Most cb radios have protection diodes that are made to burn out to save the radio in this situation. Usually you can replace them with a rectier diode between 1n4004 and 1n4008. They can be purchased at Radio Shack, or if you need more stuff, you can get them from Parts Express. This unit is the same as a cobra 29. If the pc board layout and numbering is the same, then the protection diode number is D23, which is located in front of the pa speaker jack on the main pcb. If you need more help, feel free to email me at firstname.lastname@example.org.

Hello bubba, the wiring code for the radio is
Galaxy DC-521S (4 wire)
If this is the power /echo mic like it looks to be from the Workman catalog, then I can't remember what the wiring code is for the mic. I do know, that the audio wire has the ground/shield wire wrapped around it.Could be just about any color. Put the shield on pin 1 and the audio wire on pin 2 and all you have left should be 2 more. If you get it backwards, then the radio will key up as soon as you turn it on. You'll have to key it to hear the speaker. Just reverse the 2 on pins 3-4. Hope this helps as it's been over a year since I've seen one. Let me know,,, Mechanic
