How to fix my connex 3300 it has no power

This is a problem that can't be diagnosed over a computer. There could be several reasons that the AM regulator is being blown. The radio needs to be serviced by a Radio Technician.

There is something shorted in the power supply. See if you can get a schematic from their website. Most likely parts to check are the voltage regulators, protection diodes and capacitors. A shorted diode will go to ground too.

sounds like a power amplifier failure. have the rig serviced

4600 turbo? 3300hp? never heard of a 3300 turbo

There is a board in the CB called a PCB board. If you open your radio it is a little circuit board. Held onto the side of the radio by a screw and has two or three connectors leading to the board. Replace that little board and your radio will be good as new. I have seen radios come in my shop many times and this is the fix. What that board does is send a signal to the crystals to start mixing a frequency. When it goes out it just sticks where it is at. Here is a link to a place that can take care of you. http://www.hyelectronics.com/default.asp You tell them you need the little PCB board for a Connex 3300 inside the radio. Might be $35 or so.

The center wire doesn't do anything. Its the outer wires. You can get a standard CB plug with 2 wires that will work just fine. If that plug fits, I it will work. My concern would be if the pos and neg are the correct sides. It should be, But I wouldn't know unless I looked at it.

DO NOT HOOK the radio up with the power wires backwards. Or you will blow the polarity protection diodes. They are there to blow if the radio is hooked up backwards.

If you look at the plug. There is a side the goes to a point, and the other side is square. The black wire, Ground, should be on the side that goes to a point. If it does, then that plug is standard.

It's fine to use and hook up in the usual way. Do not hook up the center wire. It does nothing in the radio. You can clip it, and put a bit of shrink tube on the end as so it does not have a chance to short on anything.

If you are not sure about hooking this power cord to your connex, just go on ebay, and get a regualr CB power wire. They are cheap. It should only have 2 wires.

The best way to set it is to get you a radio check, go to channel 19 and ask someone about three to five miles away to give you a radio check, start with your modulation all the way open and go from there.....hope this was helpful...

Check your Antenna connections, Check Final Power Transistors.

Either the power cord is bad or the connections to the power jack inside the radio are disconnected or broken. Easiest thing is to try a new power cord, if it doesn't help have a radio tech check out the unit. This should be a very inexpensive repair, usually under $20.
