For some reason the alternator on the Caddy is not charging the battery so we got a new one after we had the old one checked and it showed it was good.......yes we did. After placing the new alternator on the car we checked with a volt meter and it did not appear the alternator was not charging the battery. My question is should the volt meter show 12.XX when the engine is on? I am not going to believe we have 2 bad alternators but for some reason they do not appear to be charging the battery. how can we confirm this? We have the positive connection going to the battery as well as the negative. Any help would be appreciated.
