98 continental Bought new idler pulleys and alternator for my car to ellimimate some noises in the belt system. Old alt still worked but was noisy. Everything went fine with the installation. Put everything back in and i started the car . After a few minutes of idling battterie light comes on in the dash and i noitice the voltage of the batt is going down. So my diduction is new alt. is not charging . Steps i took to resovle the issue Checked harness plug going to the alt. Yellow/white wire is hot all the time . Green/? wire is hot with key on. Hotwired activation pin on alt. and still no charge . I think maybe the new alt. is bad. Installed old alt. in the car and still have the same problem even though it work a hour earlier. Rechecked harness plug with a test light still have good current . Toke harness plug apart and pluged each wire in the alt. Checked the fuse in the engine bay and it is fine. I don't know if there is one under the dash. So now the new alt. will not not charge and the old alt. also does not charge. Batt. light is still on in the dash with both alts. and it comes off when when i disconnect the alt. when car is running. I'm lost.
