    Hope someone might be able to offer some advice.

    I have a tomtom Ipaq cradle with wired GPS receiver that is powered from the
    cigarette lighter. The plug that goes into the lighter socket in the car has
    disintegrated. I have a separate HP car charger for the Ipaq (5V 2A) that I
    don't use and thought I could just chop the jack off the power lead for the
    cradle and attach it to the Ipaq lead. However, having chopped both jacks
    off and come to join them the Ipaq lead has 3 wires (red, yellow and white)
    and the cradle lead has just black and white. I thought I might just be able
    to measure the resistance of each wire to determine which part of the plug
    each is connected to but they all show reduced resistance. Is it possible to
    do what I am attempting and if so how!

    Thanks

    JRS:
    More than likely the "disintegrated plug" had some electronics in it to
    reduce and regulate voltage. I wouldn't screw around with home made
    remedies..... get a "factory" replacement plug and cord and save yourself
    some greif.

    No electronics in it. Just wired dirctly to the contacts but maybe thats a
    clue as to the voltage to the cradle - 12v?

    Maybe I shouldn't use the 5V cable

    Go to the dealer for your car, and get the necessary parts to fix it.
