Normal?

I had my battery tested, says it's good and has full charge. My battery meter never goes higher than this.. Sometimes lower..

Ideas?

If your Jeep has been exposed to the elements a lot you might have dirty connections on the back of the guage cluster, hell my amp meter does not work at all. There are a lot of posts on how to pull and clean it to make it work again.

Chances are it's the gauge, but I still would have the alternator checked out.

It starts up, It doesn't die, or loose power, I doubt the alternator has a problem. But I did think about that. I've had alternators go out before. There are no symptoms of that. Just the gauge doesn't ever rise above where it's at in the pic.

I'm thinking it's probably the gauge. Because my speedo doesn't work. All the others work just fine. But two of them don't work properly. There was a previous leak behind the dash during heavy rain. which is now fixed. That could have something to do with it.

Yes. There could be corrosion on the contacts. Most likely it's the gauge. But, regarding the alternator, any chain parts store can test it for you. Wouldn't you want to know/rule out a charging system problem along with the battery checking out ok? There are a number of ways alternators can start to go bad; internal regulator, diodes, bearings etc., even a loose or bad belt. Also, check the wiring plugged into the alternator. I would rule it out and then take out and check the gauge connections.

Volt meter

If you have a volt meter. Place the volt meter on battery and see what the reading is. Then With jeep idling place the volt meter on battery while running and see what the voltage is. That will tell you if the alternator is operating. Should be about 13.9 to 14.3.

That would work, but, I don't have a volt meter. I'll just run it up to the shop a little later on and have them check it for me.
