XJ low volts
When I start my Cherokee from time to time the check gauges light will come on and the volts on the battery will be at 9. When I turn it off and turn it back on it goes back to the middle. This doesn't happen every time I start it. Any ideas what could be wrong?

First thing I'd do is test the actual voltage at the battery with it running and make sure the alternator is charging.

Second on an actual reading.
Sounds though like your battery is on its way out.
When starting it should not drop below 10volts. If it does its got a bad cell.
Turn ignition on. Battery should read over 12. If not then it needs charged.
Starting motor it should not drop below 10(while cranking)
Running it should b at 13.5 to 15volts. Only if the battery is fully charged.

Head to your nearest parts store that offers free diagnostics. They'll test your battery,starter,alternator,and charging system. They'll also check for codes.
