    Check your alternator output with a voltmeter. PROBABLY indicates that the voltage regulator is starting to go. Should be visible in the trucks volt gage as well.

    yup i agree, a flicker would be more of a rappid cutting out and on

    as you idle you moters rps change a bit and the regulator is supost to compinsat for this, if your's is not watch out, this can also make too much power witch can kill stuff.

    if you have a hanes or chiltons, it should show how to chech the regulator by by passing it and checking the volts
