Help Needed F-250,06,6.0 set now wont start.

[Gnome]

I drive the big truck over the road( kenworth). Came home after a month and 250 started then idled rough and stalled. now it will not start. charging batteries( how should i conect the charger, neg on one batteryand pos on the other?), what to do next, to get started?

 

[big_rooster]

hook both cables to 1 battery or the ground to a solid ground. Both batteries are tied together so it will charge them both.
