The wiring came off and don't know howe they go by color it'got5 places to salder wires are r/b/or/b


If your asking about a Cobra radio then these links will have the pin-outs plus wiring color code for different mic's.
I had to guess what you was asking for as your question was kinda vague. And a Cobra 29 is a 4 pin mike, not 5 pin.
The 148 - 142 were 5 pin. I'll include it also.

Hello awchris.
Welcome to FixYa.
My name is John, and I will be assisting you with your issue today.
With your unit face-up, you will have three (3) pins in the back, the
positive (+) is the pin on the end closest to the next pin. the negative (-)
pin is the one that,s further away from the others. You can purchase this
plug at any CB shack or RADIO SHACK for a few bucks.
I hope this was helpful to you. Your Comments and Testimony,s are always
welcomed here and thanks for choosing FixYa today and in the future.

Schematics for a cobra 148 NW


Most units do NOT allow modulation adjustment as any more than 90-100% modulation causes adjacent channel signal "Splatter" therefore is subject to restrictions, hence generally that is locked. Also there really is no reason to have more than 100% modulation..as well ... why? I would suggest a voice/speech "Compressor" would be more suited.

We have a Cobra 148 nw st Sound Tracker When


It could be..
Final blown : worst case
bad mic : try another one
CB/PA switch on PA instead of CB
CB/WX swithc on WX instead of CB :you cannot transmit on weather.
Broken wire on mic jack.

Try the mic and switches first, and if that doesn't help you may need to take to tech. You can find one at a cb shop usually at truck stops.

Cobra 148nw st sound tracker - Need to test this yard sale find


go to any cb shop maybe even radio shack in your area. these plug in cords are fairly easy to find. even check with other cbers around you they may help you. these cords are usually fused so you shouldn't mess up. red fused to voltage and black to good ground. good luck

The first thing to do is to check if your power wire actually has power to it. Do this with a test light or a multimeter. Given that the wire is powered, check to make sure your ground is good. Modern cars have so much plastic in them that grounds may be hard to find. The next step is to check the rig's fuse. Make sure the microphone is plugged in, too. If none of this helps, your radio needs repair or replacement.
