    I need to test a headunit that I took out of my previous car before I sell it on eBay. I seem to remember that the matrix display was a bit faulty so I need to make sure its ok before I sell it.

    I want to just hook it up to the car battery with a few wires to get power to it so I can see if the display works. I don't need to hear it.

    What do I need to connect to what to get it working? Is there anyting I need to do to fool it into thinking the ignition is on?

    Its a kenwood minidisc headunit by the way.

    cheers

    I tested one recently using the car power source but you have to ensure the stereo is earthed as well (usually from the car too)

    I presume direct from battery would be ok but it must still be earthed.

    Can you earth it on a bit of exposed metal in the engine bay or does it have to be earthed to somewhere special.

    How exactly did you go about testing yours?

    I wouldn't recommend that. The average car battery charger gives out far more than 12 volts off load. Also, it is unsmoothed, which will make most radios buzz rather loudly.
