447 will not take power from power suply

  • If you have an inline fuse make sure to check and replace it if needed. If the radio was hooked up backwards then you need to go to radio shack and pick up a replacement diode. 1N4001 will be the diode you need. It allows current to travel one way but not the other. When you hooked the radio up backward it blew, like a fuse. Here is the diode at Radio Shack.

  • When you pull the bottom cover off you will see this diode in the board right by the power cord connector for the radio. Most of the time they will be chipped or even split after blowing from reverse polarity. Pay attention to the little "arrow" on the diode because there is a negative and a passive to diode. Anode and Cathode as it were. The Anode flows to the Cathode. The "tip" of the arrow is the negative side.

  • Look with a flashlight to insure you did not blow a tracer too.

  • Hope this helps.

Im a trucker so when i plug my power wire the fuse blow why

You probably plug it in backwards at some point. When you do that you blow the polarity protection diodes. They are so you do not blow the radio.

Get a N14003 diode from radio shack.

Open the radio's bottom cover where the speaker is. Watch the speaker wires.

Near the back right of the board where the power cord plugs in left of the transformer, look for D23. Its the same diode as the one you bought from radio shack. It is most likely burnt.

Remove that one and replace with a new one.

The radio should work fine now. Be careful when plugging that thing in.

Radio shack cb radio 21-1703

OK. I do not know the exact number for the diode off hand, because I don't have the same radio in front of me. On most cb radios, this diode is usually located on the component side of the pc board, close to where the positive lead solders to the board. Most of the time when it burns, it just becomes brittle.

If you do replace it on your own. The diode is called a rectifier diode, which you can pick up at radio shack or at The part number is between 1N4001 to 1N4008. When installing be sure to observe polarity, making sure that the side with the silver band is facing the direction of the arrow.

If I can help anymore, please don't hesitate to ask.

Sony rear projection tv How to de-solder

I would suggest not to desolder that transformer until you are certain that is defective.
Try to change D6116 and D6301 first.
You can try Radio Shack or check this site.
Good Luck.
