SOURCE: 99 jeep cherokee sport 4.0l 6cyl voltage will go to 19v

The problem sounds intermittent, if you put volt meter on the battery while it is at that 19volt mark/reading(on the gauge cluster) you will be able to see if it is true. If your alternator is really charging over 16volts the lights should be getting brighter then usual and/or they are burning out. Find out ASAP, if the alternator has a defective voltage regulator, it needs to be replaced. Prolong use will damage components.

SOURCE: low voltage at low revs

hi this sounds like the alternator is faulty, there is a voltage regulator on or in the alternator to obviously regulate the voltage to the battery , say when lights are on it increases the voltage to the battery to adjust for the flow from the battery, would suggest you either get it checked or replace it...hope this helps

If you have verified low voltage using a scanner, keep in mind that some scanners will not differentiate no voltage from low voltage. Before testing, make sure the battery is fully charged and that all ground points are clean and secure. (in addition to the main battery cable to the block and fender, there are usually up to five more smaller wires on block and near the computer). Check all your fuses, especially those in the power distribution center.
To test further than that, you will need a good wiring diagram (chilton and haynes have diagrams but chilton seems to be more "readable" and accurate). First, follow test instructions in the manual and check each sensor. Then, use your multi-meter to check power at the computer harness plug, then follow the diagram and test wiring from the computer to the sensors, by disconnecting battery and using the ohm meter setting, checking for continuity from the computer harness plug to each sensor. (if you have a security system, find out how to re-set it before doing that) (Most commonly failed sensor is the crank sensor, followed by the cam sensor, so check both first) Most wiring problems happen at the connector ends either from a pin corroding (pin looks black) or where the wire joins to the pin.
Therefore, unless you see that a harness has burned or chafed through, normally you do not have to cut into taped areas. When working on a harness, it is often a good idea to use a notebook and write down the results, pin location and destination of each wire you check. That way, if an "odd" reading begins to show up in a shared wire, you can reference it to the diagram and get some idea of what is going on.
As you can see this is a bit complex....therefore I cannot give you a simple answer. If there, I'd need to do much the same as outlined above
In testing, you will invest some time, but will not be randomly replacing parts, hoping the problem will go away.

Your alternator is on the way out,replace with new or rebuilt. you can remove alternator and have it bench tested to be sure.

My 1999 jeep grand cherokee sometimes shifts wrong

check to see if your fluid is low or burnt. if it is low then just add enough to cover the fill mark on the dipstick. if it is burnt, remove the transmission pan and filter and replace the filter. then add new transmission fluid.

What is your Transmission Fluid Level? If Low, it could cause this signal.
When was the Transmission Fluid and Filter last changed? Was the correct fluid used?
I would have these changed as soon as possible.
There is a Transmission Temperature Sensor on 4-speed transmissions.. Check the Connection and Voltage on this Sensor.
Remove this sensor, clean, reinstall, and check to see if the light comes back on. If it does, remove and replace this sensor.

I have a ODB II code reader giving p1763, p1762, p0303

Your right about the two codes. It's really a transmission part.
As soon as you open up the transmission pan, it right there.

As for PO303, that is a missfire in cylinder #3

I hope I answered your question.

I have a 1997 Jeep Grand cherokee with code 1762

1762 has to do with too high or too low voltage from the governor pressure solenoid valve in the transmission.
To test this code accurately, you would need to have Chrysler connect their scan tool to it. With that, they can check the whole system.
The governor pressure sensor measures output pressure of the governor pressure solenoid valve. It is located in the governor body on the valve body transfer plate.
