Alternator Quit
After 166k the Alt. finally had enough. Surprisingly no Gen/batt light on. The only indication was the Abs light was on when I started it yesterday. I was going to scan it when I got home but it wouldn't start after work. New Motorcraft alt. and maybe 2 new batteries we will see how they test out.

Had mine go out at 135k miles on my 01.
Dropped new alt and 2 batteries too...
Nothing worse then trying to find someone without a big truck who's willing to give an Ex a jump start... Thankfully in Texas this isn't often an issue

Just replaced mine at 128k. I can't get the ABS light to turn off. I've followed the procedure to clear the keep alive memory but it still won't turn off. I'm sure it is because of the bad alternator. Is this something that I am going to have to take it to a dealer to have done?

I had same issue with mine...unhook both batteries to kill power, flip the headlight switch on to drain any residual power in the system. Give it 5 min, reconnect and go, should be no problems from there.

Same here when mine went......no warning light at all.......and the guage is about useless too.....no numbers
Lucky for me a guy in an 7.3 L F350 pulled in and gave me a jump.........took my cables and his on all 4 batteries

I guess there could be a problem with the ABS system but it just seems weird that the light came on when the batteries went dead from the bad alternator. Is it possible that there is a code stored that keeps the light on and that it just needs to be cleared?
