Charging Light Flickering
Hope some one can Help. On my 250 super duty the light on the dash keeps flickering, so I replaced the alternator thinking that the voltage regulator was going bad. That did not work can some one please give me some direction on what to look at next.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>

Are you talking about the red battery light on the dash? Mine was going off and had the alternator tested and it was bad. Put a brand spankin new one on from Auto Zone (gold series or whatever...the one that is all brand new and not reman)
The battery light was still flashing after a couple of days....took the alternator back and had them test it and the new one was bad. All they had was the reman so I got the difference back.
Take the truck to auto zone and have them do a test, its free. These alternators have to pull 12 volts or otherwise that light will come on.

Mine just did that saturday night. I have an "oh-rye-lees" alternator in it and I just figured I was going to need another so I ordered a motorcraft. Funny thing though, when I checked output it was at 14.5v and I have not been able to make the light flicker again.
This all happened after jumping a friends car. I gues the alt couldnt handle 3 bats.

Any auto electric or battery shop should be able to determine if you have a bad battery, alternator or this type of wiring problem at little or no cost, the cost is locating the problem wire.

Just an update on mine, my battery light had not flickered in over a week. The other night it started flickering again and the lights would dim pretty low every time it would do it. I put the new alternator in the next morning and it has worked like a champ. Funny how the one I took out still tested good on the bench. I think it was flaking out after it would heat up.

I am having the same problem with a 2001 F-350 V-10. All the lights flicker while the truck is running - dash, dome, clearance, head, tail, etc... Even the voltage gauge on the dash bounces to the same beat. Almost like there is a pulse in the lighting circuit. It's very consistent...not like a short or bad conection.
The truck has a new alternator and Battery. Both have been swapped for testing purposes and nothing changed. Although when you unhook the battery while the trucks running, the flickering stops. This is very interesting....but only puzzled me more, because 2 alternators tested good....but didn't fix it!
I'm wondering if I should try an alternator from a different company?
Is the Ford (motorcraft) one recommended??
Or is it the just the difference between New and Reman that is important?
Also, does anyone know what the minimum voltage is needed for this truck to function properly?
