Philips fm92 cb radio

I have just purchased this radio and it has two red wires for power. One red wire has a black marking but both wires have fuse holders on them. I am assuming the red with the black marking is negative and the straight red wire is Positive when connecting in a car. What is throwing me is that they both have inline fuse holders on them. Also the main unit has a metal mounting frame which may be the earth. Can you please tell me if I have the wiring correct with what I have said above. Thanks.

I don't know how I copied and pasted so much sorry about that. But my question is I have orange and red wires with fuses and black wire without do I hook both red and orange to hot and black to ground?

it depends on what radio if you have a cobra 18wx style or maxon's, or a radioshack type the red is constant power 12v, orange is a switched 12v.. IE key like a stereo, and black is ground. if you have a 25 or 29 ltd types or exports they only have 2 wires red 12v and black ground. but you do find some power cords that have all three, and the orange on the 25 / exports are not used.

I just got my first cb and am trying to install it. I have connected the red wire in the fuse box( to the radio) and grounded the black wire. turned the car on and I cannot get any power to the CB, but the...

Take a deep breath and start over! The best way to power this little radio is probably through the cigarette lighter or 12vdc accessory jack. It is simple and straight forward and no fuse box or negative ground wires to worry about. Go the Radio Shack, purchase an adaptor (cig lighter type) and hook it up to your radio wiring being careful to watch polarity. You may have to have your ignition on to run the radio, but that is much safer that maybe blowing up the unit.

Unless you are running a larger more powerful unit or an amp, there is no added benefit to hooking the radio into the fuse box.

No power to cb

first thing is to make sure the power leads to your CB are hooked up. The black wire from the back of your CB need to go directly to the car battery "minus" "-" or to a metal screw which is actually touching metal not plastic. The red wire needs to go through a fuse. Sometimes there are inline fuses, that is to say built into the red wire that you can remove and check. If not the the red wire should go to a wire that is coming from your cars electrical fuse box. Using a multimeter to check voltages, set it to read DC and to be able to read at least 20 volts. attach the black lead of your meter to the same screw or point where the black wire from your CB is at. Next if your red CB wire has an inline fuse remove it. we will test it in a minute. Now where you have removed the fuse, with the fuse out touch the red lead of your meter to the red wire of your CB but the half that goes the opposite direction of your CB. Is there 12 volts there? oops turn on your ignition and test again. you should have 12 volt reading on your meter, or close to that. If so that means you have power up to the fuse. Turn your ignition switch back off. Now set the meter to read ohms or if you have a buzzer symbol, set it to that. Now touch the red and black leads of your meter together, note what happens. something should happen, meter goes to almost zero and probably makes a tone, if you have it set for buzzer. Now touch the leads to the fuse while it is laying on a table. One lead to one side the other lead to the other side. Doesn't matter which lead goes where. You should see or hear the same thing you just did a second ago. If so then the fuse is good. Put it back in the red wire where it belongs. make sure both ends are snug when you fit it in and tighten up.Try your radio again with the ignition on. does it work? It should if what I said checks out. If not then you will need someone to look at your radio internally for a bad solder joint where the red wire comes in or even a bad switch. If you have made the check I suggest and you don't see anything on the meter when you check for voltage. set the meter for DC voltage, touch the leads up to your car battery just to see if the setting is right on your meter and it does work. If it does then continue on. You will need to do this: touch the red wire of your meter to your cars battery "+". You might need a longer wire to attach to the red lead to be able to reach the battery, because I want you to touch the black lead to the black CB wire at the point where it hooks to your car. Do you see 12 volts now? If not the black wire connection where it makes contact with the screw is not really grounded. Find another ground and try it again until it works. If that all checks out and the radio still doesn't work we are in trouble. The basis of this is that the red wire has to end up making a connection to the car battery "+" one way or another and the black lead of your radio needs to go to the car Battery "-". If your red wire has an inline fuse you could just run the wire directly to your battery "+" and the black wire to your battery "-" It will work if the fuse is good and your radio works. If not then your radio needs help. The drawback of running the wires like that are , would be the radio would not go off and on with the ignition switch. woopie!

I purchased a used Cobra 19 DXIV cb radio that has a black & red wire with a fuse. I was told that the wires can be wired into the fuse box under my dash. How do I do this?

You may need a test light to do this.

1. Decide if you want the power to the radio to be full time or only when the key is on.

2. If you want part time the easiest power source to access is the cigarette lighter. You can either splice into the power wire going to the cigarette lighter (center lead) or you can get a cigarette lighter plug and install it on the end of your two power wires. Center is the positive. The plug costs about $4 and takes about 10 minutes to install.

3. If you want full time you will need to find a circuit that is hot at all times and splice into it.

Use a noise filter on the power as just about all circuits in the vehicle are liable to be noisy power circuits and this will show up in form of excessive static noise during radio operation.

The red with the fuse is your positive lead. Do not hook these up backwards as this will certainly ruin the radio.

Where do the 3 wires in back of my Cobra18wxst11 go? Can I use a cigarette lighter plug?


"Where do I connect the three power wires? (radios with 3 power leads)
Answer: Connect the black wire to chassis ground.

Connect the red wire to a switched +12 volt source, such as the fuse for the AM/FM radio.

The orange wire is for the memory retention of your CB radio, and should be connected to a constant +12 volt source. The fuse for the brake lights is usually a good choice.

With the radio wired as above, the radio will turn off when the ignition is turned off. The orange wire will provide power to the radio so that it remembers the channel.

If you are installing your Cobra CB radio in an application where you wish to utilize a cigarette plug to power the unit, connect the black wire to the negative lead (side terminal) on the plug. Connect both the red and orange wires together to the positive lead (center tip) of the plug. Your unit will function properly this way but will not retain the channel memory. When power is applied your radio will come up on channel 9."

Connecting a Cobra 29LTD to a Pyramid PS-3KX 13.8VDC Power Supply

The wires should just attach to the red and black terminals on the radio, strip some wire unscrew the terminals a little wrap behind, and tighten again. Good luck! Or buy some banana plugs and they will plug right in the front
