2004 renault scenic cd player

Sounds like your 12volt permanent to the radio is down check the fuse and connection to the radio if there is no permanent to the radio it will lose the memory every time you turn the car off. If it is a new installation check that the permanent and ignition wire are going to there respective wires on the unit.

Red - Power - Connect to Acc on ignition or battery positive. Connected to Battery the unit will not power down when the ignition is switched off
Yellow - Memory back-up. Connect to battery positive
Black - Connect to vehicle earth or battery negative
Blue/white - Used to power up remote power amplifier or power antenna. Do not draw more than 300mA at 12V from this line
White + White/black - Front left channel
Grey + Grey/Black - Front right channel
Green + Green/black - Rear left channel
Violet + Violet/Black - Rear right channel
Use the wire with the black line in it for negative on any channel.
Do not earth any speaker wires.
RCA output jacks are used to send the output from the unit to an amplifier if you have one and cannot be used to power a speaker.

Im not sure about power wire red black ground and yellow not sure?

Connect black to earth or battery negative.
Connect red to battery positive or the acc lead from your ignition switch. If connected to acc the unit will power down when the vehicle is switched off. If connected to battery positive it will remain on irrespective of ignition switch position.
Connect yellow to battery positive for memory power. The moment this lead loses power all the settings/memory on the unit will be lost.

I have just replaced the cassette player in my W reg ford fiesta 1.25 Z-tec with my alpine CD player. I have all the correct wiring but the CD player doesnt even switch on. I'm not sure what I need to do...

Check the fuse in the back of it, check the fuses in your car, check that both the power leads are connected to the correct power source as there are two, switched and permanent 12v power from your car, check the earth wire is connected securely to a good grounded source that goes to your chassis, If the face of the stereo is removable make sure the connections on it's back are clean and free of fluff/dirt etc and properly in place, Check that the wiring harness is properly clipped into the back of the stereo, double check all your wiring connections, check your car battery has power. Sorry just had to throw in that last one 8P
If i've helped you please help my rating. a vote would be appreciated also 8)

There are two battery supplies to your radio.

The main one via the Ignition Switch

The permanent one to feed + retain the this one is missing

Check the wiring, connectors + fuse

Re-wire stereo in rover 400 cant find power wire

The following should be right, unless your car has different wiring colours, there are a few variants...

Yellow and Red = Switched +'ve feed from the ignition
White and Blue = Permanent +'ve feed
Black = Earth (-'ve)
Red and Black = is for the illumination when sidelights are switched on

If the above doesn't work join the following MG-Rover forum: And add me as the referer: HotTubRepairer

Bought a car with a panasonic fx220n cd player fitted. The cd player keeps playing after the ignition is turned of, is it wired up incorectly

yup. There are two power inputs, one unswitched so the deck can remember presets, and one switched so it will turn off when you turn off the ignition.

Either someone hooked both power inputs to 12v+ unswitched, or they've hooked the two up backwards.

There should be a red and a yellow wire on the unit. Typically Red is the switched power input, and yellow is unswitched.

Wiring of a Panasonic CQ-C1001N Car CD Player into a Morris 1000

You can get wiring diagrams on line, do a search using the players full name. Is your morris positive on negative earth? you will have to swap it if it is positive as the player is negative earth only (usually dynamo is +ve and alternators are-ve ) I have changed lots over when dynamos were common, turn the battery round and pull the 2 wires off the dynamo take a wire from the +ve battery terminal  and "wipe it across the 2 terminals on the dynamo, this will make it -ve earth too, re connect the dynamo and off you go

I didn't actually get what you mean by "earth disappears" If you mean that you are not able to power the cd player from the car, check the voltages on the wires with a meter and with a 12v bulb or such a load to confirm that voltage is actually coming. The live should show +12 volts permanently and the switch+live should show the same voltage when the ignition is switched on. If it doesn't show voltages, check the fuses and also earth wire connection. Good luck.

No remote on VDO CD 139 CD player

If the head unit does not have a 12v switched output you could connect it to the cars ignition which means that the amp will switch on when you turn the ignition on and it won't drain the power when you switch off
