check Guage light
My gas guage doesn't work and I've noticed that my check Guage light will come on and battery indicator drops when I'm very low on gas! Put gas in and it solves problem for me. Weird jeep thing I guess.

Its a brand new battery and when I installed it I cleaned both the posts and terminals very well with a stiff wire brush.
However I went out there again and cleaned the terminals again and checked all engine grounds, it seems to have solved my problem.
I tested the alternator as well and its putting out 13.9v
Thanks for the advice guys.. Not really sure what the problem was... Must have just been a tj acting up..

Before doing anything (!) else, remove both battery connections and clean them and the battery posts with a wire brush until they are bright and shiny clean. Then reconnect them, making sure to get the nut & bolt tight enough so the connectors can't be moved around on their battery posts by a pretty good attempt by your hands.
Dirty/corroded/loose battery connectors cause more battery & charging system problems than anything else.

Battery gauge suddenly drops-check gauge light comes on
I have a 97 jeep tj, 2.5L.
It was running great, parked it to run in the house for a few minutes, went and started it up and, everything was normal, then all the sudden the battery volt meter dropped to 9 and the check gauge light came on.
I did a code read out by turning the key three times and got 12-47-55.
Code 47 -Battery voltage sense input below target charging during engine operation. Also, no significant change detected in battery voltage during active test of generator output circuit.
It still fires up on first crank, but the volt meter now reads 12, then about 2 minutes later it drops back to 9 or lower and the check gauge light comes on,
