When my alternator went bad in my 2000 Ranger it was early AM & I had the lights on, the lights got dim, the CEL came on, the tach quit, & IIRC the gauges were reading very low. I tested the alternator with a digital volt meter & the output of the alternator was about 10.5 volts. Once I replaced the alternator all was good.
That's exactly what's happening to mine
Go out & get a inexpensive digital voltmeter either from Harbor Freight, or get one on line from Amazon, & test the alternator. Here is the link to the one I got.

Here is a link to the test procedure for a Ford alternator that I used.
