electrical problems
I have a 1999 f-250 super duty w? 215k, i just replaced all at the same time, starter, altinator, battery, batter connectors. i am now gettig the batter light indicator flash on and the truck now pulsates and the voltage jumpes all the way up to 18v and then back down on a constant mannor. i had a test electrical test done at my local mechanic and it came back as normal. as it is running, interior and exterior lights fading in and out. any idea where to check next. i am a little stumped

If it didn't do it before then it sounds like you got a wire crossed or left something loose. I recommend going back through it. You can also use the electrical forum for direction: https://www.ford-trucks.com/forums/forum62/ See what the experts there recommend.
