Default Volts meter spikes....help...

Hello, I have a 94 ranger 3.0 5speed ranger, and im haveing issues with my volts meter, to start off, the volts meter is fine when i start driving but when i get about ten miles down the road the volts meter starts spiking from about 14.5 volts to like 17-18 volts, it doesnt stay there it just twitchs from 14 -17, i have load tested the batter with and with out it runnig, it holds and 12v when not running, but it will twitch on the load tester also when i have it running, ive replaced the alternator, battery tested good, and have replaced the battery terminals, sometimes with the ignition on the accesory position, my lights will dime out and cut the radio out and come back on...im at a cross road and dont know whats goin on, also when driving it at night when the gauge twitchs the lights will flicker from bright to realy bright like police lights, it doesnt change when i hit bumps or nothing, its gotta be somthin electrical but dont know where, any advice will be helpful, thanx

You said "but it will twitch on the load tester".....I would check all your connections again and then try a new battery.

I think you have a bad connection somewhere such as: a body ground; engine to body ground; or even a faulty battery (shorting out internally). I was going to say the alternator because a bad regulator (probably integral in yours) would cause a voltage flucuation like you described. Try new battery......good luck...let me know what you find out.....

I would say the regulator. It's the only thing that would make your voltage too high.

Well come to find out today the truck wouldnt crank,i put my load tester once again on battery annd hit the load button on it and it peged to 0volts, pull off terminal and it was had corrosion like it did once before when i replaced them, this time i put some lube grease on the positive wires to prevent the corrosion from coming back, so to say the problem is solved and no more gauge twiching, it rest a little above halve volts and stays steady and cranks right up no more loose connections, thanx everyone for the help...

Sweeeet!!!!......guess the ole saying "check the easiest things first"......is still good advice. Sometimes we all get to "over" analyzing things.......such as when I had a check engine lite problem and it turned out to be a cracked PCV hose.....HAH!
