So i picked up a 90 integra gs 2 days ago for free... not a bad car interior is very clean outside is kinda good for its year. It has a 94 ls non vtec motor swapped into it. sat for a few months so I had to get it jumped. Would hold charge so i bought a new battery. Installed that and it ran for maybe 2 hours last night and it died just started it and got it home like 1 mile away. Today is died again when i was going to my brothers house. Now like i said the battery is brand new, and the altenator looks new as well meaning its still the color from teh factory and not covered with dirt. What could it be?

 

Alternator.

Remove it and take it to an autopart's store, they can check it for you.

 

ur alternator fuse is probably burnt. check that first!!

 

if its not the alternator check ground connection on it and at the fuse box, maybe its not connected right or the ground cable that goes from the alt to the fuse box is bad or someone messed around with it
