90 ford taurus gl 3liter v6?

sounds like it ... local parts stores will check for free take it by..

btw taking cables off are ok on older cars but should not be done on newer cars voltage spike can damage or destroy elct. parts..

also you should have a full charge on your battery so you do not damage new alt.. and other parts

Yes, its shot. The airbag light sounds like another problem. The airbag has a reserve battery behind the glove compartment that lasts around an hour. Get a new altenator and stay away from Auto Zone and Advance Auto for altenators and starters. Oreillys (Ultima brand) is great if you have one close.

Take it to the auto parts store. They will test it for free. If you don't want to do that, test the battery with a multimeter. It should produce about 14 volts.

its like this mabe your wireing is working unfastened like have been the generating unit spliced wires togather to make the charging circut for the battery those spots i speek of contain usualy have been 3 or greater wires murge in to ine larger cord it quite is done via them soldering the wires togather and couvering it in rubber usualy a huge black around %. there fallow the yellow cord (i think of from the starter silinoid to the altinator u will ought to get rid of two million miles of electric powered tame , chop up loom and cord ties and use a easy telter to work out if that connection is dammaged on no longer if no longer thit set of mostlikely 3 wires have your altinator examined properly attempt the altinator attempt firse schucks usualy dose it for unfastened

Take it to Advance Auto or Pep Boys, wherever a free diagnostic can be done.

Bad alt.

yes. but i would refrain from doing that because on a good alt. the serge can fry your computer
