My alt is charging at 18volts what could be the problem

faulty voltage regulator
check with an accredited auto electrician as voltage regulators can be internal in the alternator, external and in the engine compartment or on later model cars , in the ECM
required voltage from a regulator is 14.5 -14.8 volts
any thing higher can boil a battery and destroy it or put excessive voltage into the electronics causing failures there

I have a 93 jeep grand cherokee changed altenator but still wont charge

If no damaged wiring is found, it's most likely an internal fault in the ECM (Engine control module, computer, PCM, ECU, whatever you want to call it, it goes by many names)
The Voltage Regulator is built into the ECM on virtually every Chrysler product (including Jeeps) after 1987 or so. And it is prone to failure. If it does fail, you either have to replace the ECM or install an External Chrysler Voltage Regulator, which requires some wiring harness modifications and a few parts that can be purchased at your favorite auto parts store.
To do the External conversion, you'll need :
1 Chrysler Voltage Regulator (virtually any Dodge/Plymouth from 1970 - 1986. It's best to order one for a 70's 4x4 Truck with a 318 engine though, to avoid any possible mix ups)
1 Chrysler Voltage Regulator Pigtail (this is the plug that connects to the regulator)
Roughly 10 feet of 14 gauge wire, possibly less, depending on where you want to mount the regulator.
Most, if not all Regulators now include a wiring diagram in the box, for this purpose, just follow the diagram and match up the field wires on the alternator with the ones in the diagram. On a '93 Jeep one field wire should be Blue, the other should be Green.
