I recently bought an 83 s10 swapped with a throttle body 350. But they changed the throttle body out to carburated. The wires were a mess when I got it but we went through got rid of a bunch of unneeded b.s. Now I've got one problem. For the life of me I cant get the altenator to charge. I've put 3 used alternators on and a brand new one. The brand new one is on now. After removing all the wires from the altenator and testing straight off the hot post of the alternator I get .83 v. When testing with everything hooked up I'm staying at around 11.9 v. Now I'm lost on what could be causing this problem. I am to understand that I should be seeing around 13.5 v when running. I see about 11.02v with headlights on. Please ask any questions and I'll do my best to answer quickly so I can get this problem taken care of. I'm new to the v8 swapped s10 stuff but I do know a bit about mechanical work.
