I need to know what else to do

What is your question?

My truck was idling and died, I hopped in it and absolutely no power anywhere and drained the batteries, I tried to get jumped and it killed the vehicle that was jumping me, so I changed out the alternator and blew the alternator fuse, I than re did all the battery cables to ensure there was no shorts anywhere, and it still won't work, and when I hook it up to jump it everytjing comes on but than my check gauges lights come on.. And still nothing.. It's a 2000 Dodge Ram 3500 2wd diesel.. Any help would be grest
