    Flickering Odometer and MID Display?

    Noticed this for a while but never posted it.....What would cause the odometer and MID display to occasionally flicker rapidly at while engine runs at idle? A cheap voltmeter plugged into the cigarette lighter reads a steady 13.9v. Resistor plugs??

    One of two things I reckon:

    Either the thumbwheel control is failing or you have a diode failure in the alternator - a meter is damped so it will not show fast deviations. You could set the meter on AC and see if you get a reading, that would find it....
