On my 96 250 I was driving the other day and notice that when I came to a stop the volt meter on the dash would dropand lights get dim..As I would go give it gas to take off it would raise up and lights get brighter.The battery light came on once but went out soon after.I am thinking maybe the alternator is going south but just want to check in here before I go and replace it.
Sounds like you may have it right. You can take it to any number of auto parts stores and they will test it for you if you wish.

'95 F250 ext cab long bed, PSD, 5 speed, 2 wheel drive, 3.55 gears, 286,000 miles, Edge Evolution CTS (LINK TO MY REVIEW), LUK clutch, homemade REAR BUMPER, open element AIR FILTER, 36" ARE contractor cap. With tools, full of fuel and me on board (300 lbs) steer 3620, drive 3860 total 7480.
I have the same ongoing issue, except, my problems included a slow spinning starter. I replaced the batts w/ the ones in my sig. I thought the batts were the problem for sure. It spins up like crazy now, but I still have the dimming headlights when the truck returns to idle, raise the rpm's and the lights brighten as normal. The alt still charges, according to the dvm, so Ill eventually get around to pulling the alt off and have it tested. Can you just buy and install the reg, or is it internal?

[/ QUOTE ]From what I see it looks like the reg comes come the back of the alt with a few torx screws.I here that Napa carries the reg separate.
i had the same problem. what happened to mine is one of the brushes broke. i would drive like normal it would be fine. stop volts would drop. took it apart and one of the brushes broke off. replaced them and it worked better than ever. orily sells the brushes. (think i mis spelled)

when you replace the reg and brush assm--look closely at the slip rings inside the alt--its what the brushes ride on--they get much of a groove in them--and new brushes wont last long---
