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.

Does anyone know if it is possible to record from a DJ mixer onto the Yamaha CDR-HD1300 CD Player / Hard-Disk Recorder? -- i.e Can I record a live DJ set straight onto CD? And/or can I record a live set...

The recorder could not care less what the upstream audio device IS or if it's live vs prerecorded as long as the connection works and there is a signal.

Hi , My cdr 830 stopped recording at maximum fidelity, and most recently all data disappears upon finalization, the prompt reading "new disc" after recording a whole 70 plus cd. Frustrating...

I can't speak to the hardware issues that might be at play here but I would advise you to retain the 'bad' recordings. I've copied unfinalized CD's from an old DVD player. It will read the CD but you won't be able to manuever around the tracks. As I recall, the track marks will still be there.

I don't know what you mean by 'maximum fidelity'. The CDR records at the CD standard of 44.1kHz. Digital is all ones and nones. Just data. If it is written correctly or with tolerable errors the ADC of the player (ANY player) turns it all into music.

I'm not sure how to ground the system

If it's a modern unit and has just two leads running to the power plug then don't Earth it, EVER. All modern equipment is doule insulated and definitely does NOT need earthing. The only items which should be earthed is a turntable to an amplifier. The only earthing with a CD player and amp is already done via the audio leads. Whatever you do don't go digging around inside any double insulated components trying to earth them.

Car Stereo will not turn on

Most headunits (cd players) have fuses of their own. If those are are not blown, connect a simple test light to ground and with the ignition on, test your constant (yellow wire) and accessory (red wire) for power. If all fuses are good and you still have no power you can connect your red and yellow wires (whichever shows no power on the test light) directly to your vehicles fuse panel.
