Hey there, new to the forum hope you all are well. My 91 trooper 5speed got worked on recently new battery and all but the battery light came on this week and like an idiot i didn't pay attention to it. was driving this morning and it suddenly died on me and wouldn't start back up. Had someone come jump it for me but it wouldn't get out of second gear and it would buck. I think it maybe an alternator issue possibly? Would love some feed back if possible on what maybe the problem as well as any maintenance tips in general because I am a new trooper owner haha.

Thanks for any info!
