Break camp, on the road again. Good Luck!
We had our alternator go out on our last road trip from SD to TN on the way back near Brookings, SD. I had it changed out in less than an hour. It really did look like I replaced the original alternator from 2000 and 232,000 miles later!
That is one issue I have had on my f350 with the 6.0 diesels .. Alternators ALWAYS have low voltage. Have replaced them a bunch of times. A guy showed me on time how to pull the belt and trap the belt tightener, have not been able to figure it out sense..
I think it's common on these Expeditions. I change an Expedition alternator quickly though it can be a tad hard if doing by yourself as the tensioner is pretty stout. I've gone through so many alternators that I keep a spare on hand. It's not pretty when the regulator goes out as when it happened to me, the voltage pegged out at about 17.6 volts. Every gauge, light, etc. goes crazy. It literally boiled the battery and fried my subwoofer amplifier so they had to be replaced too.
Glad you found the problem and are back in action.
About 1 hour into a 3 hour drive I saw my battery gauge was a little below half. 15 minutes later it was down more and obviously running off the battery. Made it another 35 minutes to a AutoZone.
Changed the alternator with the few crappy tools they had.
