Charging Problem

#2
Is your alt. a delco ? 1 wire or 3 wire ? Could be a lot of things , elec. conn. (clean, good), belts/pulleys ( slipping), Too many variables, need more info. If you don't have a service manual, GET ONE ( not the ones from chiltons a REAL factory service manual ). It is the best tool you can buy. Trouble shooting section works wonders.
