I have recently purchased a new truck which came with a Maxon MCB 10 A cb radio. It doesn't matter what I do, I can't get the radio to work. There is power to the radio, but no squelch or any noise whatsoever coming from the unit. The tx goes red when I key the mike, but nothing.
Any help would be greatly appreciated!
I'm not sure about your particular model but many CB radios use the microphone push-to-talk switch to kill the speaker while the radio is transmitting. If you don't have the correct microphone or if the cord has a broken wire it can cause the radio to have no sound. Another possibility is that the speaker is bad. There is probably an external speaker jack on the back of the radio. You could try plugging a different speaker or even an earphone in the jack to see if you get sound there.

If a inline fuse in a holder the old one will aside from length have the amperage printed on it---very few mobile radios use larger than a 3 amp fuse-----look on metal ends of old fuse if have it for markings like 3ag 3 250---3AG is size, 3 is 3 amp, 250 is max working voltage (120 is fine).
12 volt 2 amp kinds or any 0.5 amps even. You want it to blow fast to save radio from damage. So, any type 0.1 amp to 1 amp or 2 even. It doesn't matter; but a fast blowing one will save radio from damage later on.
