Hello, the thing about Jeeps? they have a computer controlled charging system, The battery light is a gen***** *****ght indicating it is not charging, It can come and go , it all depends,Basically have to have charging tested at SAME time the light is on, The noise? this tends to lean more to the alternator, it could be working on/off straining etc, I lean to bad alternator but be advised, in some cases the regulator which is built into the PCM ( computer) can be at fault,Likley you have an alternator going out, just cna not be 100% without test if alt or PCM. I lean to the Alternator
