Re: 99 Jeep Cherokee volts problem
Belt is loose or shined up....
They go loose when new especially....
Take the cold off engine and try to see if you can grab and spin the
alternator pulley by hand. If you can, see above...

1. Voltage drop is likely due to compressor clutch engagement. This is
normal. If the voltage drop is excessive, the charging system and/or
battery should be inspected for proper operation.
2. When the weather is cold and damp, even tightened belts can slip if
not tensioned properly. This slippage will often cause a squealing
noise, usually until it spins enough to dry out. Recheck the tension.
Cheap belts often make noise regardless of tension: install an OEM belt
if in doubt. (Goodyear Gaterback belts have always worked very well for
me as well.)

Re: 99 Jeep Cherokee volts problem
I'll second the Gatorback reccomendation. It's $34 if you go through
partsamerica.com and pick it up at your local Checker/Schucks/Kragen store.
Pull the belt and check the pulleys, make sure the tensioner is tight.
