Hooked wires up backwards

Did you check the fuse, and the circuit breaker to the cig. lighter

 

someone i know did the exact same thing with his radio. replaced the fuse and made sure the wires were the right way.

 

Don't forget to check the fuse in the Cig Plug too, you could have blown the fuse in the truck or in the plug, or possibly both.

 

Smoke come out, it's fried. Things like diodes, chips and transistors can't handle backwards current.

You can always let a CB shop look at it. Diagnostics might be free.

Plan B, buy an identical one and return that one. I didn't say that.

 

OP said smoke came out of another one, this one just isn't working since he plugged it in.

 

I did that once........ Turns out the wire with the "ribs" on it was the ground and the "smooth" wire was the power....... Luckily it was only on a cheap little 20 dollar uniden radio......

 

It be just the fuse. But if not look for a burnt diode. Just follow in from the power cord. And you should see it. A Black and crispy part. Should be a very easy & cheap fix.

 

You sound like the fellar that cut his pants twice and they was still too short...
