Crossed power wires on uniden c b radio

Hi
To wire your PA speaker, use the orange (+) and black (-) wires. This is from the owners manual, page 5 from the link below.

If it is new take it back and have it checked

Sounds like you have a short in the wires to the mic jack, or in the mic cord.

Sounds like you have either a short in your speaker wire somewhere, wires touching in the back of the unit or a short inside the stereo itself... Try pulling the radio out and unhooking all of your speakers...Turn unit back on after all speakers are disconected...If unit still shows protect, then radio is bad...If it doesnt, power off and hook up speakers one by one and power it back on till it shows protect again....When it does, the last speaker wire you hooked up has either a crossed wire or the speaker is bad...

Hello,

have you been using the uniden pc68ltw cb radio without the fuse blowing before?

If the uniden pc68ltw cb radio has not been blowing fuse before, then might be a problem from the radio. This problem should be a power related problem.

The fuse blowing means there is excess of current. So while your trying to refuse, thicken the wire.

Best regards.

careful not to cross the speaker wires you will blow the channels. check wiring diagram and ground wires
on the body from the radio. You may have the LED power hooked up but not the main power for the radio,
hope this helps

The radio was probably wired backwards at some point. There is a reverse polarity diode inside that must be replaced to fix this. If you have continued replacing fuses and plugging it back in, there may be further damage such as finals or audio amplifier chip as well. you will need to take the radio to a qualified repairman for service. If it is simply the reverse polarity diode, your bill should not be more than an hour's labor charge.

Hopefully this is the first time this happened to this radio.Take off the cover's(top & bottom)and where the power wire's come into the back of the radio if you look on the component side you should see a diode that is generally larger than the rest of the diode's as well as maybe a different color(i.e.black with a silver band as opposed to clear with a red band)this is your protective diode what you do is replace that diode making sure you solder it in with the band on the same side as the one you took out,You can also just cut one leg so it's not making contact BUT when you do this you have no protection so if you ever cross wires again the radio is history so my main advise is replace it don't just cut it.Good Luck and have a good day.

I cross the wires on my radio hooking it up now I have no power .

the reddish-orange one and the brown one. The green and yellow ones are for data coming in.
