radio issues

originally had no radio when I got it, just bought a cd player/radio and harnesses..installed no prob. Its not getting power though. Im wondering what to do next. I reckon Ill get a volt meter to check the AC wire. Other than that Im at a loss as what to do. Any thoughts on troubleshooting this?

Yup, verify you have voltages where you need them and go from there.

and by AC Im assuming you mean accessory and not actually looking for AC voltage.

It's possible that the fuse that protects the power circuit has blown while you were connecting the harness

even on the accessory wire?

There is typically two power connections on radios, One for constant 12v, the other for switched power. If one or the other isnt there sometimes the radio wont come on.

You just beat me to it. I don't think there are standard colours, but take a look at the red (power) and the orange (memory). They are generally accepted colours in England.

I'm a dummy with electronics... so I need it practically drawn out. the red and yellow are my power source? I hooked the volt meter red lead to the red and black to the yellow and get 12+. all other wires are for speakers and are correctly hooked up to corresponding color. ground is set. this jeep originally had no radio so I'm at a loss getting one installed

If it is a modern unit, it will probably have a memory circuit which stores your radio pre-tunes and the CD position when you power the radio down. This needs to have a permanent 12V+ (I believe you call it the hot wire in the US) or the radio will not work.

Do you have a wiring diagram for the radio?

If not do you have a make and model. You should be able to find a diagram on the internet.

I'm not familiar with the wiring on a YJ.
