Have you set it up properly ? Consult instruction book. If you are certain it is defective, get a refund under the warranty (if it's new it should still be under guarantee)

Connecting a Cobra 29LTD to a Pyramid PS-3KX 13.8VDC Power Supply


The wires should just attach to the red and black terminals on the radio, strip some wire unscrew the terminals a little wrap behind, and tighten again. Good luck! Or buy some banana plugs and they will plug right in the front

PS36K power supply overload problem


Most of Pyramid's supplies are based on the LM723 voltage regulator. The DATASHEET should tell you most of what you'll need to know to repair it. THIS is the schematic diagram.

If the output voltage drives the voltmeter to the end of the scale, it likely has one or more shorted power transistors.
