My damn alternator went out yesterday. I was on my way to work when my charging light came on. On the way home last night I could watch my volt meter just drop. Had to take a vacation day so I can change the thing. But first I must charge my battery up so I can get to the parts store and pay the piper for a rebuilt. For anyone who thinks its my battery its not, its only about 4 months old and when I pulled the nagative cable the truck died ( old trick my dad taught me). So unless I have a loose wire on the alternator it is bad. What is really ironic is that the company I work at builds alternators and starters. If only we made them for F150's!
