Oh well, I just stood on my head checking wires. My Delco "Remanufactured in Michigan" 80 amp alternator is not a joy for ever.
We put it in just before Du Quoin, perhaps 2500 miles ago. It was a whiner, but I guess I am too. The rear (I think, using the stick method) bearing began whining very soon after install. It is pretty noticeable at about 1200 RPMS. Not so much at road speed... or you don't notice it so much.
So, I thought, "Drive it." Bearings are easily fixed and I didn't want to ship it back.
Yesterday we took a short run to get out of the fog. 20 miles, plus. I heard, in addition to the usual whine a belt squeak. Not a squeal, just a chipmunk sort of squeak. I like it when my coach runs well, so I thought I will be glad when it has warmed up a bit and stops squeaking. Then I looked at my voltage gauge. 16+ Volts. I looked an my EBL screen and it showed the computer getting 16.9 volts.
Of course I stopped and shook hands with the little plug that will save my coach when the alternator runs away. On the rest of the trip up here it settled down twice. The rest of the time 16.9-16.4. I can't decide if the alternator or I whine the most.
I think I will put on an Autozone made in Outer Uptargastan. At least when it fails I can find a store and get another instantly.

Pulled my drive to work car(91 v6 manual Probe,lotsa fun)out of the garage and noticed the abs lite and one tunn signal lite on,,,,thats odd. Then noticed the voltage was high. Like really high. Smelled battery when I got to work,,,22 miles. Drove home,,,19.2 VOLTS,,,holy cow. Shut off,,,battery was boiling. Took alt apart and desoldered the regulator. Couple people on the probe forum said, just go get a rebuilt one!!! Cost about 20 bucks. Not that hard to work on. A solder sucker would have helped. You can work on them,,,,,,PL

For a lazy man, Autozone is the answer.
I've replaced mine about 5 times in 14 years...all free except for the first
one, and they have more outlets than McDonalds.

Well I am a little ashamed of myself. I traced wires again and checked plugs, wiggling everything. On the drive back voltage was on the money. Sorry Delco. Apparently it was the Beckman-Wadup wiring that was causing the trouble.
Which brings me to a question: On the plug there is a big wire and a little wire. The little wire is switched with the ignition. What happens if there was a fault?

George,
Look at that big wiring diagram on the wall of your shop. Oh, you don't
(yet) have one of those, do you? :-) Never mind:
The little wire (16 g. brown) is the one that's switched. That leads to the
infamous Nichrome wire and supplies initial excitation current to the field
of the alternator. If it's loose, you might not even notice, or the engine
might have to rev 'way up before the alternator output would come up. Or it
might never come up. It won't cause high output voltage.
The big wire (12 g. white) splices in a hidden place into the big (12 g.)
red wire which connects the Batt buss on the fuse block to the horn relay,
then via the fusible link to the battery junction block on the firewall.
That's the source of the reference voltage which the voltage regulator
tries to keep fixed around 13.8 VDC. Chances are that connector at the
alternator is in pretty bad shape -- most I've looked at are charred. If
that connection is bad enough for the regulator to be unable to detect the
battery voltage, the alternator output will climb to its internally
regulated limit, nominally 18 VDC. Sounds like your symptoms to me.
