Cb radio

There are not many wires to mess up. Did you overlook something

 

TMI...

 

NEI

 

A frequent item that gets missed is not putting the frangabulator shaft in front of the re-dibulation transfer switch. Then, if there's not enough glorp on the stem of the bobblefrump, you'll get sparks across the gap of the recondabell. Did you get a left-handed antenna (if on the driver's side) or a right?

 

When I had a similar issue, swapping out the luminode on the tarbanator is what sorted it out

 

Check the in-line fuse. Pretty easy to blow one if you accidentally touched the wires backwards. If it is blown, most truck stops carry them.

 

What Thrasher said. Not all trucks conform to the usual "red=hot, black=ground" convention. If your inline fuse blew immediately upon firing it up, the "reverse-biased" diode protects the radio by blowing upon seeing the leads reversed. Unfortunately, an all too common "fix" is to keep replacing the fuse with larger and larger current ratings, until finally the radio fries to "protect the fuse."
It's easy enough to check the polarity of your power wires with a digital voltmeter, around $9 at Harbor Freight. And a 2- or 3-amp fuse is easy and cheap enough to keep a couple in stock in your cab for the occasional fuse blown by a power surge.
