2005 Other Plymouth Models 95 Plymouth Neon

Electrical problem
2005 Other Plymouth Models Two Wheel Drive Manual 125000 miles

I have a problem, I have a 95 neon sho 2.0. I just replaced the alt and batt. New cable too. My old alt
died due to the fact the one wire that conects to the bolt, (not the one that goes to the two pins)
somehow got fried and melted the plastic shroud.
as I said I replace the alt and batt. But my batt light keeps coming on after 5 min of driving. What else
should I be checking cant see anything visible
as far as wires go. Asap!
