Alternator producing lots of battery acid. Replaced battery. Nada. When I purchased one new they tested the old and said okay. Hummm. Replaced voltage regulator. Nada. Puts out 12.3 volts on the battery terminals. Old one looked fine. No problem. Took it to Advance and they spun the alt on a machine. Putting out 14 volts. Removed neg battery cable from fender, cleaned and sanded connection. Belts okay. Now I have a touch less than twelve. There is a history of damage in the area due to the original battery acid problem. Oh, I did check the ground on the trans. Any input appreciated. Dave
