Hello MyPete,

You have some form of short circuit in your CB, most likley I would suspect the Power supply or the RF Power Output Amplifier. Here are some basic instruction on how to tell wher the smoke is coming from.

1) disconnect and remove your CB from your vehicle and put it on a workbench
2) remove the cover from your CB and expose the circuit board to view
3) connect your CB to an external 12 volt power source and antenna or a dummy load
4) power up the CB and determine where the smoke is coming from then turn off the power supply to the CB
5) At this point you will need a schematic of your CB (get one from www.servicemanuals.com)
6) find the point on the schematic that relates to the point where the smoke is coming from
7) using a ohmmeter determine which component and or components are shorted
8) replace the shorted and or malfunctioning components.
9) test the system (power on, transmit and receive)
10) close the unit back up
11) reinstall into vehicle
12) run tests again.


This should help

Thank you

29 ltd classic wont transmit


Hi,
Great radio when it works.
If you have your settings on CB - not PA - -be sure that your Cobra has that setting selected.
If CB -is selected and still nothing - be sure you have a working mic. These wires are fragile and can break internally. One easy way to check is to borrow a cobra mic or even drop by a CB repair shop and ask them to do a mic check with the mic - it is free.

If you have a bad mic replace it and all should be well.
If your mic is good and it still doesn't transmit you will need to replace the finals in the unit. It is common that these burn out of you got too close to someone with too powerful a radio. The CB shop will need to look at it further and repairs should not be over about 40.00.

Good luck with your Cobra.

Start with the antenna that you have hooked to it, is it grounded, is the coax in good shape, is the connector in good shape. stuff like that.

Had fixed the same problem yesterday. My cobra worked when it wanted to, when it didn't it looked like you explained. I found out that on my cobra the blue wire on the mike connector was broken. When it disconnects, no sound. after soldering, everything works fine.
