    Bad alternator?

    I got this what seems to be like power surging problem.

    At idle the lights at night are alright, they will get brighter as I go higher in the rpms, and while crusing at like 85 at about 3500 rpms, they seems to flicker ever so lsightly.

    Also the inspection lights (brake lining abs ect..) will get really bright and light up while going through out the rpm range the higher I go the brighter.

    My radio seems to be relaying the increased amps through the speakers also, its a whining noise that gets very loud as the rpms increase.

    It was funny too, when I put cruise control on it seemed that it stopped at least the dash lights getting brighter.

    Any suggestions?

      Good Idea, Maybe use some electrical contact spray too.
