading this? Wired in my cb to an ignition power source running to my radio, as soon as it gets power it turns on, runs through its start sequence and immediately shuts off. I can unplug it and replug it in and it does the exact same thing. Only lights up when it first gets power then shuts off. So then I tapped it in to a constant power source and it does the same thing. Will only start up, run through sequence and then shut off while it still has power running to it. Both wires I tapped into were going to the radio. One with constant power and the other with power when the ignition gets it. Ground was tested and is good as well.
